Bomb scare on Delhi-Kanpur trains,Shatabdi halted at Ghaziabad

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, Jun 18: The Delhi High Court Thursday asked the Delhi Police to file status report on a plea by Jamia Coordination Committee member Safoora Zargar, who was arrested under the anti-terror law --UAPA -- seeking bail in a case related to communal violence in northeast Delhi during protests against the Citizenship Amendment Act in February.

Zargar, M Phil student of Jamia Millia Islamia University, is more than four months pregnant.

Justice Rajiv Shakdher issued notice to the police and asked it to file a status report on the bail plea.

The high court listed the matter for further hearing on June 22.

Zargar, who was arrested by the Special Cell of Delhi Police on April 10, has challenged the June 4 order of the trial court denying her bail in the case.

The trial court, in its order, had said “when you choose to play with embers, you cannot blame the wind to have carried the spark a bit too far and spread the fire.”

It had said that during the course of investigation a larger conspiracy was discernible and if there was prima evidence of conspiracy, acts and statements made by any one of the conspirators, it is admissible against all.

The court had said that even if there was no direct act of violence attributable to the accused (Zargar), she cannot shy away from her liability under the provisions of the Unlawful Activities (Prevention) Act (UAPA).

However, the trial court had asked the concerned jail superintendent to provide adequate medical aid and the assistance to Zargar.

The police had earlier claimed that Zargar allegedly blocked a road near Jaffrabad metro station during the anti-CAA protests and instigated people that led to the riots in the area.

It further claimed that she was allegedly part of the “premediated conspiracy” to incite communal riots in northeast Delhi in February.

Communal clashes had broken out in northeast Delhi on February 24 after violence between citizenship law supporters and protesters spiralled out of control leaving at least 53 people dead and scores injured.

New Delhi, Jan 17: Airports in Srinagar and Jammu are to be “immediately” brought under the security cover of the CISF in view of the arrest of DSP Davinder Singh, a Jammu and Kashmir government order has said.

The two sensitive airports are to be “handed over” to the CISF by January 31, the order of the Jammu and Kashmir Home Department to the Director General of Police (DGP) said.

“This issue (CISF security at Srinagar and Jammu airports) has acquired immediacy in view of the recent developments relating to the arrest of Davinder Singh, DSP airport security, for trying to assist militants to travel to other parts of the country,” the order issued on Wednesday said.

Police had arrested Singh, a deputy superintendent of police, at Mir Bazar in Jammu and Kashmir’s Kulgam district on Saturday, along with Hizbul Mujahideen terrorists Naveed Baba and Altaf, besides a lawyer who was operating as an overground worker for terror outfits.

The two airports are guarded by the CRPF and the J-K Police at present.

The Union government had last year decided that the Central Industrial Security Force (CISF) will be handed over security of these two airports along with the one in Leh in view of their sensitive and strategic location and the threats it faced related to possible terrorist and hijack attempts.

CISF is the national civil aviation security force and at present it guards 61 airports including the ones at Delhi and Mumbai.

News agency had on January 13 reported that the Union home ministry sanctioned about 800 personnel to the CISF in order to take over security duties at the three airports of the newly created Union Territories of Jammu and Kashmir and Ladakh.

As per the original plan, the CISF was to take over Jammu airport by next month and the Srinagar and Leh airports after the spell of severe cold ends.

However, officials said, keeping in mind the arrest of the DSP and his alleged links, the latest order has been issued which also directs the J-K Police to make arrangements for accommodation, transport and other logistical requirements of the armed contingent of the CISF on a quick basis.

Once inducted at the most-sensitive Srinagar airport, the CISF will secure access control at both city and air side (tarmac area) while the CRPF will be responsible for securing the outer periphery. At the Jammu airport, the peripheral security duties will be rendered by the JK Police.

An assortment of surveillance and security gadgets like CCTVs, observation monitors, hand-held metal detectors, bullet-proof patrol vehicles and bomb detection and disposal equipment are also being provided by the airport operator, the Airports Authority of India (AAI), to the CISF.

The Union government sometime back made it clear that CISF will be the only civil airports guarding force and all such facilities in the country will be gradually brought under its command to bolster aviation security and tighten anti-terror and anti-hijack protocols.
