SARS Coronavirus - probably same advice goes…
"Virus survival in stool and urine
Virus is stable in faeces(and urine) at room temperature for at least 1-2 days.
Virus is more stable (up to 4 days) in stool from diarrhea patients (which has higher pH than normal stool).
Disinfectants
Virus loses infectivity after exposure to different commonly used disinfectants and fixatives.
Virus survival in cell-culture supernatant
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._u
Heat at 56°C kills the SARS coronavirus at around 10000 units per 15 min (quick reduction)."
