MOSCOW (Sputnik) – A Russian lymphoma affected person with long-term COVID-19 has acquired 18 mutations of the virus in over 4 months length of the illness, based on the preprint of a examine revealed at virological.org.
The examine, launched in early January, is authored by researchers from the Skolkovo (*18*) of Science and Technology, the (*18*) for Information Transmission Problems of the Russian Academy of Sciences, Pavlov First State Medical University of St. Petersburg, Smorodintsev Research (*18*) of Influenza, and a St. Petersburg metropolis hospital.
The mutations developed in a 47-year-old feminine lymphoma affected person, who goes by Patient S in the examine. Patient S doubtless contracted the virus when she was on deliberate chemotherapy in a hospital.
On April 17, affected person S was discharged from the hospital. On April 30, she examined constructive for COVID-19.
The researchers word that persistently constructive polymerase chain response check for SARS-CoV-2 “occurs in a fraction of COVID-19 patients, and is usually associated with suppressed host immune system.” The virus, they counsel, undergoes “rapid accumulation of mutations” in these people.
