Brahmins did not start untouchability: Pejawar seer

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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 26: The government of Karnataka has urged the Muslims to celebrate Eid al-Adha in a simple manner and follow all guidelines amid mounting cases of covid-19.

The festival, also known as Bakrid, will be celebrated on July 31 in coastal districts of Karnataka and on August 1 in other parts of Karnataka. 

In an order, A B Ibrahim, secretary of the department of minority welfare, Hajj and Waqf has prohibited offering Eid prayers in open grounds (Eidgahs) in the wake of pandemic.

Eid prayers can be offered in mosques by following all the necessary precautionary measures including maintaining physical distance. The congregation should not exceed 50 worshippers. If they number exceeds, they should be divided into three groups. 

However, except for mosques, no other places should be used for offering congregational prayer. 

Besides, all those who attend Eid prayers at mosque should compulsorily wear face masks. Entry is banned for people who are above the age of 60 years and below the age of 10. At least six feet distance needs to be maintained while offering prayer.

Thermal scanning needs to be done before entering the mosque. Hands need to be washed in soap or sanitizer. No one should touch the holy books in the mosque. Hand shaking and embracing to greet will also not be allowed. If any strangers are seen, their movement should be monitored.

Mangaluru, Jul 13: Air India Express flight brought around 170 passengers from Bahrain to Mangaluru under Vande Bharat Mission yesterday. 

This is the first VBM flight from Bahrain to Mangaluru. The flight took off from Bahrain at 10 am on Sunday and landed at Mangaluru International airport at 4.45 pm. 

Even though thousands of Indian expatriates from other gulf countries were brought to Mangaluru in past few weeks, no flight was arranged from Bahrain so far. Hence, several Mangalureans including senior citizens, women and patients were stranded in Bahrain for months together.

Local entrepreneur and president of Indian Overseas Congress (IOC) Mohammed Mansoor, who saw the plight of the hapless Indian expatriates in Bahrain had discussions with the Indian embassy in Bahrain and convinced it to arrange a special Air India Express flight under the Vande Bharat Mission. 

IOC, along with the cooperation of ‘KHK Heroes’ had arranged meal kits for passengers during their flight to Mangaluru. IOC had also contacted all the Mangaluru-based NRIs who wanted to fly back to India and made a list with the help of Indian embassy to avoid any untoward incidents.

IOC had also given details of hotels to be quarantined in Mangaluru and Udupi, names of nodal officers to be contacted and emergency telephone numbers. The passengers were given a warm farewell by the office bearers of IOC from Bahrain international airport.

The effort taken by Mohammed Mansoor, president of IOC is lauded by all. All the passengers who travelled by the flight have thanked IOC and its office bearers whole heartedly.
