Man gets Covid twice and second hit 'more severe'


A man in the United States has caught Covid twice, with the second infection becoming far more dangerous than the first, doctors report.

As countries endure a second wave of the virus, we may start to get clearer answers. It had been assumed that a second round of Covid would be milder, as the body would have learned to fight the virus the first time around. It is still unclear why the Nevada patient become more severely ill the second time. Prof Paul Hunter, from the University of East Anglia, said the study was "Very concerning" because of the small gap between the two infections, and the severity of the second.

"Given the fact that to date over 37 million people have had the infection, we would have expected to have heard of many more incidents if such very early reinfections with severe illness were common."It is too early to say for certain what the implications of these findings are for any immunisation programme.
