New Delhi, Apr 24: The trajectory of COVID-19 cases could have plateaued and might even fall for some weeks after the lockdown is lifted but India is likely to see a second wave in late July or August with a surge in the number of cases during the monsoon, say scientists.

The timing of the peak will depend on how India is able to control physical distancing and on the level of infection spreads after restrictions are relaxed, they said.

It looks apparent that the trajectory of daily new cases has reached a plateau and eventually it will take a downward fall, maybe for some weeks or even months, Samit Bhattacharya, associate professor at the Department of Mathematics, Shiv Nadar University, said.

Still, we may get a surge of new cases of the same coronavirus and this will be considered a second wave, Bhattacharya explained.

The second epidemic may come back in late July or August in the monsoon, although the peak timing will depend on how we control social distancing during that time, he said.

Rajesh Sundaresan, professor at Bengaluru's Indian Institute of Science (IISc), agreed.

“Once we return to normal activity levels, there is a chance that infection may begin to rise again. China is seeing this to some extent post easing of some restrictions on travel,” Sundaresan, corresponding author of a working paper by researchers at IISc and the Tata Institute of Fundamental Research (TIFR) in Mumbai, said.

On March 25, when the number of coronavirus cases was 618 with 13 deaths, the government announced a nationwide lockdown that was later extended to May 3.

On Friday, the death toll due to COVID-19 rose to 718 and the number of cases to 23,077, according to the Union Health Ministry.

In good news, officials said this week that the doubling rate of cases has slowed down in the period, going from 3.4 days before lockdown to 7.5 days, with 18 states doing better than the national average. The recovery rate has also almost doubled in the last 10 days.

"Looking at the new cases in the past few days, it seems the growth of new daily infection is much slower than earlier. This apparently indicates that we might have reached at the plateau of the growth curve, Bhattacharya said.

He noted that recent studies in China and Europe observed that the infection might relapse in those people who have already recovered from earlier phases.

So, there is no evidence that the earlier infection may help acquire immunity against the second infection. And in that way, the entire population may be vulnerable to the second wave to some extent, said the scientist.

In their study unveiled this week, IISc and TIFR researchers analysed the impact of strategies such as case isolation, home quarantine, social distancing and various post-lockdown restrictions on COVID-19 that might remain in force for some time.

The study modelled on Bengaluru and Mumbai suggests the infection is likely to have a second wave and the public health threat will remain, unless steps are taken to aggressively trace, localise, isolate the cases, and prevent influx of new infections.

The new levels and the peaking times for healthcare demand depend on the levels of infection spreads in each city at the time of relaxation of restrictions, they said.

The lockdown is currently upon us. It has given us valuable time. Let us test, trace, quarantine, isolate, practice better hygiene, search for a vaccine, etc. We should do these anyway, and these are being done. When and how to lift the lockdown is going to be a difficult decision to make, said Sundaresan.

It's clear that it's going to be phased. What our team is focusing on is to come up with tools to help the decision makers assess the public health impact of various choices, he said.

According to the experts, infectious diseases spread via contact between infectious and susceptible people. In the absence of any control measures, an outbreak will grow as long as the average number of people infected by each infectious person is more than one.

Once enough people are immune there will be fewer people susceptible to the infection and the outbreak will die.

However, when an outbreak is brought under control by social distancing and other interventions, it is possible only a small proportion of the population will have been infected and gained immunity, they said.

This means enough susceptible people may remain to fuel a second wave if controls are relaxed and infection is reintroduced.

Until the vaccine comes on the market, we have to remain alert Once sporadic cases occur here and there in the country, we immediately need to implement quarantine or social distancing locally for the people in that region, and also need to perform tests to identify positive cases irrespective of showing symptoms, Bhattacharya explained.

Note that these monsoon months are also flu season in many places of India. So, we should not ignore the early signs of the flu symptoms. Irrespective of symptoms, we need to increase tests in the hotspots to identify people and contain the surge, he said.

Sundaresan added that the timeline for a second wave will depend on a lot of circumstances which may change as the time passes.

Significant testing may have been underway, there may be behavioural changes with people becoming more careful about their hygiene, wearing masks may become more common, etc. All these responses may help restrict the second wave, he said.

A study published in The Lancet journal earlier this month modelled the potential adverse consequences of premature relaxation of interventions, and found it might lead to a second wave of infections.

The finding is critical to governments globally, because it warns against premature relaxation of strict interventions, the researchers said.

While interventions to control the spread of SARS-CoV-2 are in place, countries will need to work toward returning to normalcy; thus, knowledge of the effect of each intervention is urgently required, they said in the study.

According to a recent analysis by the Harvard Chan School of Public Health, the best strategy to ease the critical care burden and loss of life from COVID-19 might be on-again, off-again social distancing.

In the absence of such interventions, surveillance and intermittent distancing may need to be maintained into 2022, which would present a substantial social and economic burden, the researchers wrote.p

New Delhi, Feb 24: They hail from vastly different backgrounds — Donald Trump is the son of a property tycoon while Narendra Modi is a descendant of a poor tea-seller.

Yet the two teetotallers, loved by right-wing nationalists in their home countries, share striking similarities that have seen them forge a close personal bond, analysts say.

Ahead of the American leader's first official visit to India, which begins in Modi's home state of Gujarat on Monday, the world's biggest democracy has gone out of its way to showcase the chemistry between them.

In Gujarat's capital Ahmedabad, large billboards with the words "two dynamic personalities, one momentous occasion" and "two strong nations, one great friendship" have gone up across the city.

"There's a lot that Trump and Modi share in common, and not surprisingly these convergences have translated into a warm chemistry between the two," Michael Kugelman of the Washington-based Wilson Center said.

"Personality politics are a major part of international diplomacy today. The idea of closed-door dialogue between top leaders has often taken a backseat to very public and spectacle-laden summitry."

Since assuming the top political office in their respective countries — Modi in 2014 and Trump in 2017 — the two men have been regularly compared to each other.

Trump, 73, and Modi, 69, both command crowds of adoring flag-waving supporters at rallies. A virtual cult of personality has emerged around them, with their faces and names at the centre of their political parties' campaigns.

A focus of Trump's administration has been his crackdown on migrants, including a travel ban that affects several Muslim-majority nations, among others, while critics charge that Modi has sought to differentiate Muslims from other immigrants through a contentious citizenship law that has sparked protests.

Both promote their countries' nationalist and trade protectionist movements — Trump with his "America First" clarion call and Modi with his "Make in India" mantra.

And while they head the world's largest democracies, critics have described the pair as part of a global club of strongmen that includes Russia's Vladimir Putin and Brazil's Jair Bolsonaro.

"There are many qualities that Trump and Modi share — a love for political grandstanding and an unshakable conviction that they can achieve the best solutions or deals," former Indian diplomat Rakesh Sood said.

Modi and Trump have sought to use their friendship to forge closer bonds between the two nations, even as they grapple with ongoing tensions over trade and defence.

Despite sharing many similarities in style and substance, analysts say there are some notable differences between the pair.

Modi is an insider who rose through the ranks of the Bharatiya Janata Party after starting out as a cadre in Rashtriya Swayamsevak Sangh.

Trump is a businessman and a political outsider who has in some sense taken over the Republican Party.

"Modi is a more conventional leader than is Trump in that he hasn't sought to revolutionise the office he holds in the way that Trump has," said Kugelman, a longtime observer of South Asian politics.

He added that genuine personal connections between leaders of both countries have helped to grow the partnership.

"George Bush and Manmohan Singh, Barack Obama and Singh, Obama and Modi, now Modi and Trump — there has been a strong chemistry in all these pairings that has clearly helped the relationship move forward," he added.

Trump has also stood by the Indian leader during controversial decisions, including his revocation of autonomy for Kashmir and his order for jets to enter Pakistani territory following a suicide bombing.

Analysts said the leaders would use the visit to bolster their image with voters.

A mega "Namaste Trump" rally in Ahmedabad on Monday will be modelled after the "Howdy, Modi" Houston extravaganza last year when the Indian leader visited the US and the two leaders appeared before tens of thousands of Indian-Americans at a football stadium.

"The success of this visit... will have a positive impact on his (Trump's) re-election campaign and the people of Indian origin who are voters in the US — a majority of them are from Gujarat," former Indian diplomat Surendra Kumar said.

"On the Indian side, the fact that Prime Minister Modi... (shares) such warmth, bonhomie and informality with the most powerful man on Earth adds to his stature... as well as with hardcore supporters."
