Paper leak: CBSE orders re-exam of Class X Maths, Class XII Economics

New Delhi, Apr 26: The total count of coronavirus cases in the country surged to 26,917 on Sunday.

The total COVID-19 cases in the country are inclusive of 5,913 cured and discharged patients, one migrated, and 826 deaths. At present, there are 20,177 active COVID-19 cases in the country.

The Federation of Resident Doctors' Association (FORDA) wrote to the Union Health Minister, Dr Harsh Vardhan, seeking assistance regarding accommodation facilities for resident doctors advised for home quarantine.

In a letter to the Health Minister, the association stated that recently there have been reports of resident doctors from various hospitals who tested positive for COVID-19. As a consequence, their primary contacts who are mostly their colleagues and resident doctors, have been advised to be on home quarantine, the association added.

On the other hand, Maharashtra continues to have the largest number of COVID-19 positive cases at 7,628 . 1,076 persons have been cured in the state while 323 persons have died.

Fresh cases have been reported several states including West Bengal, Maharashtra, Rajasthan and Uttar Pradesh.

The total number of cases in Indore has risen to 1,176, including 57 deaths.

While 133 deaths have been reported from Gujarat where the total number of cases spiked up to 3,071.

Kerala has seen a recovery rate of around 74 per cent as 338 out of the total 457 COVID-19 positive patients recovered in the state with only 4 fatalities.

Delhi has seen 2,625 COVID-19 positive cases and 54 deaths due to the pandemic.

Here's a quick read on the COVID-19 related updates:

10. Indian High Commission here on Sunday said two Air India and one Blue Dart flights will send about 78 tonnes of cargo to India as part of the 1 million PPE kits being sourced from Singapore-based company.

New Delhi, Mar 25: The total number of confirmed coronavirus cases in India rose to 562, according to the Ministry of Health and Family Welfare on Wednesday.
This includes 512 active cases, while 40 infected people have already been cured or discharged.
The Union Health Ministry said that total deaths due to the disease now stand at 9, as the second death reported in Delhi is COVID-19 negative. One patient has also migrated due to the infection.
The Central government has taken several steps to contain the rapid spread of the virus including the screening 15,24,266 passengers at the airports.
Prime Minister Narendra Modi had on Tuesday announced a 21-day lockdown in the entire country effective from midnight to deal with the spread of coronavirus, saying that "social distancing" is the only option to deal with the disease, which spreads rapidly.
In a televised address to the nation, Prime Minister Modi said that it is vital to break the chain of the disease and experts have said that at least 21 days are needed for it.
The Prime Minister, who had also addressed the nation last week, said the lockdown has drawn a "Lakshman Rekha" in every home and people should stay indoors for their own protection and for that of their families. 

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.
