The patient, whose identity has not been revealed, had first tested positive in mid-2020 and had respiratory problems. He remained positive in all tests (about 45) until his death, 505 days later, Dr. Gaia Nebbia, co-author of the study, told Agence France-Presse on Friday.

This is the longest known case of COVID-19 infection, according to a press release from the European Congress of Microbiology and Infectious Diseases, which takes place in Lisbon from April 23 to 26 and where the study will be presented.

The latter, conducted by researchers from King’s College London and Guy’s and St Thomas’ London Hospital, looked between March 2020 and December 2021 on the case of nine immunocompromised patients with persistent infection with the virus.

All tested positive for at least eight weeks, and two tested positive for over a year. Of the nine patients, four died and four eventually recovered. A last patient was still infected at the beginning of 2022, 412 days after being declared positive for the first time.

Immunocompromised patients with persistent infection have little chance of survival, and new treatment strategies are urgently needed to end their infectionsaid Ms. Nebbia.

The study aimed to study the mutations of the virus in infected patients for months. In one of the patients, the virus carried 10 mutations that appeared separately in several major variants, including Alpha, Gamma and Omicron.

We wanted to characterize the viral evolution in these individuals who could accumulate mutations during their persistent infection. This is one of the hypotheses for the emergence of variantsexplained Ms. Nebbia, pointing out that mutations of the virus were observed in five of the nine patients.

According to Office for National Statistics estimates released on Friday, 38.5 million people had COVID-19 in the UK between the end of April 2020 and mid-February 2022, or 70% of the population.
