Modi,Sharif finally greet after cold vibes

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 29: India’s economy expanded at its slowest pace in more than six years in the last three months of 2019, with analysts predicting further deceleration as the global Covid 19 coronavirus outbreak stifles growth in Asia’s third-largest economy.

The gross domestic product (GDP) data released yesterday showed government spending, private investment and exports slowing down, while there is a slight upturn in consumer spending and improvement in rural demand lent support.

The quarterly figure of 4.7% growth matched the consensus in a Reuters poll of analysts but was below a revised - and greatly increased - 5.1% rate for the previous quarter.

The central bank has warned that downside risks to global growth have increased as a result of the coronavirus epidemic, the full effects of which are still unfolding.

Prime minister Narendra Modi’s government has taken several steps to bolster economic growth, including a privatisation push and increased state spending, after cutting corporate tax rates last September.

In its annual budget presented this month, the government estimated that annual economic growth in the financial year to March 31 would be 5%, its lowest for last 11 years.

Modi’s government is targeting a slight recovery in growth to 6% for 2020/21, still far below the level needed to generate jobs for millions of young Indians entering the labour market each month.

The annual GDP figure for the September quarter was ramped up from an earlier estimate of 4.5%, while the April-June reading was similarly lifted to 5.6% from 5%, data released by the Ministry of Statistics showed on Friday.

Capital Investment Drop

In the December quarter, private investment grew 5.9%, up from 5.6% in the previous quarter, while government spending rose by 11.8%, against 13.2% in the previous three months.

However, corporate capital investment contracted by 5.2% after a 4.1% decline in the previous quarter, indicating that interest rate cuts by the central bank have failed to encourage new investment. Manufacturing, meanwhile, contracted by 0.2%.

“It appears growth slowdown is not just cyclical but more entrenched with consumption secularly joining the slowdown bandwagon even as the investment story continues to languish,” said Madhavi Arora of Edelweiss Securities in Mumbai.

Many economists said that the government stimulus could take four to six quarters of time before lifting the economy and the impact of those efforts could be outweighed by the global fallout from the coronavirus epidemic that began in China.

“The coronavirus remains the critical risk as India depends on China for both demand and supply of inputs,” said Abheek Barua, chief economist at HDFC Bank.

Indian shares sank on Friday for a sixth session running, capping their worst week in more than a decade. The NSE Nifty 50 index shed 7.3% over the week, while the Sensex dropped 6.8%, the worst weekly declines since the 2008-09 financial crisis.

Separately, India’s infrastructure output rose 2.2% year on year in January, data showed on Friday.

A spike in inflation to a more than 5-1/2 year high of 7.59% in January is expected to make the RBI hold off from further cuts to interest rates for now, while keeping its monetary stance accommodative.

New Delhi, Mar 27: Cabinet Secretary Rajiv Gauba has asked states to urgently strengthen the surveillance of international travellers who entered the country before the lockdown as there appeared to be a "gap" between the actual monitoring for COVID-19 and the total arrivals.

In a letter to chief secretaries of all States and Union Territories, Gauba said such a gap in monitoring of international passengers for coronavirus "may seriously jeopardise the efforts to contain the spread of COVID-19", given that many amongst the persons who have tested positive so far in India have history of international travel.

"As you are aware, we initiated screening of international incoming passengers at the airports with effect from January 18, 2020. I have been informed that up to March 23, 2020, cumulatively, Bureau Of Immigration has shared details of more than 15 lakh incoming international passengers with the States/UTs for monitoring for COVID-19.

"However, there appears to be a gap between the number of international passengers who need to be monitored by the States/UTs and the actual number of passengers being monitored," Gauba said in his letter.

The government had started monitoring of all international passengers who have arrived in India in last two months in the wake of the coronavirus outbreak.

Gauba said,"it is important that all international passengers are put under close surveillance to prevent the spread of the epidemic."

He said the Ministry of Health and Family Welfare (MoHFW) has repeatedly emphasised the importance of monitoring, and requested the states and UTs to take immediate steps in this regard.

"I would, therefore, like to request you to ensure that concerted and sustained action is taken urgently to put such passengers under surveillance immediately as per MoHFW guidelines," he said.

The cabinet secretary also urged the chief secretaries to actively involve the district authorities in this effort.The screening of international incoming passengers at airports was done from January 18 in a phased manner.

The Central and state governments have unleashed unprecedented and extraordinary measures to contain the spread of the fast-spreading coronavirus, which has already infected more than 700 people in the country and claimed at least 17 lives.

A nationwide lockdown was also announced by Prime Minister Narendra Modi on Tuesday for 21 days.
