Rahul targets SP, BJP over Muzaffarnagar riots

Hyderabad, Mar 31: Six people from Telangana who attended a religious congregation in Delhi's Nizamuddin died due to the novel coronavirus, the state government said on Monday.

"Coronavirus has spread among some of those who attended a religious prayer meeting from March 13 to 15 at Markaz in Nizamuddin area in Delhi," according to an official release. "Among those who attended were some persons from Telangana."

Two of the six died at the Gandhi Hospital, one each in two private hospitals, and one each in Nizamabad and Gadwal towns, the statement said, without mentioning the time of their deaths.

The special teams under the collectors have identified the persons who came in contact with the deceased and they are shifted to the hospitals, it said.

Police and paramilitary personnel cordoned off a major area in Nizamuddin West in south Delhi on Monday and over 200 people have been kept in isolation in hospitals after several people who took part in a religious congregation there showed symptoms of coronavirus.

The Telagana government asked those who participated in the prayers to inform the authorities. It will conduct tests and offer treatment to them free of cost, according to the release.

The government also requested the people to alert if they come to know about those who participated in the prayers.

Earlier a separate government release said a person died of COVID-19 in Telangana, taking the toll to two and the total number touched 77 after six fresh cases were reported on Monday.

As many as 13 patients who underwent treatment for the virus were discharged on Monday, a media bulletin on COVID-19 issued by the state government said.

A techie, the first COVID-19 case in Telangana, has been discharged recently. The state now has 61 active cases, the bulletin said.

Chief Minister K Chandrashekar Rao had on Sunday said barring a 76-year-old person, who had other ailments, the other patients were doing well.

Rao had said 25,937 people were under surveillance and being watched by 5,746 teams and they would be out of watch after completing their mandated 14-day quarantine period. He had said all those who are under observation would be out of vigil by April 7 if there are no fresh suspected cases.

"From March 30, their time is nearing completion. After that, they do not need to be under any surveillance. By April 7, we will have a situation of zero... We pray God that we should not get new cases,"

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.
