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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Jul 10: Accredited Social Health Activist (ASHA) workers under the All India Trade Union Congress (AITUC) on Friday held protests in different parts of Karnataka, demanding personal protective equipment (PPE) kits and a salary of at least Rs 12,000 per month.

According to Madhu Kumari, an ASHA worker from Kalaburgi, ASHA workers currently receive a salary of Rs 3,000 per month.

"Our demand is to increase our wages to at least Rs 12,000 per month. We have been making this demand for the last six months but we have not received any response from the authorities. We will not go back to work until we are given an appropriate response. We did not want to create a difficult situation but the government has given us no choice," Kumari told ANI.

Clad in their signature pink saris, the women were holding posters in their hands and raising slogans to demand appropriate salary for their work and the necessary equipment to protect themselves from the ongoing COVID-19 pandemic.

Farhana, an ASHA worker protesting in Shivamogga, said that the women have been making demands for PPE kits since June 30. "We have been taking care of COVID patients for the last few weeks but have not received adequate PPE kits. A few of us received some in the beginning but they were not enough. We are not even given hand sanitiser or masks to protect ourselves," she added.

"We have sent letters to the District Commissioner's Office and to the Ministry of Health and Family Welfare but our pleas have gone unheard. We are protesting to get the attention of the concerned authorities," she added.

They also demanded that authorities to conduct their COVID-19 tests as they have to deal with patients infected with the virus.

Sajida, an ASHA worker in Kalaburagi said, "We are very stressed about the COVID situation. We take care of sick people day in and day out, but no one is there to take care of us. We want the government to conduct COVID tests for all ASHA workers in the state."

Bengaluru, Jul 11: Amidst the mounting number of covid-19 cases, Karnataka is witnessing another disturbing trend of increasing number of people ending their life. After the lockdown was relaxed, the state saw a worrying jump in the number of suicides.

According to statistics, as many as 2,211 suicide cases have been registered in just two months. The number of suicides rose by 23% in May to 1,127, and by another 18% in June to 1,084, from an average of 912 suicides in the first three months of the year. 

In April, however, the number nearly halved to 477. But April was also the month during which the lockdown (announced on March 24) was complete, and everyone was at home -- which, experts say, could have prevented people with suicidal tendencies from taking their own lives.

Shockingly, number of teenagers including school children committing suicide also increased in the state in past couple of months.

With the pandemic still accelerating and impacting people in multiple ways, the World Health Organisation has urged people to pay greater attention to mental health and suicide prevention. 

Dr Poonam Khetrapal Singh, Regional Director, World Health Organisation (WHO), South-East Asia Region, said stigma related to Covid-19 infection may lead to feelings of isolation and depression. Another precipitating factor impacting mental health amidst Covid-19 could be domestic violence, which is reported to have increased globally as several countries imposed lockdowns, she said.

“Hitting lives and livelihoods, the pandemic is causing fear, anxiety, depression and stress among people. Social distancing, isolation and coping with perpetually evolving and changing information about the virus has both triggered and aggravated existing and pre-existing mental health conditions, which need urgent attention,” she said.

Dr H Chandrashekar, professor and head of the department of psychiatry at Victoria Hospital, said reasons for suicide are always multi-factored, combined, cumulative, unresolving and interrelated.

“There is grief everywhere now due to deaths related to Covid-19, and it may have an adverse effect on some. But people should be watchful of their family members, especially those who are in depression and have a history of suicide attempts. One should never ignore signs, like when someone says they feel like ending their life. They should not be left alone, and unconditional support needs to be given. Also, objects that could be used to commit suicide must be kept away from them,” Dr Chandrashekar said.
