which are not vaccine substitutes either. They reduce illness in those who become infected, and should be saved for such an unfortunate occasion.Vardoulakis believes vaccination is the base layer of protection for the country. Although it will not prevent viral particles entering your body, it may prevent them triggering an infection.
The tiny ones stay airborne longer, and travel further, but their potential danger depends on the environment, says Vardoulakis. Release them in full sun on a beach, and UV radiation will make the viral particles within them decay more quickly than would happen in a regular meeting room. Their study, which is yet to be peer-reviewed, shows the virus loses 90 per cent of its ability to infect within 20 minutes of becoming airborne. How this happens has implications for where you sit in a room.
At 20 minutes, there is no difference between the two. Unexpectedly, the study found the temperature of the air made no difference to the virus’ infectivity.
