Do germs spread faster in hot or cold?

Online Answer
In dry air, the droplets remain smaller and lighter, allowing them to spread further. However, in more humid conditions, droplets can be larger and heavier, making them fall to the ground faster. On the other hand, hot temperatures are more likely to kill viral germs.

The risk of catching the COVID-19 virus from the faeces of an infected person appears to be low.

There is some evidence that the COVID-19 virus may lead to intestinal infection and be present in faeces. Approximately 2−10% of cases of confirmed COVID-19 disease presented with diarrhoea (2−4), and two studies detected COVID-19 viral RNA fragments in the faecal matter of COVID-19 patients (5,6).

However, to date only one study has cultured the COVID-19 virus from a single stool specimen (7). There have been no reports of faecal−oral transmission of the COVID-19 virus.
