New Delhi, The Centre on Tuesday asked states and Union Territories to ensure that people taking part in mass gatherings and pilgrimages are asymptomatic and preferably fully vaccinated against Covid-19.

"All states/UTs, where such mass gatherings/yatras are proposed to be held should widely publicise that all individuals planning to participate in such gatherings/events are asymptomatic and preferably fully vaccinated against Covid-19," Union Health Secretary Rajesh Bhushan in a letter to the states and UTs.

He said if needed, a special drive for primary vaccination and precaution dose administration to all eligible people may be taken by the administration at least a fortnight in advance for those planning to join. Further adequate publicity and arrangement for testing (RTPCR & RAT) shall be done across multiple locations, he added.

While the trajectory of Covid-19 cases has declined significantly from levels that were observed in earlier part of this year, a few states and UTs across the country are witnessing a sustained upswing in the cases currently, he said in the letter.

The Centre has underlined need to enhance focus on five-fold strategy of test-track-treat-vaccination and adherence to Covid-19 appropriate behaviour.

"During many such events/yatras, lakhs of individuals undertake intra- and inter-state journey spanning hundreds of kilometres with halting points arranged by volunteers and community-based social/religious organisations. Such congregations may potentially facilitate transmission of infectious diseases, including Covid-19," Bhushan said.

The Centre has said that in the events like religious yatras, where en-route congregation points are expected, state governments concerned shall identify major routes expected to be taken by individuals and organise requisite health facilities on these routes.
