Another baby in England was diagnosed with the coronavirus on Tuesday, becoming the third such infection in the UK alone.

The baby was one of three people to test positive at James Paget University Hospital in Gorleston, a seaside town in Norfolk county, the hospital confirmed to Business Insider. The regional Eastern Daily Press first reported the news.

The age and condition of the baby in Norfolk are not immediately known. James Paget University Hospital told Business Insider that the two other patients are adults, but declined to give further details.

All three patients have been put in isolation, and the hospital is now conducting "contact tracing" to see if anyone might have had face-to-face contact with them, according to a Tuesday statement from the hospital.

On Monday, a nine-month-old baby in Manchester, England - named Cassian Coates - as also diagnosed with the disease after suffering a cold and a fever for several days, Sky News reported. The family is now self-isolating, and the baby is recovering, Sky News said.

And last Saturday, a newborn baby in London also tested positive for the coronavirus, becoming the world's youngest patient. The baby is now recovering, The Sun reported.

The London baby's mother had been unaware that she had the virus and was thought to have pneumonia, according to The Sun.

The coronavirus, which has spread to 155 countries, have largely affected the elderly and those with preexisting conditions.

Experts are still trying to figure out why the disease seems to impact youngsters less, and studies of the disease's spread in China suggest that only a handful of babies have been infected there.
