Supreme Court dismisses plea of sacked BSF jawan Tej Bahadur Yadav

New Delhi, May 26: With India now in the bracket of top 10 nations worst hit by the novel coronavirus, experts have attributed the surge in cases to easing of travel restrictions and movement of migrants besides enhanced testing capacity.

According to AIIMS Director, Randeep Guleria, the present rise in cases has been reported predominantly from hotspot areas but there is a possibility of further rise in the number of COVID-19 cases in the coming few days due to increased travel.

"Those who are asymptomatic or are in presymptomatic stage will pass through screening mechanisms and may reach areas where there have been minimal or less cases," Guleria said.

He said there was a need for more intense surveillance and monitoring in areas where migrants have returned to contain the spread of the disease.

If proper social distancing and hand hygiene is not maintained at a time when people are out on roads, the coronavirus infection will transmit much faster, he said.

Guleria also noted that testing capacity has been significantly ramped up which is reflecting in the increasing number of cases being detected.

Commenting on the partial resumption of rail and road transport services and migrants returning to their native places, Dr Chandrakant S Pandav, former president of the Indian Public Health Association and Indian Association of Preventive and social medicine, said the floodgates have been opened.

"This is a classic case of creating an enabling environment for coronavirus to spread like wildfire. In the coming few days, the number will rise dramatically. While it is true that lockdown cannot go on forever, the opening up should have been in a measured, calibrated and informed manner," he said.

"Travelling leads to spread of the infection. Now, the government will have to ensure even stronger surveillance to curb the infection but if that will be done is something to be observed," he said.

The death toll due to COVID-19 rose to 4,167 and the number of cases climbed to 1, 45,380 in the country, registering an increase of 146 deaths and 6,535 cases since Monday 8 am, according to the Union Health Ministry.

Dr K K Aggarwal, President of the Confederation of Medical Association of Asia and Oceania (CMAAO), and former IMA President, said there will be a further surge in cases in the coming days if migration continues without any proper social distancing.

"Within the next ten days, the cases will cross two lakh. The very fact that number of cases was rising before the end of the third lockdown and continuing during the fourth lockdown means that people are not following physical distancing as required," he said.

"Even in the last week of May when the temperature is very high, the rising number of cases would mean that human-to-human transmission is more important than surface-to-human transmission. Normally in heat the surface-to-human transmission should have reduced the new cases by half which has not happened," Aggarwal said.

However, Professor K Srinath Reddy, president of the Public Health Foundation of India, said an increase in the number of cases reflects both an increase in testing rates and an increase in spread.

"What we need to see is the number of new tests performed per day and the number of new cases that were identified from them. That gives a better idea of the rate of spread than the total number of new cases alone.

"We also have to see if the testing criteria has remained the same between the two periods of comparison.We may open up gradually but will have to continue case detection, contact tracing and follow personal protection measures as vigorously as possible," he added.

A total of 31,26,119 samples have been tested as on May 26, 9 am and 92,528 samples have been tested in the last 24 hours, ICMR officials said.

India is the tenth most affected nation by the pandemic after the US, Russia, UK, Spain, Italy, Brazil, Germany, Turkey and France, as per the John Hopkins University data.

The country has recorded 6,088, 6,654, 6,767 and 6977 cases on May 22, 23, 24 and 25 respectively. Also, the number of RT-PCR tests for detection of COVID-19 in the country crossed the 30-lakh mark on Monday.

The first two phases of the lockdown led to 14-29 lakh COVID-19 cases being averted, while the number of lives saved in that period was between 37,000 and 78,000, the government said last Friday, citing various studies, and asserted that the unprecedented shutdown has paid "rich dividends" in the fight against the pandemic.

New Delhi, Jul 6: The Indian Academy of Sciences, a Bengaluru-based body of scientists, has said the Indian Council for Medical Research's (ICMR) target to launch a coronavirus vaccine by August 15 is "unfeasible" and "unrealistic".

The IASc said while there is an unquestioned urgent need, vaccine development for use in humans requires scientifically executed clinical trials in a phased manner.

While administrative approvals can be expedited, the "scientific processes of experimentation and data collection have a natural time span that cannot be hastened without compromising standards of scientific rigour", the IASc said in a statement.

In its statement, the IASc referred to the ICMR's letter which states that "it is envisaged to launch the vaccine for public health use latest by 15th August 2020 after completion of all clinical trials".

The ICMR and Bharat Biotech India Limited, a private pharmaceutical company, are jointly developing the vaccine against the novel coronavirus -- SARS-CoV-2.

The IASc welcomes the exciting development of a candidate vaccine and wishes that the vaccine is quickly made available for public use, the statement said.

"However, as a body of scientists including many who are engaged in vaccine development IASc strongly believes that the announced timeline is unfeasible. This timeline has raised unrealistic hope and expectations in the minds of our citizens," it said.

Aiming to launch an indigenous COVID-19 vaccine by August 15, the ICMR had written to select medical institutions and hospitals to fast-track clinical trial approvals for the vaccine candidate, COVAXIN.

Experts have also cautioned against rushing the process for developing a COVID-19 vaccine and stressed that it is not in accordance with the globally accepted norms to fast-track vaccine development for diseases of pandemic potential.

The IASc said trials for a vaccine involve evaluation of safety (Phase 1 trial), efficacy and side effects at different dose levels (Phase 2 trial), and confirmation of safety and efficacy in thousands of healthy people (Phase 3 trial) before its release for public use.

Clinical trials for a candidate vaccine require participation of healthy human volunteers. Therefore, many ethical and regulatory approvals need to be obtained prior to the initiation of the trials, it added.

The IASc said the immune responses usually take several weeks to develop and relevant data should not be collected earlier.

"Moreover, data collected in one phase must be adequately analysed before the next phase can be initiated. If the data of any phase are unacceptable then the clinical trial is required to be immediately aborted," it said.

For example, if the data collected from Phase 1 of the clinical trial show that the vaccine is not adequately safe, then Phase 2 cannot be initiated and the candidate vaccine must be discarded.

For these reasons, the Indian Academy of Sciences believes that the announced timeline is "unreasonable and without precedent", the statement said.

"The Academy strongly believes that any hasty solution that may compromise rigorous scientific processes and standards will likely have long-term adverse impacts of unforeseen magnitude on citizens of India," it said.

Mar 16: A fourth batch of 53 Indians returned to India from Iran on Monday, taking the total number of people evacuated from the coronavirus-hit country to 389.

This comes a day after over 230 Indians were brought back from Iran to New Delhi and quarantined at the Indian Army Wellness Centre in Jaisalmer, the third batch to be evacuated from that country.

"Fourth batch of 53 Indians - 52 students and a teacher - has arrived from Tehran and Shiraz, Iran. With this, a total of 389 Indians have returned to India from Iran. Thank the efforts of the team @India_in_Iran and Iranian authorities," Jaishankar tweeted.

The Indians came in a Mahan Air flight that landed at the Delhi airport at around 3 am, officials said, adding that they were later taken to Jaisalmer in an Air India flight for being quarantined.

The first batch of 58 Indian pilgrims were brought back from Iran last Tuesday and the second group of 44 Indian pilgrim arrived from there on Friday.

Iran is one of the worst-affected countries by the coronavirus outbreak and the government has been working to bring back Indians stranded there. Over 700 people have died from the disease in Iran and nearly 14,000 cases have been detected.

Jaishankar had told Rajya Sabha last week that the government was focusing on evacuating Indians stranded in Iran and Italy as these countries are facing an "extreme situation".
