India, Israel join hands to develop rapid testing for Covid-19 in under 30 seconds

Kolkata, May 20: Cyclone 'Amphan' lay centred about 240 km south of Digha in West Bengal on Wednesday morning as an extremely severe cyclonic storm, the Met department said here.

The intensity near the centre of the storm was 170 to 180 kmph gusting to 200 kmph, the Met said.

'Amphan' is very likely to move north-northeastwards and cross West Bengal-Bangladesh coast between Digha and Hatiya, close to the Sunderbans during the afternoon to evening of Wednesday with a wind speed of 155 to 165 kmph gusting to 185 kmph as a 'very severe cyclonic storm', the Met department said.

West Bengal has evacuated more than three lakh people to safer places as the cyclonic storm 'Amphan' roared towards the coastal areas of the state, officials said.

The Met department, which has issued an "orange message" for West Bengal, warned of extensive damage in Kolkata, Hooghly, Howrah, South and North 24 Parganas and East Midnapore districts.

The Met department has advised that all establishments and markets remain closed in Kolkata and adjoining areas and movement of people be restricted on May 20.

There is likely to be disruption of rail and road link at several places, uprooting of communication and power poles, extensive damage to all types of 'kutcha' houses and some damage to "old badly managed pucca" structures and potential threat from flying objects, the weatherman warned.

There is also likelihood of extensive damage to standing crops, plantations and orchards and blowing down of palm and coconut trees, the Met said.

The weatherman has advised diversion or suspension of rail and road traffic in the districts which are likely to be affected.

The Eastern Railway (ER) has cancelled the departure of Howrah-New Delhi AC Special Express for Wednesday.

The departure of 02301 Howrah-New Delhi AC Special Express on Wednesday and 02302 New Delhi-Howrah AC Special Express on May 21 would remain cancelled, the ER said.

Wind speed along and off the coastal areas of West Bengal will reach 75 to 85 kmph with gusts up to 95 kmph from Wednesday morning along and off districts of North and South 24 Parganas, East and West Midnapore, Kolkata, Howrah and Hooghly, Regional Met director G K Das said.

"It will gradually increase thereafter becoming 110 to 120 kmph gusting to 130 kmph over West Midnapore, Howrah, Hooghly, Kolkata and wind speed of 155 to 165 kmph gusting to 185 kmph over the districts of North and South 24 Parganas and East Midnapore of West Bengal from the afternoon to night of May 20," he said.

Under its impact rainfall will occur in most places over the districts of Gangetic West Bengal on Wednesday, with heavy to very heavy downpour with extremely heavy rain at a few places in Kolkata, Howrah, East Midnapore, North and South 24 Parganas and Hooghly districts, he said.

"Storm surge of 4 to 5 metres above astronomical tide is likely to inundate low lying areas of South and North 24 Parganas and about 3 to 4 metres over low lying areas of East Midnapore district of West Bengal during the time of landfall," he said.

The Indian Navy has dispatched a diving team for providing assistance to the West Bengal government in relief operations, a Defence official said.

The diving team from Vishakhapatnam has brought specialised equipment along with them which can be used for rescue in case of flooding and have been positioned at the Naval Service Selection Board at Diamond Harbour in South 24 Parganas district, the official said.

New Delhi, May 23: The nationwide lockdown will no longer help India in its fight against COVID-19, and in its place community-driven containment, isolation and quarantine strategies have to be brought into play, leading virologist Shahid Jameel said.

The recipient of Shanti Swarup Bhatnagar Prize for Science and Technology also stressed that testing should be carried out vigorously to identify coronavirus hotspots and isolate those areas.

"Our current testing rate at 1,744 tests per million population is one of the lowest in the world. We should deploy both antibody tests and confirmatory PCR tests. This will tell us about pockets of ongoing infection and past (recovered) infection. This will provide data to open up gradually and let economic activity resume," Jameel told PTI in an interview.

He stressed that testing has to be dynamic to continuously monitor red, orange and green zones and change these based on that data.

About community transmission of COVID-19 in India, Jameel said the country reached that stage long ago.

"We reached community transmission a long time ago. It's just that the health authorities are not admitting it. Even ICMR's own study of SARI (severe acute respiratory illness) showed that about 40 per cent of those who tested positive for SARS-CoV-2 did not have any history of overseas travel or contact to a known case. If this is not community transmission, then what is?" he posed.

Lockdown bought India time in its fight against coronavirus, but continuing it is unlikely to yield any further dividend, Jameel said.

"Instead, community-driven local lockdowns, isolations and quarantines have to come into play. Building trust is most important so that people follow rules. A public health problem cannot be dealt with as a law-and-order problem."

The nationwide lockdown, initially imposed from March 25 to April 14, has been extended thrice and will continue at least till May 31. The virus has claimed 3,720 lives and infected over 1.25 lakh people in the country so far.

Jameel has expertise in the fields of molecular biology, infectious diseases, and biotechnology. He is the CEO of Wellcome Trust/Department of Biotechnology's India Alliance and is best known for extensive research in Hepatitis E virus and HIV.

He said COVID-19 will eventually be controlled through herd immunity, which is acquired in two ways – when a sufficient fraction of the population gets infected and recovers, and with vaccination.

"It is estimated that for SARS-CoV-2 at least 60 per cent of the population would have to be infected and recovered, or vaccinated. This will happen over the course of the next few years," Jameel said.

Herd immunity is reached when the majority of a population becomes immune to an infectious disease, either because they have become infected and recovered, or through vaccination. When that happens, the disease is less likely to spread to people who aren't immune, because there just aren't enough infectious carriers.

"India has 1.38 billion people, a population density of about 400/sq km and a healthcare system ranked at 143 in the world. If we allow 60 per cent people to get infected quickly in the hopes of herd immunity, that would mean 830 million infections," Jameel said.

"If 15 per cent need hospitalization that means about 125 million isolation beds (we have 0.3 million). If five per cent need oxygen and ventilatory support, this amounts to about 42 million oxygen support and ICU beds; we have 0.1 million oxygen support beds and 34,000 ICU beds. This would overwhelm the healthcare system causing mayhem," he said.

Jameel said if the population level mortality is 0.5 per cent that would mean 40 lakh deaths. "Are we prepared to pay this price for herd immunity in the short term? Clearly not," he said.

He said it is unlikely that a vaccine would be available by the end of the year.

"Even then, we don't know yet how long it would give protection – weeks, months, one year, a few years? I don't think we will return to pre-coronavirus days for at least the next 3-5 years. This is also a chance to evaluate if we want to return to those unsustainable, environment-damaging ways. COVID-19 is a timely warning to reform our way of living," he said.

Jameel said it is hard to predict but plausible that COVID-19 would return in second or third wave.

"Later waves come when we don't understand the disease and become lax. A comparison to Spanish Flu is not entirely valid because in 1918 no one knew what caused it. No one had seen a virus till the mid-1930s as the electron microscope needed to view those was invented in 1931," he said.

"Today we know a lot more about the pathogen, its genetic makeup, how it transmits and how to prevent it. We need to be sensible and follow expert advice," he said.

If there is any scientific evidence linking deforestation, rapid urbanisation, climate change with pandemics like COVID-19, he said zoonotic viruses -- those that jump from animals to humans -- happen so when wild animal–human contacts increase.

"Deforestation destroys animal habitats bringing them closer to humans. When you cut forests, bats come to roost on trees closer to human habitations. Their viruses in secretions/stool get transmitted to domestic animals and on to humans. This happened clearly with Nipah virus outbreak in Malaysia in 1997-98 from fruit bats to pigs to humans," he said.

"COVID-19 possibly arose in wet animal markets due to dietary habits that bring all kinds of live and dead wild animals in close contact with humans," Jameel added.

Kolkata, Mar 25: Amid the countrywide lockdown in the wake of coronavirus outbreak, Chief Minister Mamata Banerjee on Wednesday said that all police stations will take responsibility to deliver food at doorsteps under the supervision of District Magistrates and Police Superintendents.
"As we have to ensure that there is no scarcity of food, all Police stations will take responsibility to deliver food at doorsteps and it will be monitored by District Magistrates and Police Superintendents," said Banerjee at a press conference here.
She also said that under the social pension schemes, the pension holders will get their pension of March and April together.
Speaking on local police blocking people involved in essential services, she said, "The Officer-in-charge will have to ensure that the local police know about the rules and exemptions during the lockdown."
"If any police official or an administrative official is found flouting the lockdown norms, then strict action will be taken against them," she added.
The Chief Minister also said, "If somebody needs to help us by giving materials then they need to contact health department official Sanjay Bansal, whose contact number is - 9051022000."
"The government has also launched a State emergency relief fund wherein people can donate. For donation, the account number is 628005501339, IFSC: ICIC0006280 and website: wb.gov.in," she said.
She also said that on March 31 the government will review the situation.
According to a recent update by the Ministry of Health and Family Welfare, a total of 562 positive cases for coronavirus have been confirmed in the country.
