Coronavirus doctor's diary: Will Covid be with us forever,
like flu?
The antibodies that protect against infection with Covid-19 fade over time, so it's likely
that vaccination will not provide a permanent defence. Covid could become an illness
like flu, says Dr John Wright of Bradford Royal Infirmary - one that flares up in society
at regular intervals, and that people have more than once.
Four million people in the UK have now tested positive for Covid and one of
the burning questions they are asking is: will they get it again? Some viral infections
such as measles, mumps or chickenpox only infect us once. They trigger an immune
response that provides a lifetime of antibody protection. Some viruses such as flu
are masters of disguise, mutating rapidly to escape the detection from our immune
surveillance. Other viruses like the common cold, and other endemic coronaviruses,
have forgettable faces that fade from our immune memory and come back to visit us
year after year.
Just before Christmas I wrote about my surprise at having a possible reinfection with
Covid.With 100 million people infected worldwide the number of reinfections appeared
to be vanishingly small.
