Corona scare hits Kerala police as 70 cops including SP, go on quarantine after 3 test positive

New Delhi, Apr 29: India's tally of COVID-19 cases has reached 31,332, said the Union Ministry of Health and Family Welfare on Wednesday. With 73 more deaths reported, the number of deaths due to coronavirus in the country breached the 1,000 mark and stood at 1,007.

The tally is inclusive of 22,629 active coronavirus cases, 7,695 patients who have been cured/discharged and one patient migrated.

According to the Ministry, Maharashtra has the most number of COVID-19 cases with 9,318 cases of which, 1,388 patients have been cured/discharged while 400 patients have succumbed to the virus.

Gujarat has the second-highest number of positive cases in the country with 3744 cases including 434 patients cured/discharged and 181 deaths.

Delhi's tally stands at 3314 cases of which, 1078 patients have recovered while 54 patients have succumbed to the virus.

Madhya Pradesh has a total of 2387 positive cases including 377 patients recovered/discharged and 120 fatalities.

Meanwhile, Goa (seven cases; all seven recovered), Arunachal Pradesh (one case; now recovered), Manipur (two cases; both recovered), Tripura (two cases; both recovered) have reported no new cases of COVID-19.

Kolkata, Jun 19: The nationwide clamour for boycott of Chinese goods is getting louder amid the Ladakh face-off, with traders urging the Centre to direct e-commerce firms to restrict the sale of items from the Dragonland, which imports products worth USD 74 billion to India annually.

Of the total import from China, retail traders sell goods worth around USD 17 billion, mostly comprising toys, household items, mobiles, electric and electronic goods and cosmetics among other things, which could possibly be replaced by Indian products, a national trading body said.

"We, at 'Federation of All India Vyapar Mandal', are advising our members to clear their stocks of Chinese products and refrain from placing fresh orders. We are also requesting the government to restrict e-commerce companies from selling Chinese products," V K Bansal, the association's general secretary, told PTI.

Sushil Poddar, the president of the Confederation of West Bengal Traders Association, said its members have been told to shun trading in Chinese goods as much as possible.

Another national traders' body, The Confederation of All India Traders (CAIT), has decided to step up its movement against the boycott of Chinese goods, under its campaign 'Bhartiya Samaan-Hamara Abhimaan'.

It released a list of over 450 broad categories of commodities, comprising 3,000 Chinese products.

Washington, Apr 23: Air pollution over northern India has plummeted to a 20-year-low for this time of the year, according to satellite data published by US space agency National Aeronautics and Space Administration (NASA).
The US space agency's satellite sensors observed aerosol levels at a 20-year low post the countrywide lockdown, implemented to slow the spread of the novel coronavirus.

"We knew we would see changes in atmospheric composition in many places during the lockdown," said Pawan Gupta, a Universities Space Research Association (USRA) scientist at NASA''s Marshall Space Flight Center. "But I have never seen aerosol values so low in the Indo-Gangetic Plain at this time of year," added Mr Gupta.

Acting Assistant Secretary of State for South and Central Asia Alice G Wells tweeted, "These images from NASA were taken each spring starting in 2016 and show a 20-year low in airborne particle levels over India. When India and the world are ready to work and travel again, let's not forget that collaborative action can result in cleaner air."

The data published with maps show aerosol optical depth (AOD) in 2020 compared to the average for 2016-2019. Aerosol optical depth is a measure of how light is absorbed or reflected by airborne particles as it travels through the atmosphere.

If aerosols are concentrated near the surface, an optical depth of 1 or above indicates very hazy conditions. An optical depth, or thickness, of less than 0.1 over the entire atmospheric vertical column is considered "clean." The data were retrieved by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite.

In the first few days of the lockdown, it was difficult to observe a change in the pollution signature. "We saw an aerosol decrease in the first week of the shutdown, but that was due to a combination of rain and the lockdown," said Mr Gupta.

Around March 27, heavy rain poured over vast areas of northern India and helped clear the air of aerosols. Aerosol concentrations usually increase again after such heavy precipitation.

"After the rainfall, I was really impressed that aerosol levels did not go up and return to normal. We saw a gradual decrease and things have been staying at the level we might expect without anthropogenic emissions," Mr Gupta said.

On March 25, the Indian government placed its 1.3 billion citizens under a strict lockdown to reduce the spread of COVID-19. The countrywide mandate decreased activity at factories and severely reduced car, bus, truck and airplane traffic. Every year, aerosols from anthropogenic (human-made) sources contribute to unhealthy levels of air pollution in many Indian cities.

Aerosols are tiny solid and liquid particles suspended in the air that reduce visibility and can damage the human lungs and heart.

In southern India though, the story is a little hazier. Satellite data show aerosol levels have not yet decreased to the same extent. In fact, levels seem to be slightly higher than in the past four years. The reasons are unclear but could be related to recent weather patterns, agricultural fires, winds or other factors.

"This a model scientific experiment," Robert Levy, program leader for NASA's MODIS aerosol products, said about the lockdown and its effects on pollution.

"We have a unique opportunity to learn how the atmosphere reacts to sharp and sudden reductions in emissions from certain sectors. This can help us separate how natural and human sources of aerosols affect the atmosphere," Mr Levy added.
