A study said that a man who had been having chronic bronchitis for more than 400 days was cured.

A man had a suppressed immune system because of a transplant. The Washington Post reported on November 4 that he had the disease for at least 411 days.

The man had the same strain of COVID-19 that he had at the beginning of his illness.

"Now, everyone is infectious with omicron, but when we looked at his virus, it was something that existed a long time ago," said a physician studying the evolution of viruses at Guy's and St Thomas'.

He said that it was an older variant from the beginning of the Pandemic.

The patient was paucisymptomatic, meaning he didn't have any of the symptoms of COVID-19. He had other symptoms that were not life threatening.

He wasn't able to access anti-COVID-19 treatments because his symptoms were mostly mild.

The doctor cured the patient by giving him anti-COVID-19. There was a case reported in the journal.

The patient's case is characteristically long, but not the longest ever.

The longest documented case at the time was the case of a patient who had COVID-19 for over 500 days before their death.

Patients with long-term COVID-19 infections tend to catch the virus when their immune system is weak. Patients with long covid who cleared the infection early on can have long- lasting symptoms of the disease.

The patients have been looked at by scientists because of the possibility that the virus may be able to change inside of them.

A patient whose immune system was weakened by HIV was the subject of a June 2021 report.
