UK man infected with new crown for 505 days…
p>
Doctors in the UK have found the world’s first case of a person known to carry the new coronavirus for more than a year, reaching 505 days.
According to the Guardian, the patient has now passed away. The patient was infected with the new coronavirus in 2020, possibly because of a weak immune system. During the 505 days of continuous observation before his death, it was found that his new coronavirus test has always been positive .
Previously, the longest known case of the new coronavirus was an American cancer survivor in his 40s. Her positive Covid-19 test went on for 335 days.

COVID-19 keeps mutating in patients
< p>Up to 10 mutations
Researchers from King’s College London and the Guy and St Thomas NHS Foundation examined nine patients with refractory COVID-19. Patients were followed up to see how the virus evolved during infection.
In general, COVID-19 infections usually last around 10 weeks, but two patients had the virus for more than a year.
In addition to the patient who was infected for 505 days, one patient has tested positive for 412 days to date and is likely to be more than 505 days old at the next test. Record. Last summer, a 72-year-old patient was also positive for the new crown for nearly 10 months.
New research indicates that patients with weakened immune systems are particularly susceptible to long-term infection with the new coronavirus. Four of the nine patients studied died, probably less than half of them directly from the virus.
Dr. Snell, one of the researchers, pointed out that persistent infection may be the source of new new coronavirus variants, because the virus also continues to evolve in the patient’s body and may acquire it at any time. new mutation.
Genetic analysis showed that five of the nine patients had at least one mutation in the virus, and patients who had been infected for 505 days had more virus. It carries 10 mutations, including several major variants including Alpha, Gamma and Omicron from the outside..
Many scientists suspect that worrisome variants, such as Omicron, are present in patients with persistent infections, and other new variants are possible Sourced here.

The virus lurks deep in the lungs
The throat swab was undetectable
What worried them most was that one patient in the study had been suffering from an “occult” infection.
Unlike asymptomatic infected individuals, “occult infected individuals” tested negative for COVID-19 despite continuing to carry COVID-19.
After contracting COVID-19 in 2021, the patient’s symptoms subsided after treatment and multiple tests were negative thereafter. Snell said the virus may be lurking deep in the patient’s lungs and swabs from the nose and throat could not detect it.
Paul Hunter, professor of medicine at the University of East Anglia, said that in light of the study, he thinks there may be some patients who have never completely cleared the virus from their bodies. This is one of the reasons why new variants of the virus appear repeatedly.
