ArabiaWeather - A new study, the results of which will be presented at the upcoming ESCMID global conference in Barcelona, Spain, shed light on the “longest-suffering” case of the new Corona virus.
The study focuses on the risk of the emergence of new immunoresistant variants of the SARS-CoV-2 virus in immunocompromised patients. According to the researchers, they described the evolution of the virus over a period of 613 days in a patient with SARS-CoV-2 infection, resulting in the emergence of a new, highly pathogenic variant. Mutation.
The 72-year-old Dutch man was hospitalized in February 2022, and never recovered from the virus until he died in October last year. His 20-month infection with “high viral loads” is believed to be the longest in the history of medical records, although... Recording previous cases for hundreds of days.
Doctors confirmed that the man had a history of leukemia, and had undergone aggressive treatment that depleted B cells, including those that normally produce antibodies to “Covid-19.”
Although most patients clear their Covid-19 infection naturally within a few weeks, the man, whose identity has not been revealed, had a weak antibody response, despite receiving multiple Covid-19 vaccines. Although he received antibody treatments, he showed no response to these treatments when he was admitted to the hospital.
He was called to the hospital repeatedly; Due to episodes of severe symptoms, persistent infection with SARS-CoV-2 has resulted in long periods of isolation during hospital admissions.
The story ended with the patient, whose name was not revealed, harboring a new, unique variant of the virus, as a result of its ability to mutate for a long period within his body and despite there being no evidence that this new variant was transmitted to anyone else.
Researchers confirmed that the virus mutated about 50 times inside the patient's body, which ultimately led to the production of a new immune-resistant variant. Because of its extensive development within the host.
They warned that cases like this pose a significant risk to people's health, as they could lead to the emergence of new and deadly strains of the disease. Ultimately, the patient died in the fall of 2023; Due to the worsening of the underlying blood disorder he was suffering from.
