Mangaluru, June 1: The private bus services resumed services in Dakshina Kannada and Udupi districts today with 15 per cent hike in the fares. For 70 days these buses were stayed off the roads as lockdown was imposed in the region on March 22 in the wake of covid-19 outbreak.

Buses were sanitised in the morning. The bus operators have decided to operate only a few of the buses initially.

Of the about 2,000 service buses (inter-district buses and long-route buses within the district) of private operators in Dakshina Kannada and Udupi, only 25% resumed services. Only 135 out of 320 city buses in Mangaluru resumed services.

The number of passengers on board the buses were also very less in the morning. A few buses had arranged sanitisers for passengers, drivers and conductors.

Mangaluru, Apr 18: Mangaluru Police have registered a case against two foreign nationals, who were under home quarantine in Kodailbail, for allegedly spitting in the lift of their apartment building on Friday.

The two men, along with three of their roommates, have now been sent to a quarantine facility.

The residents of the residential complex have mentioned in their complaint that they have the CCTV footage of the two spitting in the lift.
Further investigation in the case is underway.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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