Tourist killed in Kashmir stone pelting; CM says her head hangs in shame

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

Kashmir, Mar 3: Four days after the National Investigation Agency made a major breakthrough in the Pulwama terror attack case over a year after the bombing, arresting one person who had sheltered the suicide bomber Adil Ahmad Dar, the NIA on Tuesday arrested two more people in the case - a father-daughter duo - who had also provided shelter to the bomber, officials said.

The NIA also claimed that the video of the suicide bomber was also recorded at their residence and released by the Jaish-e-Mohammad (JeM) terror group from Pakistan after the attack. An NIA spokesperson in Delhi said: "Two more persons have been arrested by the agency in the Pulwama terror attack case and they have been identified as Insha Jan, 23, and her father Tariq Ahmed Shah, 50, who works as a tipper driver."

The official said that the father-daughter duo have been arrested from Hakripora area in Pulwama for their involvement in the attack. The two were arrested on early Tuesday morning after senior officials of the NIA raided their house on Monday night.

A senior NIA official related to the probe told IANS: "The video of Dar, who attacked the CRPF convoy, was recorded at the home of the duo. And the same video was released soon after the Pulwama terror attack by the JeM terrorists from a Pakistani IP address."

He said, "The video was shared by them to their handlers in Pakistan."

The spokesperson further claimed that during the probe Tariq Ahmed Shah disclosed that his house in Hakripora area was used by Dar, Mohammad Umar Farooq, a Pakistani terrorist and IED maker, Kamran - another Pakistani terrorist (both were later killed in encounters with security forces), Sameer Ahmed Dar, a Jaish-e-Mohammad terrorist from Pulwama and Mohammad Ismail aka Ibrahim, a Pakistani terrorist.

The spokesperson said that Shah facilitated all the terrorists at his house for sheltering and for planning of the heinous attack on the CRPF convoy. He said Jan, daughter of Shah, facilitated the terrorists at their home and provided food and other logistics during their stay on more than 15 occasions for two to four days each time, in their house during the year 2018-2019.

"Initial interrogation has revealed that Jan was in constant touch with Farooq and was in communication with him over telephone and other social media applications," the spokesperson said. The fresh arrests of the two accused brings the total number of arrests in the case to three.

The arrests were made on the revelations of Shakir Bashir Magrey, who was arrested by the anti-terror probe agency on February 28. According to senior NIA officials, more arrests will be made in the coming days. Magrey, a resident of Hajibal, Kakapora in Pulwama district of Jammu & Kashmir, is an overground worker (OGW) of the Pakistan-based Jaish-e-Mohammad (JeM).

According to agency sources, Magrey allegedly provided shelter and other logistical assistance to the Pulwama suicide bomber. He was sent to 15 days' NIA custody by a special NIA court in Jammu & Kashmir on Friday. During interrogation, Magrey revealed that he had harboured Dar and Pakistan-based terrorist Mohammad Umar Farooq in his house from late 2018 till the attack in February 2019 and assisted them in the preparation of the Improvised Explosive Device (IED). His shop is located near Lethpora bridge, and as advised by Mohammad Umar, he started conducting reconnaissance of the movement of CRPF convoys on Jammu-Srinagar Highway in January 2019, and informed Mohammad Umar and Adil Ahmad Dar about it.

Magrey was also involved in modifying the Maruti Eeco car and fitting the IED into it in early February, 2019 and was introduced to Adil Ahmad Dar in mid-2018 by Mohammad Umar and he became a full-time OGW of JeM.

"During his initial interrogation, he disclosed that on several occasions, he collected and delivered arms, ammunition, cash and explosive material to JeM terrorists, including those involved in the Pulwama attack," the agency had said on February 28.

"During investigation, the make, model and number of the car used in the attack was quickly ascertained by NIA to be a Maruti Eeco through forensic examination of the tiny remnants of the car which were found at the spot during extended searches," the agency stated.

"This has been corroborated by accused Shakir Bashir Magrey. The explosives used in the attack were determined to be ammonium nitrate, nitro-glycerin and RDX, through forensic investigation," it said.
