Vilified by Indian Prime Minister Narendra Modi's party for its high COVID-19 cases, Kerala's apparent poor record may actually hold crucial lessons for the country in containing the outbreak as authorities brace for a possible third wave of infections. The opposition-ruled, densely populated southern state is currently reporting the most number of coronavirus cases in the country and accounts for the second-highest national tally - unflattering headline numbers that Modi's Bharatiya Janata Party (BJP) has seized upon as a reflection of bungled local leadership.

However, a Reuters analysis of national and state data, and interviews with epidemiologists and Kerala health authorities paint a different picture. It shows the state's containment measures have helped to catch infections early, allowing authorities to better manage the illness and dramatically lower the death rate - a stark contrast to people dying in carparks and outside hospitals for lack of oxygen and beds in big cities like Delhi at the height of the health crisis a few months earlier. "While the federal government may have its views on rapid antigen tests,

it is important to consider that the state's strategies have by and large succeeded in not just keeping mortality low but also in being able to detect one in six cases compared to one in 33 nationally," said Rajib Dasgupta, head of the Centre of Social Medicine & Community Health at New Delhi's Jawaharlal Nehru University. The efficient detection rate and its population density at more than twice the national average explain the high number of cases in Kerala. All the same, at 0.5%,

Kerala still has the lowest fatality rate among all but one thinly populated state. The national figure is 1.4% and it is 1.3% for the country's most populous state, Uttar Pradesh. The difference comes down to Kerala's reliance on rapid antigen tests to detect and strictly isolate infected people at home, an approach the federal health ministry has sharply criticised but which state officials argue has helped them to better allocate hospital beds and oxygen supplies for those who really need them.

The government-recommended RT-PCR tests are more accurate but take longer to produce results, meaning by the time a positive COVID-19 case is confirmed the infected person is more likely to have developed severe symptoms and passed it on to others in a vicious cycle of more infections and deaths. Kerala's rapid test results allow for early treatment in home isolation which then narrows the virus' path to infections, state officials say. These factors, along with the strained medical resources across much of India, largely explain why the overall national death rate is much higher than in the Communist-run state.

Kerala officials also say a state-run support service that includes phone consultation, provision of drugs and pulse oximeters that detect blood oxygen levels for people recovering at home provide a bulwark in the battle against the disease. Delhi had a similar support structure but it collapsed when cases surged. "We do have a different model and our fatality rate shows our model is on the right track," Kerala Health Minister Veena George told Reuters. But Kerala officials acknowledge that the fast-evolving pandemic can undo even the best thought-out plans unless authorities remain nimble and flexible.
