My daughter used to carry the strep virus. Rarely showed symptoms, but the rest of the kids would kid it. Her doctor figured it out on the third time. Called her “Typhoid Mary”.
The standard flu virus is viable for 24 hours on a hard surface. The SARS virus for 48 hours. They are still trying to figure this one out. Although I’m guessing they have figured it out - but aren’t telling anybody. Some reports say it is viable 3-6 days or more!!??? I don’t know about that, but I’m almost positive it isn’t just for two hours.
The HIV virus was the lowest number that I found - but it was still something like 4 hours.

HIV cannot survive outside of a host fluid for more than a few seconds. This means if you can't see it, it's not surviving.
In dried or partially dried blood, semen, etc. it can last significantly longer, like 5 days.
Most flu and common cold type viruses are also subject to the same rules, but can last much longer than HIV. Hours, rather than seconds. As to Novel Corona, no one is sure yet, but you can expect it to be as much as a regular flu virus.
My kids kept getting strep throat. We treated the whole family and my son still got it again
Then I figured it out...it was the dog. Antibiotics for the dog and no more strep.
