......
Experts have reduced the protective window of prior infection from 12 weeks to 28 days.
......
Reinfection ...... is on the way up. Reinfection made up 1 per cent of all cases in the pre-Omicron period in England, but in recent weeks it comprised more than 25 per cent of daily cases there and 18 per cent in New York City.
......
people who report no symptoms or have lower concentrations of virus on their polymerase chain reaction (PCR) swabs with their prior infection are more likely to be reinfected than those with symptoms or higher viral concentrations.
This indicates that when the body mounts a more robust immune response to the first infection, it builds defences against reinfection.
......
Most of the discussion of late has been about the immune-evading prowess of the coronavirus. But don’t forget the virus still has to get into our respiratory tract to cause reinfection.
SARS-CoV-2 is spread from person to person in the air by respiratory droplets and aerosols, and by touching contaminated surfaces.
We can disrupt transmission by doing all the things we have been taught over the past two years – social distancing and wearing a mask when we can’t (preferably not a cloth one), regularly washing our hands, improving ventilation by opening windows and using an air purifier for poorly ventilated spaces. And we can isolate when we’re sick.
......
The bottom line is it will be hard to outrun becoming infected or reinfected with a COVID variant in the years to come.
