Who is most at risk of contracting coronavirus?
''There have been a number of deaths from the coronavirus among
doctors who are young and, as far as we know, otherwise healthy.
Does this reframe who we thought was at risk?
According to Dr Bharat Pankhania, an expert on communicable disease control at the University of Exeter Medical School, it is not surprising that some young, healthy people die after contracting the virus, noting the risk of infection and even death is not zero for any demographic.
“All of us are at risk, and hence the superlative efforts at keeping containment in place, and keeping the virus from circulating as much as we can do,” he said.
David Heymann, professor of infectious disease epidemiology at the London School of Hygiene and Tropical Medicine, agreed. “This is a new disease in humans, so no-one has immunity– health workers, like everyone else, don’t have immunity,” he said.
Are some people more at risk?
Heymann said that who succumbs to the infection and who shrugs it off is often down to individual differences in the body’s response to the virus.
Some groups have a greater risk than others. “At the moment it appears that people who are at greater risk are the elderly and probably the very young,” said Pankhania.
But, he added, “you cannot have that only the elderly and the very young will die, it is part of the natural history of such infections that we will get deaths across the age ranges … The same pathophysiology can happen in the young as in the old.”
Are doctors more at risk of infection than non-medical staff?
In short, yes. “It is not surprising that fellow clinical colleagues have got infected and some have died,” said Pankhania, noting that medical professionals were in a special situation as they had multiple potential exposures to infection.''
