Brussels, July 11 A 90-year-old unvaccinated woman in Belgium has died after being simultaneously infected with Alpha and Beta two different variants of concern (VOCs) of Covid-19, researchers have said. The case advocates the need to be alert to co-infections.A team of researchers from the OLV Hospital in Aalst, presented the nonagenarian woman's case at the ongoing 2021 European Congress of Clinical Microbiology and Infectious Diseases, taking place online between July 9 and 12."This is one of the first documented cases of co-infection with two SARS-CoV-2 variants of concern," said lead author and molecular biologist Dr Anne Vankeerberghen from the OLV Hospital."Both these variants were circulating in Belgium at the time, so it is likely that the lady was co-infected with different viruses from two different people. Unfortunately, we don't know how she became infected," Vankeerberghen added.The team reported that the woman, whose medical history was unremarkable, was admitted to the hospital on March 3, 2021, after a spate of falls. She tested positive for Covid on the same day. She lived alone and received nursing care at home, and had not been vaccinated against Covid-19.Further tests for VOCs with PCR confirmed the presence of two different strains of the virus Alpha (B117), which originated in the UK, and Beta (B1351), first detected in South Africa.Initially, there were no signs of respiratory distress and the patient had good oxygen saturation. However, she developed rapidly worsening respiratory symptoms, and died five days later.In January 2021, scientists in Brazil reported that two people had been simultaneously infected with two different strains of the coronavirus the Brazilian variant known as B1128 (E484K) and a novel variant VUI-NP13L, which had previously been discovered in Rio Grande do Sul. But the study has yet to be published in a scientific journal. Previous research has reported people infected with different influenza strains."Whether the co-infection of the two variants of concern played a role in the fast deterioration of the patient is difficult to say," Vankeerberghen said."Up to now, there have been no other published cases. However, the global occurrence of this phenomenon is probably underestimated due to limited testing for variants of concern and the lack of a simple way to identify co-infections with whole genome sequencing," she noted.Disclaimer: This post has been auto-published from an agency feed without any modifications to the text and has not been reviewed by an editor
