Extreme weather events on rise in India

New Delhi, Jan 9: The Union government has removed the central security cover of Tamil Nadu Deputy Chief Minister O Paneerselvam and DMK leader M K Stalin, officials said on Thursday.

They said while Paneerselvam had a smaller 'Y+' cover of central paramilitary commandos, Stalin had a larger 'Z+' protection.

The security cover of these two politicians has been taken off from the central security list after a threat assessment review was made by central security agencies and approved by the Union home ministry, they said.

Central Reserve Police Force (CRPF) commandos were protecting these two leaders of Tamil Nadu.

However, they said, the central security cover will be formally taken off after the state police takes over their security task, they added.

Jerusalem, Jul 23: Merging Israel's technological expertise with India's mass production capabilities, experts from the two countries have joined hands to develop rapid testing for Covid-19 in under 30 seconds.

Israel will soon send a high-level research delegation to India to conduct a series of "final stages of testing" as part of the joint effort to develop the rapid testing kits for Covid-19 .

A high ranking team from the Directorate of Defence Research and Development (DDR&D), in the Ministry of Defense, which has been working with India's DRDO to develop rapid testing for Covid-19 in under 30 seconds, is to leave from Tel Aviv to New Delhi on a special flight in a few days, Israel's Ministry of Defence said in a statement on Thursday.

Israel's Ministry of Foreign Affairs (MFA) and Ministry of Health are also involved in this unprecedented cooperation between the two countries which aims at "merging Israeli technology with Indian development and production capabilities to allow a swift resumption of normal life alongside the virus".

The DDR&D team will conduct a series of "final stages of testing" to determine the effectiveness of a number of rapid diagnostic solutions with their Indian counterparts.

Since the start of the pandemic, the DDR&D has tested dozens of diagnostic technologies. Some of them have matured and passed initial trials in Israel, however in order to complete testing and prove their effectiveness, these must be tested on a wide range of patients, IMoD said.

The four tech systems that will be tested are - voice test, breathalyzer test based on terra-hertz waves, isothermal test, and polyamino acids test.

"What they all have in common is the ability to detect the presence of the virus in the body quickly- usually within minutes. Developing diagnostic capabilities is a goal for the State of Israel and of many additional countries around the world. It is the most effective way to cut off 'chains of infection', prevent prolonged quarantine and enable the reopening of the global economy," the statement said.

"We hope that the research and development led by the DDR&D together with our excellent industries and academic institutions, will lead to a breakthrough that will change the way we diagnose and fight the virus, while giving the boost necessary to 'restart' our economy," Defense Minister Benny Gantz said.

Foreign Minister Gabi Ashkenazi noted that this cooperation provides a unique opportunity for scientific and technological cooperation that can assist Israel, India and the world in coping both with the pandemic and with the economic crisis that came with it.

The cooperation between Israel and India will enable the delegation and its Indian counterparts, to collect tens of thousands of samples in just ten days, and analyze them using computer systems based on artificial intelligence. This massive sampling will shorten processes and advance the approval of effective technology. All tests will be validated using PCR tests.

"The cooperation between India and Israel on Covid-19 is a good example of harnessing the scientific and technological strengths that the two countries have for larger, common good. It will also further deepen our strategic ties,” India's Ambassador Sanjeev Singla told PTI.

The flight will be carrying some breakthrough emerging Israeli technologies for combatting Covid-19, which have been donated by the Israeli foreign ministry and the private sector, in order to bolster India’s response to the virus outbreak.

The plane will also deliver mechanical ventilators which were given special permission by Israel for export to India.

Prime Minister Narendra Modi and his Israeli counterpart Benjamin Netanyahu have held three telephonic conversations since the outbreak of the pandemic and promised mutual assistance in dealing with the virus, committing to joint technological and scientific research between the countries.

The Israeli media widely reported that Modi lifted a ban on the export of Hydroxychloroquine at Netanyahu's request.

"The past few years have cemented the strategic relations between India and Israel and have included two historical visits of the Prime Ministers in Israel and in India," a press statement from the ministry of defence said.

"India seeks to integrate advanced technologies in its hospitals as they prepare to treat massive waves of Covid-19 patients on an Indian scale. The Israeli companies chosen by the MFA, MOD and Israel Defence Forces to be sent to India are potentially given unique access to one of the largest economies in the world to provide monitoring and treatment technologies while significantly reducing contact between the patients and the medical staff," it said.

"By opening the door to India’s market with its development and production capabilities, these Israeli technologies can be mass produced at a lower cost and could in future be jointly exported to third countries," it said.

"The COVID-19 pandemic is a global challenge, so it is only right that the solution be a global scientific cooperation between countries. India and Israel’s military R&D cooperation is well known for its success. I have no doubt the same will be seen in the private sector joined by brilliant scientific minds from both countries to introduce a breakthrough in swift and simple testing procedures,” said Prof. Nati Keller, an infectious diseases specialist from Sheba Medical Center, who is leading the medical side of the delegation.

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.
