The events of co-infection, or the development of two strains of the virus at the same time, are separate events, but the questions in question have a lot of similarities.
In the first case, in which a Belgian older woman was found to have contracted two virus strains—the alpha version (first originated in the United Kingdom) and the beta version (found in South Africa). The woman, who was admitted to the hospital due to injury, went for routine PCR test, which detected co-infection. The woman rapidly developed respiratory symptoms within 5 days, and died as a result. Investigation revealed that the woman had not been vaccinated.
Thus it became one of the first documented cases of COVID contagion globally. Further findings showed that the woman had contracted the virus when both strains were in circulation throughout Belgium.
However, this is not the first time that cases of coincidence have been reported. Months ago, scientists focused on patients in Brazil who were found to test positive for two different forms of anxiety, including the gamma variant.
In contrast, unlike the Belgian woman, patients in Brazil had less severe outcomes, did not appear to have been affected by the types of concerns, and recovered without the need for hospitalization.
Another case of contagion from Portugal affected a patient who was recovering from a pre-existing COVID-19 infection and was caught with another variant. This, the researchers think, results in prolonged viral shedding and dire consequences for the patient, a teenager with healthy consequences.
