An elderly woman from Belgium underwent a scientific investigation after it was revealed that she had died of two strains of the SARSCOV2 virus.
More recently, scientists from Brazil have also reported two particular case studies in which two genomic strains of virus were found at the same time in two people who tested positive for coronavirus. of the virus are also isolated cases, but they call into question many similarities.
In the first case in which the elderly Belgian was found to have been infected with two strains of the virus, the alpha variant (which is said to be from the UK) and the beta variant (detected in South Africa). She was hospitalized with an injury and underwent a routine PCR test that diagnosed co-infection. The woman quickly developed respiratory symptoms within 5 days from which she died. The investigation revealed that the woman was not vaccinated.
While these are the few “rare” cases of COVID co-infection reported worldwide, scientists believe that co-infections, particularly those with respiratory viruses, are not at uncommon risk as cases increase. RNA viruses such as influenza and hepatitis C often mutate and are known to cause co-infections.
Because viruses are known to develop and mutate over time, they also lead to mutations that pose a risk to us. While not all mutations are scary, those who are able to bypass the natural immune response are at the highest risk of infection.
