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: India and the US are committed to defend their people from radical islamic terrorism, resolved to significantly expand defence ties and are working on a "fantastic" trade deal, said US President Donald Trump on Monday while asserting that his country "loves" and is "loyal" to India.

Addressing a huge crowd at 'Namaste Trump' event at the Motera stadium here, the US president, accompanied by his wife Melania and Prime Minister Narendra Modi, talked about India's great tradition of embracing individual freedom, rule of law, dignity of every human being and where people worship side-by-side in harmony.

On his maiden visit, Trump, who was welcomed by Modi on his arrival here, said his country will remain a "loyal" friend of India and called the Prime Minister an "exceptional leader" who works day and night for the country.

"India and the US are committed to fight terrorists and their ideology; that is why my government is working with Pakistan to crack down on terror groups," Trump said in the presence of his family -- daughter Ivanka, son-in-law Jared Kushner-- and top brass of his administration.

"The US will always be faithful and loyal friend of India. Thank you for the spectacular welcome," he added.

He also announced that the two countries will firm up defence deals worth USD 3 billion on Tuesday and that the US will become India's premier defence partner.

"India and US have natural and enduring friendship," Trump said to a cheering crowd.

"We are quickly revitalising our alliances all around world," he said.

Trump said both countries are working on a "fantastic trade" deal, and observed that Modi is a "tough negotiator".

The US president also heaped praises on Modi, saying the Prime Minister is a "living proof" of what an Indian can achieve with hard work as Trump referred to his humble background as a tea-seller, who had a landslide win in the 2019 Lok Sabha polls.

On his part, Modi welcomed Trump to "world's largest democracy" and said a "new history" was being created.

Modi also praised Trump's leadership in containing terrorism.

Trump said as the world's largest economy, India gives hope to all humanity and has become an economic giant.

"There is a difference between a nation that rises by coercion and one that rises by setting its people free -- that is India. India and the US have natural and enduring friendship," he said.

He also touched on India's cultural diversity and riches as he highlighted the success of its blockbuster movies like DDLJ (Dilwale Dulhania Le Jayenge) and Sholay, and its sporting icons like Sachin Tedulkar and Virat Kohli.

He highlighted the boom in the US economy under his presidency and added that India will soon be home to the biggest middle class as it will eliminate extreme poverty in in next 10 years.

On his part, Modi said ties between India and the US are no longer just another partnership but have touched far greater heights.

Welcoming Trump, he said a "new history" is being created.

Visit of President Trump to India with his family shows strong ties between India and the US, said Modi.

New Delhi, Jul 16: A group of 174 Indian nationals, including seven minors, has filed a lawsuit against the recent presidential proclamation on H-1B that would prevent them from entering the United States or a visa would not be issued to them.

Judge Ketanji Brown Jackson at the US District Court in the District of Columbia issued summonses on Wednesday to Secretary of State Mike Pompeo and acting Secretary of Homeland Security Chad F Wolf, along with Labor Secretary Eugene Scalia.

The lawsuit was filed in the US District Court on Tuesday.

"The proclamation 10052's H-1B/H-4 visa ban hurts the United States' economy, separates families and defies the Congress. While the two former points render it unseemly, the latter point renders it unlawful," said the lawsuit filed by lawyer Wasden Banias on behalf of the 174 Indian nationals.

The lawsuit seeks an order declaring the presidential proclamation restriction on issuing new H-1B or H4 visas or admitting new H-1B or H-4 visa holders as unlawful. It also urges the court to compel the Department of State to issue decisions on pending requests for H-1B and H-4 visas.

In his presidential proclamation on June 22, Trump temporarily suspended issuing of H-1B work visas till the end of the year.

"In the administration of our nation's immigration system, we must remain mindful of the impact of foreign workers on the United States labor market, particularly in the current extraordinary environment of high domestic unemployment and depressed demand for labor," said the proclamation issued by Trump.

In his proclamation, Trump said the overall unemployment rate in the United States nearly quadrupled between February and May of 2020 -- producing some of the most extreme unemployment ever recorded by the Bureau of Labor Statistics.

While the May rate of 13.3 per cent reflects a marked decline from April, millions of Americans remain out of work.

The proclamation also extends till year-end his previous executive order that had banned issuance of new green cards of lawful permanent residency. Green Card holders, once admitted pursuant to immigrant visas, are granted "open-market" employment authorisation documents, allowing them immediate eligibility to compete for almost any job in any sector of the economy, Trump said.

Forbes, which first reported the lawsuit filed by the Indian nationals, said the complaint points out that the Congress specified the rules under which H-1B visa holders could work in the US and balanced the interests of US workers and employers.

"The complaint seeks to protect H-1B professionals, including those who have passed the labor certification process and possess approved immigrant petitions. Such individuals are waiting for their priority date to obtain permanent residence, a wait that can take many years for Indian nationals," Forbes reported.

Meanwhile, several lawmakers urged Scalia on Tuesday to reverse the work visa ban.

"Throughout this administration, the president has continued to lament the alleged abuses of the immigration system while failing to address the systemic problems that have persisted and allowed businesses and employers to exploit and underpay immigrant workers, guest workers and American workers," the lawmakers wrote.

"This misguided attempt by the president to scapegoat immigrants for policy failures during the pandemic not only serves to hurt immigrants, but dismisses the true problem of a broken work visa program that is in desperate need of reform," said the letter, which among others was signed by Congressmen Joaquin Castro, Chair of the Congressional Hispanic Caucus; Bobby Scott, Chair of the Education and Labor Committee; Karen Bass, Chair of the Congressional Black Caucus; Judy Chu, Ra l Grijalva, Vicente Gonzalez, Yvette Clarke and Linda S nchez.
