Half-life of SARS-CoV-2 in saliva droplets:

Virus does not last long in high temperature, humidity & sunlight.

Bleach & isopropyl alcohol will kill the virus in 30-seconds to a few minutes on its own even w/o rubbing. Disinfectants are critical to limiting virus spread.

Indoor environments (climate controlled) have long survival time of virus on surfaces (6-18 hrs+) while outdoor environment w/sunlight: 1-3 minutes

= Florida beaches are considerably safer during middle-day, blazing sunshine than morning/evening.

ditto golf courses

Many speculating for months about weather effects on the coronavirus & now we have some hard data & evidence to guide responses:

Spring/Summer sunlight, warmth (70°F) & humidity outdoors kill the virus in minutes.

Disinfectant required in climate controlled indoors.
