Pre-poll gift: Karnataka staff set for 24-30% hike, one more day off

Kasaragod, Apr 29: Kasaragod's General Hospital on Tuesday discharged the last of its 89 COVID-19 patients, who were admitted since the outbreak of the disease last month.

The patient discharged on Tuesday is a native of Anankur in Kerala. He was under treatment for 27 days following his return from Dubai. He was given a warm send-off at 12 noon by the doctors and hospital staff.

Of the 175 positive cases in Kasaragod district, only 12 are under treatment in other hospitals in the district now. Of them, seven had come from the Gulf and the remaining five were those in contact with them.

During a press meet, Chief Minister Pinarayi Vijayan, while referring the Kasaragod General Hospital's success story, congratulated the doctors, nurses and medical staff for the achievement.

According to Health Department, in spite of treating the highest number of COVID-19 patients in the state with meagre infrastructural facilities and even without the support of a medical college in the district, there have been no deaths.

According to the district administration, Kasaragod has conducted 4,112 tests so far, out of which 3,104 tested negative and the results of 833 are awaited.

The team of doctors, nurses and other staff numbering 250 is led by Dr Rajaram K Kandiyil, Superintendent of the Kasaragod General Hospital.

Bengaluru, May 7: Karnataka Minister for Labour Shivaram Hebbar, on Thursday, ordered issuance of notice to employers who have not paid salary to the workers during lockdown period amid Coronavirus threat in the state.

The Ministry has also directed serving notice to those employers who have reduced the wages of the workers in April '20, official sources told UNI here.

State Chief Minister B S Yediyurappa had appealed to the employers not to retrench any employee from the job because of their failure to attend to work because of Coronavirus which is spreading like wildfire and since they have been asked to remain in the house.

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
