Scientists have announced the world's first death from a coronavirus after re-infection. The fact of reinfection was confirmed by the results of laboratory tests.
Fatal case after reinfection with COVID-19 published in Oxford University Press. An 89-year-old Dutch woman who was being treated for Waldenstrom macroglobulinemia, a rare type of lymphoma, was admitted to the emergency department early in the year with fever and severe cough. The coronavirus was confirmed by a PCR test. The patient spent five days in the hospital, after which almost all respiratory symptoms disappeared, only chronic fatigue remained.
Two months later, a couple of days after starting a new course of chemotherapy, the woman had a fever, a cough and severe shortness of breath. Saturation (blood oxygen saturation) was below 90%, the respiratory rate was only 40 breaths per minute. The coronavirus test was again positive, no antibodies were detected. On the eighth day, the patient's condition worsened, after two weeks she died.
The researchers analyzed samples of the coronavirus in the patient's swabs and confirmed that the genetic makeup of the virus was different. This means that in this case there was precisely a case of re-infection.
Note that to date, only 23 cases of reinfection have been officially identified in the world. Last week, the DNCOM Research Center for Molecular Genetic Research reported confirmed reinfection in a 34-year-old Muscovite, who first became ill in June and then in October. The general director of the center, Andrei Isaev, explained that from the point of view of a scientific approach, only PCR verification can prove a case of re-infection.
However, last Saturday, the head of Rospotrebnadzor, Anna Popova, announced that there were no confirmed cases of re-infection in Russia.
