India reacts strongly to US decision to sell 8 F-16 jets to Pakistan, summons envoy

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, Apr 23: Congress president Sonia Gandhi on Thursday accused the BJP of spreading the virus of communal prejudice and hatred in the country, asserting that "grave damage" is being done to social harmony

Addressing a meeting of the Congress Working Committee, Gandhi said it should worry every Indian and her party will have to work hard to repair this damage.

"Let me also share with you something that should worry each and every one of us as Indians. When we should be tackling the coronavirus unitedly, the BJP continues to spread the virus of communal prejudice and hatred," she said.

"Grave damage is being done to our social harmony. Our party, we will have to work hard to repair that damage," the Congress president added

Former prime minister Manmohan Singh, former Congress president Rahul Gandhi and top Congress leaders attended the meeting through video conference

This is the second time the CWC, the Congress' top decision-making body, is meeting through video-conferencing in the past three weeks ever since the lockdown was enforced to contain the coronavirus threat.

The Congress president said the coronavirus pandemic has increased disturbingly in the past three weeks and called upon the government to increase testing for it

Gandhi said she has written several times to the prime minister since the lockdown was enforced and suggested several measures and constructive cooperation

"Unfortunately, they have been acted upon only partially and in a miserly way. The compassion, large-heartedness and alacrity that should be forthcoming from the central government is conspicuous by its absence," she said

The Congress chief said the focus of the party must continue to be on successfully engaging with health, food security and livelihood issues.

She claimed that around 12 crore people have lost jobs in the first phase of the lockdown and urged the government to provide a relief package for the MSME sector, which accounts for one-third of the GDP

Gandhi called upon the government to provide food and financial security to migrants and jobless stranded at various places and were desperate to reach back home

"We have repeatedly urged PM there is no alternative to testing, tracing and quarantine. Unfortunately, testing still remains low, testing kits still in short supply," she noted

Gandhi said trade, commerce and industry have come to a virtual halt and crores of livelihoods have been destroyed.

"The central government does not appear to have a clear idea on how the situation will be managed after May 3rd. A lockdown of the present nature after that date would be even more devastating," she said

Former prime minister Manmohan said the success of the lockdown will be judged finally on India's ability to tackle COVID-19

He also said the cooperation between the Centre and states was key to success of the country's fight against coronavirus

Singh said it is necessary to focus on a number of issues in the fight against coronavirus

The fight against COVID-19 would very much depend upon the availability of resources, he noted

Rajasthan chief minister Ashok Gehlot said unless the central government comes forward to financially help states, the fight against COVID-19 will get weakened

"Unless there is a big financial package for states, how will normalcy return to states post lockdown," he asked

Chhattisgarh chief minister Bhupesh Baghel said unless the Centre rises to the occasion and provides financial assistance to states, how will the fight against COVID-19 be won

Puducherry chief minister V Narayanasamy said the Union government has not given any assistance to the states

"How will states survive in times of crisis. We are not enemies but have to act and work together," Narayanasamy said at the CWC meet.

Kozhikode, Apr 24: A four-month-old baby girl, who had tested positive for COVID-19 and suffering from congenital heart disease, died in a hospital here in Kerala early Friday after suffering a cardiac arrest, officials said.

This is the third COVID-19 death and the first infant fatality in the state where two elderly people had succumbed to the disease earlier.

The baby was admitted to the Medical College Hospital here on April 21 with history of fever, cough, breathing difficulties and seizure after being treated at two other hospitals and the end came at 6 am, a medical bulletin said.

State Health Minister K K Shailaja said doctors had made maximum efforts to save the life of the child, whose family belonged to Payyanad near Manjeri in Malappuram district.

"Preliminary information which we have is that there has been some primary contact", she told reporters in Thiruvananthapuram.

The protocol for COVID-19 cases would be followed for the baby's last rites, the Minister added.

As of Thursday, the total active COVID-19 cases in the state stood at 129.

The bulletin said on arrival at the hospital on Tuesday the baby was in shock and had respiratory failure.

"She was resuscitated, mechanically ventilated and appropriate antibiotics for pneumonia and supportive measures to correct shock were started", it said adding the baby, however, continued to remain sick.

"Even though there was no history of any high or low risk contact or any epidemiological links as the child comes from SARI (Sever Acute Respiratory infection) criteria, she was admitted to the COVID-ICU and swab was taken and she tested positive", the bulletin said.

Contact tracing of those who had come in contact with the child was in progress.

Mallapuram District Medical Officer (Health) Dr Sakeena K said the child was having severe health issues from its birth itself and was admitted to a private hospital in Manjeri near here with breathing problem.

As her condition worsened, the baby was shifted to another hospital and later to the medical college hospital.

"The baby was having chest deformity and Atrial Septal Defect by birth which developed into severe health issues, the official added.
