Deputy commissioners and nodal officers appointed for COVID-19 management were also a part of the meeting, an official statement said.
Keshni directed them to further ramp up COVID-19 management preparations coupled with aggressive surveillance, stringent containment, swift contact tracing and focused clinical management along with proactive Information, Education and Communication (IEC) activities.
She said the capacity of hospital beds, adequate availability of personal protection equipment (PPE) kits and fatality management should also be done on a priority basis.
The official also noted that the need of the hour was to train final year MBBS, paramedic and nursing students to tackle any alarming situation.
The chief secretary directed the deputy commissioners to meticulously carry out the surveillance for Severe Acute Respiratory Infections (SARI) or Influenza-like illnesses (ILI) to detect any possible hidden infections at an early stage to ensure timely containment.
"Deputy commissioners have to ensure to gear up the strategies of COVID-19 management in Haryana by primarily emphasising on disease surveillance and then on treatment. Intensive IEC activities along with swift feedback mechanisms have to be developed through unit teams to identify high-risk cases," she added.
