even the WHO got it wrong in the early stages.
The hard surface story was a confusion. Many stated the incorrect fact based on other viruses.
If you search my older posts, when this issue was first raised, I stated that Corona viruses are different and can stay active for 28 days at 4 Deg C, 2 days on currency notes, 4 days on stainless steel and only for 15 mins at -65 Deg C (minus)
At that time nobody had tested the Covid. The figures i gave was based on research on the SARS virus (2003) - because both are similar.
The only ever instance a cat was suspected, was the famous Amoy Gardens Apartment incident in HongKong - 2003. But later it was found that it was not really the cats.

The correct answer is that the survival of a virus on hard surfaces is dependent on several factors. The two main environment factors are the air temperature and the relative humidity. This is fairly obvious.
As the temperature goes up survival becomes less and as the relative humidity goes up, the survival rate of the virus goes up too.
It has been observed at 4°C, infectious SARS-CoV virus persisted for as long as 28 days.
But don't get scared - this is not the usual and they become inactive after 24 to 48 hrs depending on the type of surface too. Studies show that on currency notes it can survive for two days..
The best surface for killing viruses is our skin. In the cases of both common flu and cold-causing viruses, infectious particles on our hands are usually gone after 20 minutes.
