JD(S)-BJP likely to forge alliance for zilla, taluk panchayats

Bengaluru, Jan 16: It was necessary to revise rates under the ECHS, CGHS and GIPSA schemes for private hospitals to be able to sustain, doctors from private hospitals have opined.

Under the banner of the Association of Healthcare Providers of India (AHPI), doctors from top private hospitals in the city spoke about the dues pending from the union government schemes. They said they could not give a deadline as to when they would stop offering the scheme.

In a press release issued here on Thursday association said, which had previously told the government that they would not treat patients under the scheme owing to dues, mellowed down after the government released Rs 250 crore out of the Rs 1,000 crore dues.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Jun 24:  Karnataka on Wednesday reported 397 new coronavirus positive cases, taking the total number of positive cases to 10,118.

According to the State Health Department, with 14 more deaths today, the state's toll has reached 164. While, 6,151 people have been discharged so far.

Hundred per cent of Community Health Centres, 50 per cent of Primary Health Centres and Urban Primary Health Centres will be converted as exclusive 'fever clinics' to screen fever cases for influenza-like illness (ILI)/severe acute respiratory infections (SARI), Karnataka Health Department said.
