Detailed explanation-1: -Studies have so far shown that SARS-CoV-2 can survive in air droplets for as long as three hours and on some hard surfaces for up to three days.
Detailed explanation-2: -Recent findings have demonstrated that infectious SARS-CoV-2 can be recovered from non-porous surfaces for at least 28 days at ambient temperature and humidity (20 °C/68 °F and 50% relative humidity).
Detailed explanation-3: -Particles from an infected person can move throughout an entire room or indoor space. The particles can also linger in the air after a person has left the room – they can remain airborne for hours in some cases.
Detailed explanation-4: -Using the travel history and symptom onset of 88 confirmed cases that were detected outside Wuhan in the early outbreak phase, we estimate the mean incubation period to be 6.4 days (95% credible interval: 5.6-7.7), ranging from 2.1 to 11.1 days (2.5th to 97.5th percentile).
Detailed explanation-5: -The time from exposure to symptom onset (known as the incubation period) is thought to be two to 14 days. Symptoms typically appeared within five days for early variants, and within four days for the Delta variant. The incubation period appears to be even shorter – about three days – for the Omicron variant.
