Bengaluru, Apr 15: Karnataka and five other states have their coronavirus antibody test kits stuck in China because of the country's new policy of getting clearance from their government before a company exports its products.

Singapore-based Sensing Self Ltd and China’s Wondfo are the only companies that have cleared Pune's National Institute of Virology (NIV)’s validation for rapid antibody test kit.

Dr CN Manjunath, Director, Jayadeva Institute of Cardiovascular Sciences and Research, and nodal officer for COVID-19 lab testing, Karnataka, said, "Inventory is ready in Hong Kong Airport. Karnataka's consignment is stuck with five other states' consignments: Kerala, Andhra Pradesh, Rajasthan, Gujarat, and Meghalaya. On April 1 or 3, China's policy changed saying any exports going out of China has to be certified by the Chinese government."

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, May 21: With temples yet to open for devotees as coronavirus restrictions are in place, the Karnataka government is preparing for live streaming of sevas (service) and poojas offered to deities at temples that comes under the state's Hindu Religious Institutions and Charitable Endowment Department.

The government has also decided to develop an app and web-based software with an intention to provide information to devotees regarding temples, also to facilitate online donations and advance booking for various sevas offered there.

Regarding online live streaming, Commissioner of the Hindu Religious Institutions and Charitable Endowment Department has written to the Deputy Commissioners of all the districts and Executive Officers seeking a list of temples that comes under their jurisdiction where such facility can be provided.

"It has been intended to do online live streaming of sevas and pooja rituals at temples that come under the department in the backdrop of COVID-19 crisis. In this regard it is requested to provide a list of temples where online live facility can be provided to devotees, by abiding the traditions and practices of the temple," the letter said.

Though the temples are holding daily poojas and rituals, they are not open to public for now, with COVID-19 induced lockdown restrictions in place.

Officials had recently had stated that the department was planning to have a standard operating procedure (SOP) in place, that needs to be followed at temples in a post lockdown scenario, once they are opened for the public.

There are over 34,000 temples in the state that come under the department.

Meanwhile, in another letter to DCs of 15 districts, also Executive officers and administrators of 'A' grade temples, aimed at development of app and web-based software, the Commissioner has sought information regarding sevas offered at temples in their jurisdictions and those sevas for which option can be provided for devotees to do advance booking.
