A*STAR research has shown scientific proof that it is very important to wear a mask, practice good personal hygiene and social distancing.
A research study was done on the spread of cough droplets, taking into account factors such as the tropical climate here.
Dr Lim Keng Hui, the institute's executive director said: ""The transport of droplets in a tropical climate will be quite different from a temperate climate, which would be drier."
Hence, in Singapore's humid climate, large cough droplets will evaporate partially, leaving behind a smaller droplet - which can then be carried even further by the wind.

The researchers added that in their present simulation, Singapore's safe management measures are effective in mitigating the risk of Covid-19 spread.
Dr Lim said: "Our research has shown scientific proof that it is very important to wear a mask, practice good personal hygiene, social distancing, and ensure the environment is well ventilated, as all these things help to collectively lower the risk of transmission."
