Seeking loan waiver has become fashion these days: Venkaiah

Chennai, Apr 25: Civic authorities on Saturday turned down a plea for exhuming the body of a doctor who died of COVID-19 here and burying it in another cemetery, citing health experts' view that it was unsafe to do so. Citing a request from the wife of the deceased doctor to allow exhumation and then re-burial at a cemetery in Kilpauk, the Greater Chennai Corporation said it sought a report from a committee of public health experts to ascertain the feasibility of entertaining her plea.

The spouse of the doctor had appealed to the GCC on April 22 to exhume and bury again her husband's body. She had said that burial in the Kilpauk cemetery here was her husband's last wish and he had conveyed it to her before he was put on a ventilator.

The report of experts has said that "it is not safe" to exhume and again bury the body of a COVID-19 victim and hence "it is not possible to accept her request," the GCC said in an official release. On April 19, a city-based 55-year-old neurosurgeon died of coronavirus and his burial at the Velangadu crematorium here was marred by violence.

A mob which falsely feared that the burial may lead to the spread of contagion had attacked the corporation health employees and associates of the deceased doctor. The doctor's wife and son also had to leave the burial ground in view of the violence.

The body was brought to Velangadu as people of Kilpauk area had opposed his burial there. Over a dozen men involved allegedly in violence were arrested and remanded to judicial custody. Later, in a video message, the surgeon's wife had said that it was her husband's last wish to be interred at the Kilpauk cemetery as per Christian rituals

Chief Minister K Palaniswami and DMK president M K Stalin had spoken to her on Wednesday over the phone and condoled her husband's death.

Mar 2: Two more positive cases of the novel coronavirus -- one in Delhi and another in Telangana -were reported, the Union Health Ministry said on Monday.

The person from Delhi had travelled to Italy, it said adding he is being diagnosed at RML hospital.

The other person with the coronavirus infection has a travel history to Dubai, the ministry added.

"Both the patients are stable and being closely monitored," the ministry said.

Sunitha Krishnan is the name of the patient from Telangana and she is a social activist.

Krishnan has tweeted, "So going to enjoy hospitality at Gandhi Hospital for two days as admitted in the isolation ward suspected coronavirus. They have not started the tests yet( 1.30 hrs since I arrived).I believe the results make take 48hrs. At this pace, I have a feeling I am might be here sometime."

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.
