Belgian doctors reported the case of a 90-year-old woman who died in March of COVID-19 and in whom tests subsequently confirmed infection with two new variants of the coronavirus at the same time. According to scientists, this is probably the first documented case of a double infection, which, in their opinion, will not be unique, writes the BBC server.
Doctors also found a variant of the alpha virus, first discovered in Britain, and a beta variant, which was first identified in South Africa. At the same time, they believe that the patient became infected from two different people.
A woman who was not vaccinated first came to the hospital in March due to low blood oxygenation. Tests on her on the same day showed coronavirus, two variants at once.
“Both of these variants were spreading in Belgium at the time, so it is likely that the lady became infected with different types of virus from two different people,” said molecular biologist Anne Vankeerberghen of the Belgian hospital. He is currently conducting research on the case of an unusual patient.
“However, it is difficult to say whether the current infection with two variants played a role in the rapid deterioration of the patient’s condition,” the scientist said. She added that it should be more efforted to find out which variants infect patients.
According to the scientist, no mention of a similar case has appeared in professional journals yet, which does not mean that such cases have not appeared. According to her, this is probably a phenomenon that has not been given enough attention so far. Brazilian doctors also reported similar cases in January, but have not yet published the results of their research.
According to virlogist Lawrence Young, such findings are not surprising. “This study highlights the need to investigate more to determine whether infection with multiple coronavirus variants affects the clinical course of COVID-19 and whether it somehow compromises the effectiveness of vaccination,” he said.
The coronavirus constantly mutates during human-to-human transmission, creating a large number of new variants. Some of them may be more dangerous than previously prevalent versions of the virus, either by greater mortality or, for example, by the ability to bypass the immunity that vaccinated people give.
The World Health Organization (WHO) has so far declared four of these options to be particularly worrying and has begun to call them Greek letters. In many countries around the world, the delta variant, first discovered in India, is now responsible for the new increase in infections.
