COVID: India is 'at a critical juncture,' says WHO chief scientist

Soumya Swaminathan, chief scientist at the World Health Organization, tells DW that India is at a very fragile and difficult stage in the pandemic. The WHO is concerned as the number of cases is rising significantly.

India recorded 362,727 new COVID-19 infections and 4,120 deaths in the past 24 hours, marking the second straight day in which the country's virus-related deaths exceeded the 4,000 mark.

The surge in cases has overwhelmed the nation's underinvested and dilapidated public health infrastructure, with many states suffering from acute shortages of medical oxygen, essential drugs, beds, health workers and vaccines, among other vital supplies.

The spread of the virus has become rampant in rural areas where cases can go unreported due to a lack of testing.

The rise in infections has been accompanied by a slowdown in vaccinations, even though Prime Minister Narendra Modi announced that vaccinations would be open to all adults from May 1.

In an interview with DW, the World Health Organization's chief scientist Soumya Swaminathan said the spread of infections in rural areas, where the capacity of the public health system to sustain the pressure remains weak, is a cause for concern.

DW: India has been recording

hundreds of thousands of new infections every day and the death toll is on the rise. How do you view the current situation in the country?

Soumya Swaminathan: For the past few days, India has been reporting over 300,000 fresh cases daily. The number of deaths daily has also crossed the 4,000 mark. Infections and deaths continue to grow in many parts of the country.

While shortages of oxygen are being reported, some hospitals and ICUs are operating at full capacity, and therefore unable to admit some patients.

The situation in India and in other countries in the region, where the number of cases is rising significantly, is of great concern to the WHO.

Cases are on the rise in other parts of the world, too, and I think we're at a very fragile and difficult state in this pandemic, where many countries have loosened the public health measures and restrictions that have

been put in place in 2020.

People have gotten back to normal lives, believing that vaccinations would solve the problem. But new virus variants have emerged as the virus is evolving to become more transmissible and more effective.

We have seen epidemiological models which predict that many more people will die of COVID-19 in the near future. The Institute for Health Metrics and Evaluation at the University of Washington estimates that India could potentially see 1 million deaths by August 1.

We are at a critical juncture — we need to be very vigilant and proactive in order to contain the situation, and to change the prediction of future scenarios.

Scenarios depend on many factors, and factors can change. So, it is up to us to change them and to not let the prediction become true.

What do you think are the factors that have led to this surge?

We have seen this happen time and again in different countries. The virus is initially transmitting within a community at relatively low levels.

This can be invisible for quite some time, but it is happening and — unless there is close monitoring of surveillance data — it will gradually increase and reach a point where it has taken off and is transmitting at an accelerated pace, which is exceedingly difficult to stop without applying very stringent measures.

This virus can take off when it finds an opportunity.

At this time, nobody can know for certain what the exact cause of the current surge in India is, but it is likely a combination of factors at play. This includes relaxing of personal protective measures, mass gatherings and the circulation of more contagious variants while vaccine coverage is still low.

We need to jointly focus on filling the gaps in essential medical supplies and hospital capacities, on taking the heat out of the widespread transmission and on saving lives.

Is the "double mutant" variant rst detected in India a major factor in causing the current wave?

Let's call this variant of SARS-CoV-2 — the virus that causes COVID-19 — by what it is, the B.1.617 variant. "Double mutant" sounds scary and we do not want it to be known as the "Indian variant" either.

Currently, several variants are

circulating in India, including the three variants of concern (VOC) — the B.1.117 variant (first detected in the UK), the B.1.351 (first detected in South Africa) and the P.1 variant (detected in Brazil). Newer variants have also been detected in India, such as the B.1.617 variant. While studies are ongoing, there is some evidence that these variants are more contagious.

The WHO has classified the variant B.1.617 as a variant of concern owing to evidence of increased transmissibility.

But for now, the relative contribution of this variant in the rapid increase of cases in India remains unclear.

Nevertheless, based on what we know so far, vaccines, diagnostics and therapeutics continue to be effective against this variant.

How do you see this current surge play out in terms of when it might peak and then taper o ?

We cannot predict when this will be, but we do know the pandemic can be brought under control.

Today the focus needs to be
