Bengaluru, Jul 7: Karnataka Chief Minister B S Yediyurappa on Tuesday held a meeting with a team of officials from the Union Health Ministry in Bengaluru in view of COVID-19 pandemic.

The team of Union Health Ministry officials praised the state's COVID-19 management measures.

Arti Ahuja, Additional Secretary, Ministry of Health, EMR director Ravindran met the Chief Minister during a two-day visit to the state. The team praised the State Government's efforts to gather information and identify co-morbid figures for the control of COVID-19.

During the meeting, it was discussed that in the following days, priority should be given to prevent death from COVID-19 and to provide adequate treatment for symptomatic infections.

In addition, Central team officials suggested that the COVID-19 guidelines should be followed in containment zones.

Officials informed about the steps being taken to treat COVID infected people in the state and stated that the High Flow Oxygen System is being implemented in all district hospitals and taluk hospitals in the state.  The process will be completed by August 15.

Health Minister B. Sriramulu, Medical Education Minister K. Sudhakar, Chief Secretary to Government Vijayabhaskar and other senior officials were present during the meeting.

Mangaluru, Jan 5: Against the backdrop of Mangalore violence of December 19, Additional Director General of Police of Karnataka Amar Kumar Pandey visited the city and held a meeting with senior police officers.

According to senior police officials here on Sunday, Dakshina Kannada and Udupi District Muslim Central Committee had planned to hold a protest against CAA at Nehru Maidan while the SKSSF had called for anti-CAA protest at State Bank area.

Though both the protests had been called off, there was an apprehension of a repeat incident of December 19 violence and hence the ADGP visited the city at the behest of state government and monitored the situation here for the entire day on Saturday.

The ADGP was unhappy that despite initial inputs and the imposition of Section 144 in the city, the situation on that day escalated to a level where police had to resort to firing only in this city.

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
