New Delhi, Apr 24: The death toll due to the novel coronavirus rose to 723 with 37 fatalities reported since Thursday evening, while the number of cases saw a record jump of 1,752 to go up to 23,452 cases on Friday, according to the Union health ministry.

The previous highest single day increase was on April 20 when 1,540 cases were reported.

The number of active COVID-19 cases stood at 17,915 as 4,813 people were cured and discharged, and one patient migrated, the ministry said.

Thus, about 20.52 per cent of the cases have recovered so far, an official of the ministry said. 

The Indian Council of Medical Research (ICMR) said that 23,502 samples have been confirmed positive as on April 24 at 9 am.

The health ministry's figure of 23,452 cases include 77 foreign nationals.

A total of 37 deaths were reported since Thursday evening of which 14 fatalities were reported from Maharashtra, nine from Gujarat, three from Uttar Pradesh, two each from Andhra Pradesh, Delhi, Madhya Pradesh, Tamil Nadu and Telangana and one from Karnataka, the ministry's data stated.

Of the 723 deaths, Maharashtra tops the tally with 283 fatalities, followed by Gujarat at 112, Madhya Pradesh at 83, Delhi at 50, Andhra Pradesh at 29, Rajasthan at 27 and Telengana at 26.

The death toll reached 24 in Uttar Pradesh, 20 in Tamil Nadu while Karantaka has reported 18 deaths.

Punjab has registered 16 deaths while West Bengal has reported 15 fatalities.

The disease has claimed five lives in Jammu and Kashmir, while Kerala, Jharkhand and Haryana have recorded three COVID-19 deaths each.

Bihar has reported two deaths, while Meghalaya, Himachal Pradesh, Odisha and Assam have reported one fatality each, according to the ministry data.

However, a news agency tally of the figures reported by various states as on Friday showed 23,577 cases and 743 deaths in the country.

There has been a lag in the Union health ministry figures, compared to the number of deaths announced by different states, which officials attribute to procedural delays in assigning the cases to individual states.

According to the ministry's data updated in the evening, the highest number of confirmed cases in the country are from Maharashtra at 6,430 followed by Gujarat at 2,624, Delhi at 2,376, Rajasthan at 1,964, Madhya Pradesh at 1,852 and Tamil Nadu at 1,683.

The number of COVID-19 cases has gone up to 1,604 in Uttar Pradesh, 984  in Telangana and 955 in Andhra Pradesh. The number of cases has risen to 514 in West Bengal, 448 in Kerala, 463 in Karnataka, 427 in Jammu and Kashmir,  277 in Punjab and 272 in Haryana.

Bihar has reported 176 coronavirus cases, while Odisha has 90 cases. Fifty-five people have been infected with the virus in Jharkhand and 47 in Uttarakhand. Himachal Pradesh has 40 cases, Chhattisgarh and Assam have registered 36 infections each so far.

Chandigarh has 27 COVID-19 cases, Andaman and Nicobar Islands 22 while  18 cases have been reported from Ladakh.

Meghalaya has reported 12 cases, and Goa and Puducherry have seven COVID-19 cases each.

Manipur and Tripura have two cases each, while Mizoram and Arunachal Pradesh have reported a case each.

"Our figures are being reconciled with the ICMR," the ministry said on its website.

States wise distribution is subject to further verification and reconciliation, it said.

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.

New Delhi, Apr 6: With an increase of 490 cases in the last 12 hours, the total number of COVID-19 positive cases in India climbed to 4067, said Ministry of Health and Family Welfare on Monday.

As many as 109 deaths have been reported across the country due to the deadly disease.
There are 3666 active cases in the country while 292 people have been cured/discharged/migrated.

Maharashtra has reported the highest number of COVID-19 cases so far, standing at 690, followed by Tamil Nadu and Delhi with 571 and 503 cases respectively.
