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. The virus can also survive on surfaces, such as cardboard (up to 24 hours), or plastic and stainless steel (up to 3 days). Estimates are that this virus survives on glass for up to 4 days.
The most common means of transmission of this disease is touching a recently infected surface, and then touching one's own face. As with any virus, its strength diminishes over time on virtually any surface.
Though underreported, hot temperatures kill COVID-19:
|“|| Only minimal reduction in virus concentration after 21 days at 4°C and -80°C.
Reduction in virus concentration by one log only at stable room temperature for 2 days. This would indicate that the virus is more stable than the known human coronaviruses under these conditions.
A study of a bus-rider in China
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.
Four players on the Nets
Four (4) basketball players on the same team (Nets) -- one of whom is injured and thus does not play/practice with the others -- have coronavirus.
This is known only because the team paid for private testing, which the FDA and CDC belatedly allowed (private testing was prohibited by these totalitarian agencies earlier).
Only 1 of the 4 is symptomatic, which can mean many asymptomatic people are carrying and spreading the virus.
Washington nursing home
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.
Occasional, brief encounters
A one-time, brief encounter seems unlikely to transmit the disease, as many politicians who met with someone who had the coronavirus have not themselves contracted the disease. But a prolonged, repeated encounter with an infected person seems to have a high likelihood of contracting the disease.
