Contagious coronavirus

The contagiousness of the coronavirus (COVID-19) is not yet fully understood. It is known to spread through the air, particularly in closed environments like buses and rooms.

A one-time, brief encounter seems unlikely to transmit the disease, but a prolonged, repeated encounters with an infected person seems to have a high likelihood of contracting the disease.

A study of contagion in China showed that a single infected passenger riding on a bus caused numerous other passengers to be infected by the same virus. Coronavirus is thought to be more contagious than the ordinary flu.

At a nursing home in the State of Washington where at least 25 of the residents (patients) have died from COVID-19, more than half of the residents have also tested positive for the virus despite a lack of likelihood of direct contact with other residents. In addition, there have been widespread infection about the employees:

Of the 180-plus workers at the Life Care Center in Kirkland, 47 have tested positive and 24 have tested negative for COVID-19, KIRO-TV reporter Alison Grande tweeted. One employee had an inconclusive test and five are still waiting for their results. Another 18 were scheduled for testing Saturday and 95 are symptomatic, according to Grande’s tweet. It wasn’t clear if the 95 who have symptoms have been tested.
