Recent Covid data indicate only localized spikes in some districts and not the onset of a widespread 4th wave. Dr. Samiran Panda, additional director general of the Indian Council of Medical Research (ICMR), told. Some regions of the country have registered spikes in Covid positivity rates. But, Dr. Panda said these increases are mostly due to low testing. He cited the example of Delhi where test positivity dipped to below 5% (from 7%) as soon as testing increased among symptomatic people. Dr. Panda said, so, positivity should be calculated when test performance in a district or in a state is at adequate levels. And achieving the prescribed number per defined population.
Dr. Panda also said only some districts are showing small increases in caseloads. What we’re seeing are blips and not the start of a new Covid wave caused by a variant. These blips are currently restricted to certain geographies and not uniformly spread across the country or a state. That, so far, there has been no indication of a 4th surge.
Several districts in Shanghai put up metal barriers last weekend as part of the city’s battle against a Covid-19 outbreak. In a move that drew protests and anger from some residents. Workers in white head-to-toe protective gear erected mesh wire fences and metal sheets to block off roads. Residential communities and even the entrances of some apartment buildings. A majority of the city’s 25 million residents had already been prevented from leaving their homes during a month-long lockdown. Though some neighborhoods have since opened up.
