Trace 25-30 contacts of each COVID-19 case, create larger containment zones: Centre

Tracing 25 to 30 contacts of each COVID-19 case, proper isolation and creating larger containment zones were among steps the Centre has asked states to adopt for tackling the surge in COVID-19 cases. Calling for a district-centric approach to fight the upward swing in cases, Union Health Secretary Rajesh Bhushan said on Tuesday that each district, irrespective of whether it is seeing a surge or is with low burden, should formulate an action plan with clear timelines and responsibilities.
Bhushan said the virus can be contained by quarantining and testing individuals suspected to be COVID-19 positive as well as 25 to 30 close contacts of positive persons, isolating, quarantining and testing them. "Where there are clusters of cases, simply quarantining individuals or families will not help. In that case, larger containment zones with clear boundaries and stringent controls must be implemented," he said.
In a letter to all chief secretaries, Bhushan said COVID-appropriate behaviour must be enforced using the Police Act, or powers under the Disaster Management Act. The states have also been asked to map cases based on surveillance activities and focused testing in areas, reviewing sub-areawise indicators like case positivity rate, rate of growth of cases, case fatality, doubling rate of cases, on a real-time basis.
They have also been asked to review the proportion of Rapid Antigen Tests and RT-PCR tests. "All districts with high caseload and fast growth of cases must ensure saturation vaccination of priority age groups of 45 years and above in the coming two weeks," Bhushan said in the letter.
He said many districts in the country are seeing emergence of clusters of cases because of specific events and crowding, or where a large number of people are in close physical contact coupled with lack of COVID-appropriate behaviour. Efficient implementation of the 'Test Track and Treat' strategy remains the only proven strategy for controlling transmission, Bhushan said. The states were asked to identify localities and hospitals where deaths are high.
"Do an analysis (death analysis) to understand the system-related issues of why the death happened whether it was due to late detection (surveillance failure) or late admission in hospitals (delay in referral), or due to clinical care at hospitals (non-adherence to clinical management protocols, lack of oxygen lack of beds, non-transparent procedure of bed allocation). Such issues must be promptly redressed," he said.
Bhushan said some districts that saw a high number of cases in August-November are again seeing a high growth rate of cases. "Additionally, a number of new districts that saw a limited prevalence earlier are worryingly showing a surge in cases. States and UTs that currently have low levels of cases, however, cannot be complacent," the health secretary said.
He said a lack of COVID-appropriate behaviour and laxity in public health effort can lead to a sudden surge. "If immediate, proactive and focused action is taken by your teams right now, it will be possible to ensure that the infection does not spread into currently low prevalence districts," Bhushan told the chief secretaries.
