19 coronavirus patients in Kerala cured, active cases stand at 178 in State

Thiruvananthapuram, Apr 5: Eight more COVID-19 positive cases were reported from Kerala on Sunday, four among whom attended the Tablighi Jamat congregation in Delhi and six people were cured, Health Minister K K Shailaja said.

With this, the total number of affected people under treatment in the state has gone up to 256, she said.

"Out of the eight cases, five are from Kozhikode, and one each from Pathanamthitta, Kannur and Kasaragod districts.

In the case of Kozhikode, four out of the five returned from Nizammuddin meet and one from Dubai.

As of date, 10 people who had returned from Nizammuddin in Delhi have been tested positive," the minister said in a release

A total of 314 cases have been reported from Kerala so far and 56 people have been cured, she said

"We have sent 10,221 samples for testing," she said.

A total of 1.58 lakh people are under observation in the state, out of which 776 are in isolation wards in hospitals.

Bengaluru, Feb 3: India's manufacturing activity expanded at its quickest pace in nearly eight years in January with robust growth in new orders and output, a private survey showed on Monday, suggesting the economy may be getting back on firmer footing.

In response to the jump in sales, factories hired new workers at the fastest rate in more than seven years.

If sustained, the improvement in business conditions could point to a gradual economic recovery in coming months, as forecast by analysts in a Reuters poll last month, after growth slowed to a more than six-year low in the July-September quarter.

The Nikkei Manufacturing Purchasing Managers' Index , compiled by IHS Markit, jumped to 55.3 last month from 52.7 in December. It was the highest reading since February 2012 and above the 50-mark separating growth from contraction for the 30th straight month.

"The PMI results show that a notable rebound in demand boosted growth of sales, input buying, production and employment as firms focused on rebuilding their inventories and expanding their capacities in anticipation of further increases in new business," Pollyanna De Lima, principal economist at IHS Markit, said in a news release.

A new orders sub-index that tracks overall demand hit its highest level since December 2014 and output grew at its fastest pace in over seven and a half years, pushing manufacturers to hire at the strongest rate since August 2012.

Meanwhile, both input costs and output prices rose at a slower pace, indicating overall inflation may have eased after hitting a more than five year high of 7.35% in December, although probably not below the Reserve Bank of India's medium-term target of 4%.

That might keep the central bank, which cut its key interest rate by a cumulative 135 basis points last year, on the sidelines over the coming months.

"To complete the good news, there was also an uptick in business confidence as survey participants expect buoyant demand, new client wins, advertising and product diversification to boost output in the year ahead," added De Lima.

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.
