Normally many flu-like viruses spread by direct or close contact.
Because Virus containing droplets are heavier than air, scientifically it is thought that when someone coughs or sneezes, virus particles quickly fall to ground or surrounding objects.(“like a brick or stone falling to ground“).
But a group of scientists and WHO have raised the possibility that coronavirus can stay in air for longer periods, float around and cause more infections. (“float like a balloon“). This is called air-borne transmission.
What does it mean?
If confirmed– this means “closed spaces” are high risk even if you maintain 2 metre distance from an infected person. AVOID CLOSED SPACES.
As many people in UK do not wear masks in public places, there is a high chance of second wave of infections in the coming weeks as lock down is eased. WEAR A MASK.
It also means avoiding non-essential visitors to hospitals so that visitors cannot catch the infection or pass the infection to vulnerable patients. AVOID NON-ESSENTIAL VISITORS AT HOSPITALS.
If air borne transmission is confirmed, it is also bad news for the coming winter.
If Coronavirus is still in community and not eliminated by winter, air-borne transmission is likely to result in further wave of infections.
This is because Winter means more closed spaces and more chance of infection !!!!!!
