Not hotness that kill virus in summer
A lot of idiots such as Donald Trump, and most journalists always contribute to the hotness of summer as the reason for the less transmissivity of flu or any virus.

These are just ridiculous because it also occurs in Singapore and Malaysia. During the SARS period, Malaysia and Indonesia was least affected so the conclusion was that it was due to the hot weather but Singapore is also hot. The difference between Singapore and Malaysia in those days was the lack of shopping malls and hospitals that were air-conditioned.
So it is not the hotness because to kill any virus you need temperatures close to 100 degree Celsius.
But warm water, above 60 degree, which is the temperature inside our car under the sun can kill virus as well.
So it is the idiots also who said that warm water cannot kill virus.
Of course, hot weather and UV light can kill virus, but it does not mean that they can cure a disease. They certainly slow down the disease enough for our body or doctors to take actions on.
So much for evidence-based decisions that these idiot doctors claimed to be.

Virus survival in stool and urine
But UV can kill many types of virus.

Sunlight has UV especially during mid day. Refer to Accuweather for levels of UV radiation.

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).
- Virus loses infectivity after exposure to different commonly used disinfectants and fixatives.
- 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.
- Heat at 56°C kills the SARS coronavirus at around 10000 units per 15 min (quick reduction).
But UV can kill many types of virus.
