UP Legislative Council chief’s son strangled to death by MOTHER

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

Mumbai, Jan 10: India’s oil demand growth is set to overtake China by mid-2020s, priming the country for more refinery investment but making it more vulnerable to supply disruption in the Middle East, the International Energy Agency (IEA) said on Friday.

India’s oil demand is expected to reach 6 million barrels per day (bpd) by 2024 from 4.4 million bpd in 2017, but its domestic production is expected to rise only marginally, making the country more reliant on crude imports and more vulnerable to supply disruption in the Middle East, the agency said.

China’s demand growth is likely to be slightly lower than that of India by the mid-2020s, as per IEA’s China estimates given in November, but the gap would slowly become bigger thereafter.

“Indian economy is and will become even more exposed to risks of supply disruptions, geopolitical uncertainties and the volatility of oil prices,” the IEA said in a report on India’s energy policies.

Brent crude prices topped USD 70 a barrel on rising geopolitical tensions in the Middle East, putting pressure on emerging markets such as India. Like the rest of Asia, India is highly dependent on Middle East oil supplies with Iraq being its largest crude supplier.

India, which ranks No 3 in terms of global oil consumption after China and the United States, ships in over 80 per cent of its oil needs, of which 65 per cent is from the Middle East through the Strait of Hormuz, the IEA said.

The IEA, which coordinates release of strategic petroleum reserves (SPR) among developed countries in times of emergency, said it is important for India to expand its reserves.

REFINERY INVESTMENTS

India is the world’s fourth largest oil refiner and a net exporter of refined fuel, mainly gasoline and diesel.

India has drawn plans to lift its refining capacity to about 8 million bpd by 2025 from the current about 5 million bpd.

The IEA, however, forecasts India’s refining capacity to rise to 5.7 million bpd by 2024.

This would make “India a very attractive market for refinery investment,” IEA said.

Drawn to India’s higher fuel demand potential, global oil majors like Saudi Aramco, BP, Abu Dhabi National Oil Co and Total are looking at investing in India’s oil sector.

Saudi Aramco and ADNOC aim to own a 50 per cent stake in a planned 1.2-million bpd refinery in western Maharashtra state, for which land is yet to be acquired.

New Delhi, Jun 25: The Supreme Court on Thursday asked the Centre and the CBSE to issue fresh notification in connection with Class 12 exams, clarifying the option between internal assessment and exams later.

The observation from the top court after it was informed that the CBSE has decided to cancel the remaining board exams for Class 10 and Class 12.

A bench comprising Justices AM Khanwilkar, Dinesh Maheshwari and Sanjiv Khanna asked the Centre to clarify the issue of taking the option between internal assessment and exams later.

"Clarify the date of results," said the bench, noting that the CBSE will have to submit a fresh draft notification cancelling class 12 Board exams and affidavit on Friday morning, before the top court continues to hear the matter again at 10.30 a.m.

The apex court also sought clarity on the beginning of the new academic year.

It told Solicitor General Tushar Mehta, representing the Centre, that the CBSE is willing to conduct exams when the situation is conducive, but this may vary from state to state. "Will the decision be taken by a central authority or will the state government take the decision? How are you going to deal with that situation?"

Mehta replied that the decision must be taken according to the situation. To this, the bench said should not the solution be pan-India?

"You have not said when you will decide on this issue, and when you will take stock of these things. Some time frame will have to be given," noted the bench.

Continuing its queries, the bench said: "What about state regional board exams... the CBSE does not hold all the exams. The state Board is also there."

Mehta replied that the instructions from the controller of examinations are that exams are controlled centrally. "State boards assist the CBSE," he replied.

The bench observed that the government should modify the draft notification and include the state board issue. "Clear the stand that decision will be taken at the central level and not at the state level... other courses will have to be delayed till CBSE exam results come out," it said.

Mehta replied the assessment results will be published now, and if a student wants to opt to give the exam, then that will be conducted later. The top court asked Mehta to bring this on record and redraft the notification.
