Mangaluru, May 5: A day after lockdown was partially relaxed in Dakshina Kannada, a fresh covid-19 positive case was reported today from Boloor area of Mangaluru.

In its fresh bulletin, health and family welfare department today said that the throat swabs of a 51-year-old man from Boloor tested positive for the coronavirus.

Boloor is already declared as corona containment zone in the district after as this is the fourth coronavirus positive case reported from the area.

With this, the total number of coronavirus cases in Dakshina Kannada mounted to 25 including 19 residents of the district and six outsiders who have already left the district after getting treatment.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Mangaluru, June 22: A chartered flight from Dammam with more than 170 stranded Saudi Kannadiga passengers landed at Mangaluru International Airport at 8.53 pm. 

The flight was chartered by Saudi Kannadigas Humanity Forum (SKHF), an unregistered NGO, which was formed recently to help the Kannadigas stranded in Saudi Arabia due to covid-19 lockdown under the leadership of Zakariya Jokatte, president of Jubail unit of Bearys Chamber of Commerce and Industry and KS Sheikh Karnire, Director of Expertise Contracting Co. Ltd, Saudi Arabia.

There were 165 adults and 8 infants on board the IndiGo flight. All the passengers were screened at the airport. They will be dispatched to quarantine centres after completing formalities. 

SKHF had launched an online portal to assist those who were in need of emergency repatriation such as elderly people, those who lost their jobs, pregnant women and those who are in need of emergency medical treatment back home in India. 

SKHF coordinated with the authorities concerned to carry out all the formalities and legal procedures in Saudi Arabia. SKHF members were present at the Dammam Airport to help the passengers during the departure. 

Mr Jokatte and Mr Sheikh have thanked U T Khader, Mangaluru MLA and Dr Arathi Krishna, former deputy chairperson of NRI forum of government of Karnataka, for their help in chartering the flight.
