Brussels, July 11 A 90-year-old unvaccinated girl in Belgium has died after being concurrently contaminated with Alpha and Beta two completely different variants of concern (VOCs) of Covid-19, researchers have mentioned. The case advocates the must be alert to co-infections.
A workforce of researchers from the OLV Hospital in Aalst, introduced the nonagenarian girl’s case on the ongoing 2021 European Congress of Medical Microbiology and Infectious Ailments, going down on-line between July 9 and 12.
“This is without doubt one of the first documented instances of co-infection with two SARS-CoV-2 variants of concern,” mentioned lead creator and molecular biologist Dr Anne Vankeerberghen from the OLV Hospital.
“Each these variants have been circulating in Belgium on the time, so it’s doubtless that the girl was co-infected with completely different viruses from two completely different individuals. Sadly, we do not understand how she turned contaminated,” Vankeerberghen added.
The workforce reported that the lady, whose medical historical past was unremarkable, was admitted to the hospital on March 3, 2021, after a spate of falls. She examined constructive for Covid on the identical day. She lived alone and acquired nursing care at house, and had not been vaccinated towards Covid-19.
Additional exams for VOCs with PCR confirmed the presence of two completely different strains of the virus Alpha (B117), which originated within the UK, and Beta (B1351), first detected in South Africa.
Initially, there have been no indicators of respiratory misery and the affected person had good oxygen saturation. Nevertheless, she developed quickly worsening respiratory signs, and died 5 days later.
In January 2021, scientists in Brazil reported that two individuals had been concurrently contaminated with two completely different strains of the coronavirus the Brazilian variant generally known as B1128 (E484Okay) and a novel variant VUI-NP13L, which had beforehand been found in Rio Grande do Sul. However the research has but to be printed in a scientific journal. Earlier analysis has reported individuals contaminated with completely different influenza strains.
“Whether or not the co-infection of the 2 variants of concern performed a task within the quick deterioration of the affected person is tough to say,” Vankeerberghen mentioned.
“To this point, there have been no different printed instances. Nevertheless, the worldwide prevalence of this phenomenon might be underestimated as a consequence of restricted testing for variants of concern and the shortage of a easy technique to determine co-infections with complete genome sequencing,” she famous.
