Why COVID cases are rising again in some states

After India’s deadly second wave in April and May, cases declined all over the country, even as restrictions eased. The past couple of months have seen a spike again in Maharashtra and Kerala.

Maharashtra on Wednesday reported 3,783 new coronavirus cases and 56 fatalities, taking the infection tally to over 6,500,000 and the toll to over 138,000. Kerala confirmed a total of over 4,400,000 cases with nearly 23,000 deaths.

Experts are warning of a potential third wave in October amid the upcoming festival season, with the Ganesh Chaturthi festival kicking off Friday.

State governments are introducing measures to clamp down on mass gatherings.

"The third wave is not coming, it is already here," Mumbai's mayor Kishori Pednekar told reporters on Tuesday.

India steps up healthcare measures

In a meeting last week, the central government emphasized that there was no room for complacency when it comes to preparedness.

Prime Minister Narendra Modi said efforts were being made to increase hospital bed capacity and oxygen availability, as part of the government's COVID Emergency Response Package II.

Rijo M. John, a health economist based in Kerala, said: "Cases in Kerala are high because it still has a high proportion of uninfected population, and the delta variant is still catching up."

But following a spike, John says case numbers in both Maharashtra and Kerala are beginning to stabilize.

"The cases [especially the 7-day averages] are not rising… In both states, it is either steady or declining," he told DW.

High vaccine numbers give hope

India's vaccination program has also gained pace despite a slow start. The country now has the highest number of people in the world to have received at least one dose of the COVID vaccine. However, with a large population, the total number of those vaccinated remains under 14%.

"If a third wave happens, we are better equipped, especially for middle-aged and senior citizens due to high vaccination numbers," Niranjan Patil, a doctor in Mumbai, told DW. He added that his private hospital now has "better treatment regiments and care strategies" in addition to improved infrastructure.

"However, we must be better prepared for the unvaccinated, and for pediatric care," he said.

Both Maharashtra and Kerala have high inoculation numbers, with Maharashtra being among the top states in the number of adults who have received both doses.

But new variants are still causing some concern among health experts.

Authorities are collecting more data to decide whether to provide booster shots, as some countries have done.

No lockdowns planned

Maharashtra and Kerala state authorities have so far ruled out the need for another lockdown.

A few restrictions and curfews are still in place, but another lockdown could also be risky for the country’s economy.

"I don’t think there will be need for another lockdown," John told DW.

"Kerala’s healthcare system is able to manage the current spread which has relatively less hospitalizations largely owing to the increased vaccine uptake in Kerala. In Maharashtra too, there is no sign of a rise in cases and a lockdown is out of question," he said.

North-south divide

COVID cases have relatively remained lower in the rest of India. Studies show a north-south divide between Maharashtra and the rest of the southern states having a high caseload, and northern states seeing declining numbers.

Some health experts have attributed this to a higher rate of testing and tracking in these states.

The World Health Organization (WHO)’s chief scientist Soumya Swaminathan said India appears to have reached an endemic stage, where the population learns to live with the virus.

"Because of the size of India and heterogeneity of population and immunity status in different parts of the country in different pockets, it is very feasible that the situation may continue like this with ups and downs in different parts of the country," she said in an interview.

"Particularly where there is a more susceptible population, those groups who were perhaps less affected by first and second waves, or areas with low levels of vaccine coverage could see peaks and troughs for the next several months," she added.
