It's the first documented case of its kind.
A 90-year-old Belgian woman died in March after contracting two Covid-19 strains, medical researchers in Belgium said Sunday, unearthing the first-known instance of someone simultaneously contracting two different strains of the virus as concerns over infectious new variants mount worldwide. ...
Doctors said they don't know how the woman was infected, but the presence of both the alpha and beta strains, which were first identified in the United Kingdom and South Africa, respectively, was confirmed after scientists analyzed results from the widely used polymerase chain reaction Covid test to look for variants of concern.
It's"difficult to say" whether the co-infection played a role in the quick deterioration of the patient's health, said Dr. Anne Vankeerberghen, a molecular biologist at the hospital, noting the case is the first of its kind to be published. Vankeerberghen urged scientists to analyze a larger proportion of positive Covid test results in an effort to detect variants of concern, saying additional documented cases will be necessary in order to better understand the impact of a Covid-19 co-infection."This is one of the first documented cases of co-infection with two SARS-CoV-2 variants of concern," Vankeerberghen said Sunday.
