Q1: How different is COVID-19 from SARS and H1N1?
In SARS, we saw a lot of transmissions and about 15 per cent of deaths. For H1N1, it was very rapid transmissions, but deaths were much lower. In COVID-19, we see a mix. Transmission is probably more effective than H1N1, and deaths are slightly higher than influenza but much lower than SARS.
Q2: Will the coming warmer weather make a difference?
We realise from SARS studies that the virus does not like hot weather and humidity. As the months get warmer and more humid, the survival of the virus will be poorer, resulting in poorer transmission person to person.
Q3: Will shutting off the aircon and opening the windows help?
This is a great, energy efficient way to reduce infection risks. The humidity and warmer air will protect you against the virus.
