Cong candidate to file complaint with CEC against PM Modi for lies and false promises

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Bengaluru, Apr 26: Two businessmen brothers, Tajammul Pasha and Muzammil Pasha, in Karnataka's Kolar district have set out to help people in need amid the lockdown over the COVID-19 pandemic by selling their land for Rs 25 lakh.

On seeing daily wage labourers and their families in Kolar suffer during the lockdown, the brothers said they decided to sell their land and use the money to buy essentials and food grain for a large number of poor people.

The brothers also bought oil and cereals with the money. Then they set up a tent next to their house and started a community kitchen to make food for labourers and homeless people.

"Our parents died early. When we shifted to our maternal grandmother's place at  Kolar, people from communities, Hindus, Sikhs, Muslims helped us survive without any religious bias," said Tajammul Pasha, visibly emotional.

The Pasha brothers are into banana cultivation and real estate. Tajammul was five and his sibling Muzammil was three when they lost their parents. They had to move from Chickbalapor to Kollar, where their grandmother lived.

"We were brought up in poverty. We survived because of the support of people of all communities and religions. We have signed the society agreement bond and handed it over to our friend who purchased our site and gave the money," the brothers said.

Once the lockdown ends and the land registrar's office opens, the remaining steps to transfer the land will be completed, they said.

So far the two brothers have supplied food grain, oil, sugar and other essentials to over 3,000 families. They have also given hand sanitizers and masks to the poor.

The Kolar administration has issued passes to their volunteers so that they can help in this difficult time.

The number of coronavirus cases in India has increased to 24,506, including 775 deaths, the Home Ministry said today, adding that 1,429 cases and 57 deaths were reported in the last 24 hours.

Amid a countrywide lockdown to check the spread of the highly contagious illness, which began on March 25, the government last night issued an order to allow neighbourhood shops to remain open with conditions; malls across India continue to remain shut.

Tumkur, Jan 10: A five-year-old boy has been killed by a leopard in Gubi taluk of Tumkuru district in Karnataka.

The local police said today that the incident took place on Thursday evening when the boy was returning home along with his grandmother.

The leopard first attacked a cow and then the boy who was behind it. The feline dragged the body into the forest.

After a search operation by the forest officials, the body was found and handed over to the parents after post-mortem.
