Unprecedented 613-Day COVID-19 Infection in Elderly Patient Leads to Over 50 Mutations

In a striking discovery, Dutch researchers have documented the longest-known case of a COVID-19 infection in a 72-year-old patient, who harbored the virus for 613 days. During this extended period, the virus accumulated more than 50 mutations, shedding light on the potential for severe and prolonged infections in immunocompromised individuals.

A remarkable case study conducted by the University of Amsterdam’s Centre for Experimental and Molecular Medicine has unveiled a COVID-19 patient with a compromised immune system, who nurtured a highly mutated strain of the virus for nearly two years. The patient, a 72-year-old man suffering from a chronic blood disorder, exhibited minimal immune response despite receiving multiple COVID-19 vaccinations.

Detailed examinations of the patient’s samples, collected via numerous nasal and throat swabs, revealed that the coronavirus swiftly developed resistance to sotrovimab, an antibody treatment administered to combat the disease. Over the course of the infection, the virus underwent significant genetic changes, acquiring mutations that enhanced its capacity to dodge immune defenses.

This prolonged infection, which is the longest recorded to date, was the focus of the Dutch research team’s presentation at an upcoming medical conference in Barcelona. Their findings underscore the critical need for continuous genomic surveillance, particularly in patients with weakened immune systems, to monitor the evolution of the virus and the emergence of new variants that could pose public health risks.

Additionally, ongoing studies of genomic data from community wastewater samples indicate that other individuals may also be unknowingly harboring heavily mutated viruses. These findings are pivotal as they link persistent infections not only to the potential development of new virus strains but also to the prolonged suffering of patients with long COVID symptoms, further emphasizing the complexities of managing and understanding this global pandemic.
