Indians stuck in Saudi Arabia due to lockdown ought to know these things before returning home

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Jan 24: After Honnalli legislator MP Renukacharya, Ballari City MLA Somashekara Reddy and deputy chief minister Govind Karjol, it appeared the turn of revenue minister R Ashoka to show the BJP in poor light with controversial and provocative comments against a minority community. This, despite a gag order issued by state BJP president Nalin Kumar Kateel.

Responding to questions on the Mangaluru International Airport bomb scare incident and how the main accused would have been treated had he been a Muslim, Ashoka on Thursday said "all anti-nationals must be shot dead". Meanwhile, Renukacharya, also a political secretary to chief minister BS Yediyurappa, continued his tirade against Muslims, insisting the government will not extend any "special package" to the community.

Soon after garlanding the statue of Netaji Subhas Chandra Bose on the birth anniversary of the freedom fighter, at Vidhana Soudha on Thursday, Ashoka said: "All those who are singing the tune of Pakistan and indulging in anti-national activities, be they Hindu, Christian or Muslim, must be shot dead."

Asked to respond to former chief minister HD Kumaraswamy’s accusation that the entire Mangaluru bomb incident was stage-managed by the BJP government to divert attention, Ashoka said the JD(S) functionary "must measure his words" and not speak "like a film director who can project the police as villainous all the time".

"Kumaraswamy is a former CM. When in power, police were his closest friends, but now that he is not in government, the same police are villains," Ashoka said.

The minister reiterated the government’s stand — first floated by home minister Basavaraj Bommai —

that Aditya Rao, the main accused in the Mangaluru bomb incident, is "mentally unstable" and needs to be medically examined.

Renukacharya, meanwhile, justified comments made on Wednesday that the government will not offer Muslims "a special package".

"When they [Muslims] need development funds, they come to us and seek special packages. Once they get funds, they then vote for Congress or JD(S) in elections," Renukacharya said on Thursday. "We do not need people with such double standards. I will apply pressure on all ministers in the cabinet and even the chief minister to ensure they do not allocate any special package for the community."

May 1: India on Thursday called as "propaganda" certain social media posts from the Arab world alleging harassment of Muslims in several parts of the country in the name of containing the spread of coronavirus.

Strongly rebutting the charges, External Affairs Ministry Spokesperson Anurag Srivastava said the Gulf countries are deeply committed to friendly relations with India and they are even seeking bilateral talks on the post-COVID-19 economic recovery.

Talking about India's close and traditional ties with the Arab countries, he said New Delhi is ensuring uninterrupted supply of food and essential commodities to the region during Ramzan as part of its deep-rooted friendship.

Srivastava said the countries in the region do not support any interference in India's internal affairs.

"Much of what you see is propaganda by interested parties. Stray tweets can not be used to characterise our bilateral ties with these countries. The real picture of these relations is very much different," he said during an online media briefing.

There has been a wave of angry reactions on Twitter by leading citizens and rights activists from various Arab countries following allegations that Muslims are being blamed for spreading COVID-19 in several parts of India.

The Organisation of Islamic Cooperation, a powerful bloc of 57 countries, recently accused India of "Islamophobia". India rejected the charges as regrettable.

"We have been making special efforts to ensure uninterrupted supply of food and essential commodities which are required during the Ramzan period in these countries, and this is something which has been greatly appreciated. These countries also want a priority discussion with India on the post-COVID-19 economic recovery," Srivastava said.

Prime Minister Narendra Modi and External Affairs Minister S Jaishankar have been in regular touch with their counterparts from the region in the wake of the coronavirus pandemic.

"In these discussions, there have been requests for sending medicines and medical teams to these countries. We already deployed a Rapid Response Team in Kuwait. There is also a request to send doctors and nurses from India," said Srivastava.

"What comes out clearly is that these countries are deeply committed to friendly relations with India. They also do not support any interference in internal matters of India. It is, therefore, important that the friendly and cooperative nature of our relations is accurately recognised and the misuse of social media is not given credence," he added.

Asked about reports of an order issued by Oman's Finance Ministry asking all state-owned companies to replace foreign workers with qualified local Omanis, Srivastava said it is not aimed at Indians working in the Gulf nation.

"The policy is a decades-old one and not specific to India. It does not target the Indians in any way," he said.

There have been apprehensions that the order will render thousands of Indians working in state-run firms in Oman jobless.

"They greatly value relationship with India. Government of Oman is taking special care of Indians which included free testing for coronavirus, its treatment, providing food," the MEA spokesperson said.

Oman government is also extending certain categories of visas of Indians.

Srivastava said India has been in touch with its friends and partners across the world as part of the collaborative approach to dealing with the pandemic.
