New York [US], April 5 (ANI): The <keyword id="10561122" type="General" weightage="20" keywordseo="bird-flu-pandemic" source="Orion">bird flu pandemic</keyword> with the potential to be "<keyword id="21202249" type="General" weightage="20" keywordseo="100-times-worse" source="Orion">100 times worse</keyword> than COVID" may be on the horizon after a rare human case was discovered in Texas, experts have warned, the New York Post reported on Thursday. The <keyword id="21202246" type="General" weightage="20" keywordseo="H5N1-avian-flu" source="keywords">H5N1 avian flu</keyword> has spread rapidly since a new strain was detected in 2020 affecting wild birds in every state, as well as in commercial poultry and backyard flocks. But the recent cases detected in mammals, with cattle herds across four states becoming infected and on Monday, federal health officials announced that a dairy worker in Texas caught the virus. "This virus [has been] on the top of the pandemic list for many, many years and probably decades," Suresh Kuchipudi, a <keyword id="95867" type="General" weightage="100" keywordseo="bird-flu" source="Orion">bird flu</keyword> researcher from Pittsburgh, said at a recent panel discussing the issue, the New York Post reported citing the Daily Mail. "And now we're getting dangerously close to this virus potentially causing a pandemic." He noted that the <keyword id="565908" type="General" weightage="20" keywordseo="H5N1-virus" source="Orion">H5N1 virus</keyword> has already been detected in species throughout the world and "has shown the ability to infect a range of mammalian hosts, including humans." "So therefore, in my view, I think this is a virus that has the greatest pandemic threat [that is] playing out in plain sight and globally present," Kuchipudi said. John Fulton, a pharmaceutical industry consultant for vaccines and the founder of Canada-based BioNiagara who organized the meeting, also expressed his concerns, the Mail reports, the New York Post reported. "This appears to be 100 times worse than COVID -- or it could be if it mutates and maintains its high case fatality rate," he said. "Once it's mutated to infect humans, we can only hope that the [fatality rate] drops." Around 52 per cent of humans who have contracted H5N1 since 2003 have died, according to the World Health Organization. For comparison, COVID currently kills less than 0.1% of those it infects -- though at the start of the pandemic, the fatality rate was around 20 per cent. Symptoms of the bird flu are similar to those of other flus, including cough, body aches and fever, the New York Post reported. Some people may not develop noticeable symptoms, but others can develop severe, life-threatening pneumonia. The dairy worker in Texas who was infected has reported "eye redness (consistent with conjunctivitis)" as their only symptom, the Centers for Disease Control and Prevention noted. "The patient was told to isolate and is being treated with an antiviral drug for [the] flu," the CDC said. The agency and "the whole US government is taking this situation very seriously," CDC Director Mandy Cohen told the Washington Post. She maintained that the virus does not pose much of a risk to the general public, noting that the dairy worker was in direct contact with infected cattle, and the US Department of Agriculture has said there are currently no changes that would make it more transmissible to humans. "While cases among humans in direct contact with infected animals are possible, this indicates that the current risk to the public remains low," the department said in a statement over the weekend. But the fact that the virus has been found in cattle could mean it is starting to mutate, Cohen told the Washington Post. "We had not seen avian flu in cattle prior to last week. That is new," she said. "It is a reservoir for [the] virus to circulate and potentially change." If the virus does mutate enough to infect humans, it could spread rapidly, the European Food Safety Authority warned on Wednesday, according to Fox News. "If avian A [H5N1] influenza viruses acquire the ability to spread efficiently among humans, large-scale transmission could occur due to the lack of immune defences against H5 viruses in humans," the Food Safety Authority said. To prevent any potential spread, the US is already testing components used to create a vaccine for the virus, and two candidate vaccine viruses appear to be well-matched to protect against H5N1, the Washington Post reports. White House press secretary Karine Jean-Pierre also said the Biden administration is monitoring the threat. "We take the health and safety of the American people seriously," she said at her briefing on Wednesday. "It is very important to this president. Our top priority is to keep communities healthy, safe and informed."

Scientists warn of bird flu pandemic that could be '100 times worse' than COVID after rare human case found in US

In recent months the <a target="_blank" href="https://www.businessinsider.com/bird-flu-avian-influenza-outbreak-us-h5n1-wiping-out-everything-2023-4">highly pathogenic H5N1 virus</a> has been spreading through US cattle herds for the first time ever. The cow-to-cow transmission is the latest escalation in a global <a target="_blank" href="https://www.businessinsider.com/egg-prices-poised-to-spike-again-thanks-to-avian-flu-2023-12">outbreak</a> that began when the virus reemerged in Europe in 2020. It has since killed tens of millions of birds and more than 40,000 sea lions and seals in South America. World Health Organization chief scientist Jeremy Farrar <a target="_blank" href="https://news.un.org/en/story/2024/04/1148696">called</a> this an "<keyword id="20925201" type="General" weightage="20" keywordseo="animal-pandemic" source="Orion">animal pandemic</keyword>" on April 18. Genetic fragments of the virus, discovered in grocery store milk on Tuesday, suggest the <keyword id="21439799" type="General" weightage="20" keywordseo="cattle-outbreak" source="Orion">cattle outbreak</keyword> is more widespread than officials believed, The Washington Post <a target="_blank" href="https://www.washingtonpost.com/health/2024/04/23/bird-flu-virus-milk/">reported</a>. Experts told the Post that <a target="_blank" href="https://www.businessinsider.com/bird-flu-eggs-meat-milk-dairy-safety-during-outbreak-2024-4">drinking pasteurized milk is probably still safe</a>. Pasteurization deactivates pathogens, probably including H5N1, according to the Food and Drug Administration. However, no studies have specifically tested whether pasteurizing milk deactivates H5N1. According to <a target="_blank" href="https://www.nytimes.com/2024/04/19/health/bird-flu-usda-cattle.html">the New York Times</a>, the FDA is testing that now. <div type="image" title="row of cows sticking their heads through metal bars to eat hay feed" height="1500" width="2250" msid="109603130" hostid="261"></div>One human in Texas has tested positive for the virus after exposure to dairy cattle. <a target="_blank" href="https://www.cdc.gov/media/releases/2024/p0401-avian-flu.html">According</a> to the US Centers for Disease Control and Prevention, that person's only symptom was eye redness. There has been no known human-to-human transmission. Still, future mutation could allow the virus to spread more easily to and between humans — a possibility of "great concern" to Farrar. <div type="image" title="man with turkeys inside coop. sign outside reads 'biosecurity area - no admittance w/o owner permission" height="1400" width="2100" msid="109603131" hostid="261"></div>Dr. Jerome Adams, a former surgeon general and the director of health equity at Purdue University, is getting deja vu. "If it keeps spreading in animals, then it is eventually going to cause problems for humans, either because we don't have food because they've got to start exterminating flocks, or because it starts to make a jump in humans," Adams, <keyword id="6366244" type="General" weightage="20" keywordseo="who" source="Orion">who</keyword> served under former President Donald Trump and was on the administration's initial COVID-19 task force, told Business Insider. "The more it replicates, the more chances it has to mutate." Though he agrees with the CDC's <a target="_blank" href="https://www.cdc.gov/flu/avianflu/inhumans.htm">assessment</a> that the current risk to humans is low, Adams fears the US is repeating many mistakes it made in the early days of COVID-19. <h2>Weak messaging with no clear leaders</h2>Who is in charge of an animal pandemic in the US? The CDC? The US Department of Agriculture? The FDA? The answer is, sort of, all of them. That decentralized responsibility could be behind the lack of widespread, clear public messaging so far. For example, Adams says he hasn't changed anything about his diet, since pasteurization and proper cooking procedures should kill any live virus present. But he isn't sure everyone is getting the message. He compared it to the development of COVID-19 vaccines, when people distrusted a process they didn't understand. <div type="image" title="person with ponytail green hoodie medical gloves inspects eggs in a grocery story" height="1500" width="2000" msid="109603133" hostid="261"></div>"The public needs good consistent communication from the White House, from the USDA, helping reassure them what the process is to keep them safe," Adams said. Rather than consumers, the people most at risk are agricultural workers or anyone with close or prolonged exposure to chickens or cattle. It's those groups who need strong, targeted guidance right now, Adams said. <h2>Only testing the sick</h2>So far, the USDA has only been testing <a target="_blank" href="https://www.businessinsider.com/beef-prices-higher-drought-fewer-cattle-less-meat-2022-8">cattle herds</a> when an animal appears sick. That means asymptomatic spread could be flying under the radar. "An animal can't tell you, 'Hey, I feel a little under the weather today.' So they're literally waiting until an animal is collapsing or showing fatigue or showing severe symptoms," Adams said. "We need a testing strategy that is proactive and allows true surveillance, and not reactive." The USDA took a step forward on Wednesday, ordering that all lactating dairy cows must be tested for H5N1 before they're moved across state lines and that all positive test results must be reported. New York Times columnist Zeynep Tufekci <a target="_blank" href="https://www.nytimes.com/2024/04/24/opinion/bird-flu-cow-outbreak.html">reported</a> that same day that, until now, the USDA has not been keeping track of positive test results in cattle. <h2>Election distraction</h2> <div type="image" title="donald trump" height="3333" width="5000" msid="109603134" hostid="261"></div>In late 2019 and early 2020, the big news story was the impeachment, and later acquittal, of President Trump. Now a different <a target="_blank" href="https://www.businessinsider.com/donald-trump-hush-money-trial-kicks-off-fiery-da-openings-2024-4">Trump trial</a> is dominating the news. And, as in 2020, this is an election year. "The Biden administration, particularly the White House, has been incredibly quiet on this bird flu situation. Why? To me, it looks like they very much don't want to scare the public and spook the economy in an election year," Adams said. <h2>Business vs. public health</h2>Just like the lockdowns of COVID-19 were devastating for the restaurant and hospitality industries, a crackdown on avian flu can be devastating to the chicken industry. The treatment for a <keyword id="1433269" type="General" weightage="20" keywordseo="bird-flu-outbreak" source="Orion">bird flu outbreak</keyword> is to kill all the chickens. Even before that, just testing the flock can slow down production. "We're seeing the same tension between business interests and public health interests," Adams said. What's more, many of the workers who handle chickens and cattle are undocumented immigrants. That can make them and their bosses hesitant to call in authorities over diseased animals. Many vulnerable groups were hesitant to report illness in the early COVID days, too, including migrant workers and people who didn't have sick leave from work. "My concern is we keep making the same mistakes over and over again," Adams said. "Because we keep focusing on the wrong things instead of focusing on the root causes."

Bird flu could jump to humans any day. A former surgeon general says it feels like 2020 again.

Kolkata (West Bengal) [India], June 12 (ANI): The World Health Organisation has confirmed the human case of <keyword id="3653784" type="General" weightage="20" keywordseo="bird-flu-in-india" source="Orion">bird flu in India</keyword>, after the <keyword id="15897682" type="General" weightage="20" keywordseo="H9N2-virus" source="Orion">H9N2 virus</keyword> was detected in a four-year child in West Bengal. Overall, this is the second <keyword id="21166335" type="General" weightage="20" keywordseo="human-infection" source="keywords">human infection</keyword> of <keyword id="2663051" type="General" weightage="20" keywordseo="Avian-Influenza-A" source="Orion">avian influenza A</keyword> (H9N2) notified to WHO from India, with the first being done in 2019. The child has recovered and was discharged from the hospital. WHO received a notification from the International Health Regulations (IHR) National Focal Point (NFP) for India, regarding a human case of avian influenza A(H9N2) virus infection in West Bengal, the health body said in a press release. "The patient is a 4-year-old child residing in West Bengal state. The case, previously diagnosed with hyperreactive airway disease, initially presented to the paediatrician with fever and abdominal pain on 26 January 2024. He developed seizures on January 29 after which he was brought to the same paediatrician. The patient was admitted to the pediatric intensive care unit (ICU) of a local hospital due to the persistence of severe respiratory distress, recurrent high-grade fever and abdominal cramps. The patient tested positive for influenza B and adenovirus. He was discharged from the hospital on February 28 but with a recurrence of severe respiratory distress, he was referred to another government hospital and was admitted to the pediatric ICU and intubated on March 3. His nasopharyngeal swab was sent to the Kolkata Virus Research and Diagnostic Laboratory and tested positive for influenza A (not sub-typed) and rhinovirus. On April 26, the sample was sub-typed as influenza A(H9N2) through a real-time polymerase chain reaction. The patient was discharged from the hospital with oxygen support on May 1. WHO said that the infected patient had exposure to poultry at home and in the surroundings. It, however, also affirmed there were no known persons reporting symptoms of respiratory illness in the family, the neighbourhood, or among healthcare workers at health facilities attended by the case at the time of reporting. The health body further warned that sporadic human cases could occur in the future as this virus is "one of the most prevalent avian influenza viruses circulating in poultry in different regions." Animal influenza viruses normally circulate in animals but can also infect humans. Infections in humans have primarily been acquired through direct contact with infected animals or through indirect contact with contaminated environments. Depending on the original host, influenza A viruses can be classified as avian influenza, swine influenza, or other types of animal influenza viruses, the WHO stated in the release. The health body further said that it is providing continued support to the government of India through technical advice, updates on risk assessment and updating contingency plans- both in the human and animal sectors in line with the global guidance.

The Food and Drug Administration <a target="_blank" href="https://www.fda.gov/food/alerts-advisories-safety-information/updates-highly-pathogenic-avian-influenza-hpai">announced</a> Tuesday that it had discovered virus particles in "some of the samples collected" throughout the milk supply chain, from the cow to the shelf. The agency did not indicate how many samples tested positive or from where, but said the detections "do not represent actual virus that may be a risk to consumers." However, the discovery suggests the virus has spread further through the <keyword id="21438910" type="General" weightage="20" keywordseo="US-cattle-population" source="Orion">US cattle population</keyword> than officials previously realized. Scientists are growing more concerned that this <keyword id="109029" type="General" weightage="20" keywordseo="avian-influenza" source="Orion">avian influenza</keyword> outbreak could make the <a target="_blank" href="https://www.businessinsider.com/bird-flu-cattle-outbreak-repeat-mistakes-former-surgeon-general-warning-2024-4">jump into human-to-human transmission</a>. So far, though, many public health experts don't think this rings alarm bells about the <a target="_blank" href="https://www.businessinsider.com/bird-flu-eggs-meat-milk-dairy-safety-during-outbreak-2024-4">safety of the food supply</a>. "I had eggs yesterday and I had milk last night, and I'll have a steak if someone gives me a steak," Dr. Jerome Adams, who was the surgeon general of the Trump administration and is now the director of health equity at Purdue University, told Business Insider on Wednesday. "I still believe that the way we process and cook foods is going to disable most bacteria and viruses, including this one," he said. <h2>Pasteurization should kill H5N1 in milk</h2> <div type="image" title="row of cows sticking their heads through metal bars to eat hay feed" height="1500" width="2250" msid="109605298" hostid="261"></div>The FDA oversees the nation's milk supply, and the US Department of Agriculture oversees dairy cows. Both say they believe the commercial milk supply is safe, due to the pasteurization process and the practice of disposing of milk from sick cows. Pasteurization heats milk at a high temperature for a brief period of time to kill microbes living inside it. Some states allow the sale of unpasteurized, aka "raw," milk or cheese, which the CDC recommends avoiding. Public-health experts told <a target="_blank" href="https://www.washingtonpost.com/health/2024/04/23/bird-flu-virus-milk/">The Washington Post</a> and <a target="_blank" href="https://www.nytimes.com/2024/04/23/health/bird-flu-milk.html">The New York Times</a> on Tuesday that they, too, believe <keyword id="1476604" type="General" weightage="20" keywordseo="pasteurized-milk" source="Orion">pasteurized milk</keyword> to be safe, but that the federal government should still conduct tests to confirm that. The FDA says such tests are ongoing. <div type="image" title="cow udder rigged with machine and tubes for milking" height="1500" width="2250" msid="109605301" hostid="261"></div>"It's taking them too long to be able to reassure the public about the safety of milk," Adams said. Some studies have shown that pasteurization deactivates H5N1 in eggs, the FDA says, and that happens at a lower temperature than milk pasteurization. "To date, we have seen nothing that would change our assessment that the commercial milk supply is safe. Results from multiple studies will be made available in the next few days to weeks," the FDA statement said. <h2>To be extra safe, cook meat and eggs all the way</h2>There's probably no "significantly increased risk," Dr. Samuel Alcaine, an associate professor of food science at Cornell University, told Business Insider on April 6, but you can <a target="_blank" href="https://www.businessinsider.com/bird-flu-eggs-meat-milk-dairy-safety-during-outbreak-2024-4">be extra safe by fully cooking your meat and eggs</a> (until the yolk is firm). <div type="image" title="Person using spatula to cook steak in frying pan" height="1808" width="3000" msid="109605302" hostid="261"></div>Adams says he doesn't normally eat rare steak or runny eggs anyway. "That has nothing to do with H5N1. That's just me being someone who's been in public health and food safety for a long time," he said. His wife does eat runny eggs and rare steak, though, he added, "and I'm not telling her to change what she does." He added that people should still follow basic food-safety practices: Wash your hands after handling raw meat or eggs, and before handling the food you'll eat. Prevent cross-contamination from raw meats or eggs and the utensils that have touched them. Always cook poultry to an internal temperature of at least 165 degrees Fahrenheit. <h2>The biggest bird flu risk for humans isn't food</h2>The people who are really at risk for bird flu are those who work closely with chickens, cattle, or other livestock. The CDC <a target="_blank" href="https://www.cdc.gov/flu/avianflu/hpai/hpai-interim-recommendations.html">says</a> those workers should avoid unprotected, direct contact with sick animals, raw milk, animals' drinking water, animal carcasses, feces, litter, or other surfaces that could be contaminated with animals' saliva, blood, or other excretions. Workers should be provided with <a target="_blank" href="https://www.cdc.gov/flu/avianflu/h5/worker-protection-ppe.htm">personal protective equipment</a> for those situations and trained to use it properly, the agency says. "It's spreading rapidly in these animals, and every time it spreads, it has a chance to mutate," Adams said.

Bird flu particles were found in pasteurized milk. A former surgeon general says he isn't changing what he eats.

Chennai Mayor <keyword id="3346795" type="General" weightage="50" keywordseo="priya-rajan" source="Orion">Priya Rajan</keyword> also joined the Health Minister in inspecting the camps. "About 1000 fever camps have been set up all over Tamil Nadu of which 200 fever camps are in Chennai," Health Minister said. Recently, H3N2 virus fever broke out across the country sparking concerns. The Indian Council of Medical Research (ICMR) in a statement asked the administrations all over to comply with the safety protocols and take necessary precautions. People have been instructed to wear masks and maintain proper hygiene to avoid the virus infection. "Apart from the fever camps, about 11,333 public health centres in the state have been instructed to conduct frequent fever check-ups," said the minister in the statement. "We have adequate medicines for the fever. As of now, there are no severe cases and there is no need to panic." The Health Minister added, "According to ICMR, we have to be cautious with H3N2 virus spread like we were during the Covid Pandemic. People with fever symptoms should isolate themselves as per ICMR guidelines to prevent spread." Reportedly, corona cases have also been increasing in Tamil Nadu and also India, in general. "RTPCR tests are done and the number of tests has been increased. There were only 2 cases last month but now it's 20 to 25 cases in Tamil Nadu and we are preparing to curtail it," assured the Health Minister. Health Minister also said, "As of now it's not a community spread of H3N2 virus in Tamil Nadu. We are taking precautions to make sure it does not spread rapidly and turn into a community spread. I appeal to the people of Tamil Nadu to avoid going to public places if they identify themselves with the symptoms and immediately inform the authorities." According to the administration, the mega fever camps will continue their operations on Saturday, Sunday and also in the coming days in the state.

The statement also said that studies in mice indicate this type of genetic mutation in the virus is associated with more severe disease and enhanced viral replication.That doesn't make it a human virus yet, though.Other than this one change, H5N1 has mainly "avian virus properties and not human virus properties," Richard Webby, a virologist at St. Jude and director of the WHO Collaborating Centre for Studies on the Ecology of Influenza in Animals and Birds, told BI.That means the virus is better adapted to thrive and spread among birds, not humans.Still, that could change.<h2 id="ddfee4b3-1706-4652-9418-5ae34679d762">The latest US case had a troubling cough</h2>The first two farmworkers to test positive for H5N1 in the US had <a target="_blank" href="https://www.businessinsider.com/guides/health/treatments/pink-eye-treatment">pink eye</a>.

The CDC has reported no evidence that the coughing farmworker spread the virus to anyone else.But that doesn't mean H5N1 can't mutate to achieve human-to-human transmission — which brings us to the second unfortunate reality of this farmworker's respiratory infection. Compared to the eyes, human lungs are a more convenient place for an avian virus to get more mammalian, according to Webby. In the lungs, the virus is exposed to more of the cell receptors that a mammalian virus would bind to, giving H5N1 more opportunity to mutate and start grabbing onto those receptors — thereby becoming better adapted to infecting and spreading between humans.Many experts fear the USDA and CDC aren't monitoring cattle and farmworkers closely enough to catch concerning mutations early, and that other human cases may be going undetected.<div type="image" title="blue gloved hands in a white lab coat hold a large syringe and a lab tube of fluid" height="1500" width="2250" msid="110949093" hostid="261" sizebytes="47636"></div>"I think there's enough of a threat here to be very alert so that we have a surveillance system in place that, as soon as this happens, we can find it," Dye said.<h2 id="048d06aa-b91d-4421-b98b-5ae259b70f87">Vaccines are in the works</h2>The good news is that bird flu is <a target="_blank" href="https://www.businessinsider.com/august-flu-vs-covid-infection-rate-2023-8">not COVID-19</a>.

Why 4 new bird flu developments have experts worried about the virus

With the sudden increase of influenza A subtype H3N2 cases across the country raising concerns, a health expert at Delhi's Sir <keyword id="4014646" type="General" weightage="80" keywordseo="gangaram-hospital" source="Orion">Gangaram Hospital</keyword> on Thursday pointed out that the pattern of viruses has changed remarkably and unexpectedly in the past six months. Hospitals across the country are reporting thousands of cases of H3N2 influenza. According to <keyword id="6195115" type="General" weightage="80" keywordseo="dr-dhiren-gupta" source="Orion">Dr Dhiren Gupta</keyword>, Senior Consultant, department of paediatric emergency and critical care, Sir <keyword id="222793" type="General" weightage="80" keywordseo="gangaram" source="Orion">Gangaram</keyword> hospital, said, "Over the past 6 months pattern of viruses has changed remarkably and unexpectedly. Normally, we expect influenza as the number 1 virus which can lead to hospitalisation. This time Influenza A virus subtype H3N2 has led to a lot of respiratory tract infections." <keyword id="1989242" type="General" weightage="80" keywordseo="dr-gupta" source="Orion">Dr Gupta</keyword> further said, "Another observation- type B influenza (past two months 5 leading to <keyword id="1334956" type="General" weightage="80" keywordseo="picu" source="Orion">PICU</keyword> admission) has led to more severe pulmonary infections in form of ARDS, severe pneumonia requiring ventilation." He said that another virus which is leading to serious disease is an adenovirus. "Over the past 2 months, there is a significant rise in adenovirus leading to intensive care unit admission. (11 patients required PICU over two months (Jan, Feb 2023) vs 17 in last 1 year (Jan till December 2022)," he pointed out. Further explaining adenovirus, Dr Gupta said that DNA virus mainly affects the upper respiratory tract, and eyes and spreads like COVID. "Adenovirus is a DNA virus, with more than 60 subtypes, severe disease has been associated with serotype 7, 14, serotype 5, 21, 14. Mainly affect the upper respiratory tract, and eyes. It can cause pneumonia in immunocompromised. Spread like COVID. Previously thought that this virus mainly affects less than two years and immunocompromised but this year its behaviour was very different, Cidofovir can be used in progressive disease in immunocompromised." he explained.

What to know about H5N1 bird flu in humans as a girl dies in Cambodia and her father tests positive

Autism spectrum disorder is a severe neurodevelopmental childhood disorder characterised by impaired communication, lack of social skills and repetitive behaviour. The disease has its onset in childhood. "Our null findings are important since some people have suspected that vaccinations could cause autism, and the anti-vaccine movement seems to be growing in the Western world," said study lead author Jonas F Ludvigsson from <keyword id="9779400" type="COMPANY" weightage="20" keywordseo="the-karolinska-institutet">the Karolinska Institutet</keyword> in Sweden. While some studies indicate that influenza vaccination during pregnancy protects against morbidity in both the woman and her offspring, the long-term risks of H1N1 vaccination during fetal life have not been examined in detail. However, two recent studies were unable to rule out that offspring to women undergoing influenza or H1N1 influenza vaccination during pregnancy, and especially during the first trimester, were at increased risk of autism spectrum disorder. Now, a large study by researchers, published in the journal Annals of Internal Medicine, refutes any such association.Researchers, linked vaccination data in pregnant women from seven Swedish healthcare regions in 2009-2010 to the Swedish Medical Birth Register and the Swedish National Patient Register to identify autism spectrum disorder in the offspring. Of the 39,726 vaccine-exposed children, 394 had a diagnosis of autism spectrum disorder during the six-year follow-up compared with 330 among 29,293 unexposed children. The researchers adjusted their analyses for such confounders as maternal smoking, height-weight, maternal age and comorbidity in order to minimize the influence of other factors that might explain any association between vaccination and autism. Adjusting for potential confounders, H1N1 vaccine exposure during fetal life was not associated with a later childhood diagnosis of autism spectrum disorder. Results were similar for vaccinations in the first pregnancy trimester. "H1N1 vaccination has previously been linked to an increased risk of narcolepsy in young people, but vaccinating pregnant women does not seem to influence the risk of autism spectrum disorder in the offspring," Ludvigsson said. "Vaccination research has never been more important. Anticipating a vaccine against COVID-19, millions of pregnant women are likely to be offered such a vaccination," he added.

Swine flu vaccination given to pregnant woman may not cause autism spectrum disorder in offspring, says study

An <keyword id="6364396" type="General" weightage="80" keywordseo="icmr" source="Orion">ICMR</keyword> survey has shown that 50 per cent of the respiratory infection cases admitted to hospitals in over two month are of H3N2 influenza, the government told the Lok Sabha on Friday. A total of 1,161 cases of H3N2, which is a subtype of seasonal influenza virus, have been reported between January 1 and March 20, Minister of State for Health Bharati Pravin Pawar said in a written reply. She said most of these cases showed symptoms of cough and fever. The minister said H3N2 is a viral respiratory infection and antibiotics have no role in its treatment. However, she added, sometimes in a respiratory infection a bacterial infection may also occur and therefore physicians may prescribe an antibiotic to take care of the secondary bacterial infection.
