"At the end of the third year of the pandemic, we are no longer surprised to
hear we’re in a new wave of infection. It’s fuelled by new sub-variants of the
virus that may evade immunity from both vaccination and previous infections.
Authorities recommend control measures, but they are “voluntary”. They include
wearing a mask, vaccination, testing if you have symptoms and staying home if
you test positive, and ventilation. Ventilation is often the last measure
listed – as if it’s an afterthought.
While vaccines are highly effective in reducing the risk of death and serious
illness, they are generally not effective in preventing transmission. Wearing a
mask reduces the risk of both spreading and acquiring an infection but only
when worn properly.
The best way to reduce the risk of transmission is to reduce the concentration
of airborne virus that is available to be inhaled and can therefore cause
infection.
Adequate ventilation of air in indoor spaces is the key to achieving this goal
and should be at the top of the list of control measures. Ventilation reduces
the risks for everyone, regardless of other individual actions."
