very few diseases in the world are are so dengerous as corona change into superlative

Answer:
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.
“You have got infection control in place, however if you are forever being targeted, on the one rare occasion where your guard slipped, you get infected,” he said. “It is like being in the battlefield – no matter how much protection you have, a stray bullet can catch you sometimes.”
Such a slip, he added, was not surprising. “A minor slip is eminently possible, especially when you are working under stress, you are tired, you have done long hours and your guard falls – and you get infected,” he said.
Repeated exposure puts you more at risk of contracting the virus, but does it make an infection worse?
Pankhania said that at present it was thought there was only one form of the virus in circulation, so doctors were not being exposed to a more serious strain.
But Heymann said that if doctors did become exposed to the virus, it might be in a higher dose than would have occurred in a social context – for example, they might come into contact with bodily fluids. “If there is a massive inoculum of virus, that could make it a more overwhelming infection,” he said.
Corona is one of the most dangerous diseases in the world.
