Thiruvananthapuram, Apr 10: Kerala Chief Minister Pinarayi Vijayan on Friday said that it has been 100 days since the first COVID-19 case was reported and shared the updated figures of positive cases, along with the efforts made by the state government to contain the virus.

"100 Days of #COVID19 | Kerala Story It's been 100 days since the first case was reported. 258 active cases, 97 recovered, Total confirmed: 357 Deaths: 2. 12,710 samples tested Special COVID-19 Hospital, 1,251 Community Kitchens, 28,08,650 Individuals Served, 3,676 Destitutes Rehabilitated," Vijayan tweeted.

India's first case was reported in Kerala in January. The patient was a student, who was studying at Wuhan University in China.

Meanwhile, the Ministry of Health and Family Welfare on Friday informed that India's total number of COVID-19 positive cases now stands at 6,412. Out of these, 5,709 are active patients and 504 of them have been cured/discharged and migrated.

With 30 new deaths reported in the last 12 hours, the death toll has reached 199.

Bengaluru, Jul 26: Paying tributes to the martyrs of Kargil war on its 21st anniversary, Karnataka Chief Minister B S Yediyurappa on Sunday said his government always stood by the soldiers and families of those who laid down their lives to protect the borders of the country.

"The government is always committed to the welfare of the soldiers. Karnataka has formed a separate department for the welfare of the soldiers and their families. We always stand with the families of the martyred soldiers," he said. He was addressing soldiers after paying tributes to the martyrs of the Kargil war at an official function organised on the occasion of Kargil Vijay Diwas at the National Military Memorial Park in the city by the Sainik Welfare and Resettlement Department under the state Home Department. 

Yediyurappa described as a symbol of India's valour and sacrifices the Kargil Vijay Diwas, observed to commemorate its victory over Pakistan in the war that ended on July 26, 1999 with recapture of the territory in Kargil. He said the state government has given due compensation to the families of the Kargil martyrs and the soldiers who were injured.

Recalling the conflict, Yediyurappa said Pakistan had set its eyes on grabbing the vast terrains of Kargil and Drass sector in Jammu and Kashmir but the Indian soldiers successfully fought a deadly battle at a height of 17,000 feet where the temperature goes up to minus 30 degrees celsius.

"The sacrifices of our soldiers will remain etched in our memories forever. The tale of the 527 soldiers, who sacrificed their lives to save our country, is a constant source of inspiration for our youth," the Chief Minister said. He also noted Karnataka's contributions to the Indian army and said the state had given two Generals, one Field Marshall, many army officers and innumerable soldiers to protect the country's borders. 

The current physical distancing guidelines provided by the World Health Organisation (WHO) and by the US Centers for Disease Control and Prevention (CDC) may not be adequate to curb the coronavirus spread, according to a research which says the gas cloud from a cough or sneeze may help virus particles travel up to 8 metres. The research, published in the Journal of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.

Study author, MIT associate professor Lydia Bourouiba, warned that droplets of all sizes can travel 23 to 27 feet, or 7-8 metres, carrying the pathogen.

According to Bourouiba, the current guidelines are based on "arbitrary" assumptions of droplet size, "overly simplified", and "may limit the effectiveness of the proposed interventions" against the deadly pandemic.

 She explained that the old guidelines assume droplets to be one of two categories, small or large, taking short-range semi-ballistic trajectories when a person exhales, coughs, or sneezes.

However based on more recent discoveries, the MIT scientist said, sneezes and coughs are made of a puff cloud that carries ambient air, transporting within it clusters of droplets of a wide range of sizes.

Bourouiba warned that this puff cloud, with ambient air entrapped in it, can offer the droplets moisture and warmth that can prevent it from evaporation in the outer environment.

"The locally moist and warm atmosphere within the turbulent gas cloud allows the contained droplets to evade evaporation for much longer than occurs with isolated droplets," she said.

"Under these conditions, the lifetime of a droplet could be considerably extended by a factor of up to 1000, from a fraction of a second to minutes," the researcher explained in the study.

The MIT scientist, who has researched the dynamics of coughs and sneezes for years, added that these droplets settle along the trajectory of a cough or sneeze contaminating surfaces, with their residues staying suspended in the air for hours.

"Even when maximum containment policies were enforced, the rapid international spread of COVID-19 suggests that using arbitrary droplet size cutoffs may not accurately reflect what actually occurs with respiratory emissions, possibly contributing to the ineffectiveness of some procedures used to limit the spread of respiratory disease," Bourouiba wrote in the study
