In turn, Christian Drosten, a virologist from the Berlin clinic Charite, who advises the German authorities on countering the pandemic, argued that after recovering from COVID-19, a person acquires immunity, which partially protects him from re-infection with the coronavirus. Drosten believes that if it happens, COVID-19 will be less severe.
The first confirmed cases of reinfection in Europe were detected in the last week of August in Belgium and the Netherlands. As virologist Marion Koopmans, quoted by the Dutch public television NOS at that time, said, previously only cases were known when the coronavirus present in the patients’ bodies was present in the body of patients again after the first symptoms of the disease were resolved. In August, scientists discovered cases of patients who were infected twice with two slightly mutated strains of the virus.
A Dutch patient is a person with a weakened immune system. In Leuven, Belgium, a woman who fell ill for the first time three months earlier was re-infected. Also in August, researchers from the University of Hong Kong found the first case of reinfection in an infected patient 4.5 months after recovery.
The article published by Hong Kong scientists shows that although the disease did not protect the patient from reinfection, his body reacted faster, as a result of which he passed it asymptomatically. For a Belgian woman, the symptoms of the disease were mild.
As virologists quoted by Dutch television commented, cases of re-infection with the coronavirus were expected. However, it was not known how long the body remains immune after the infection, which is important in the context of the effectiveness of vaccines against COVID-19.
