However none worked."We really thought he was going to die," Snell said.So the team crushed up two antiviral treatments not previously used together -- Paxlovid and remdesivir -- and administered them to the unconscious patient via a nasal tube, according to a non-peer-reviewed preprint study on the website ResearchSquare."Miraculously he cleared and perhaps this is now the avenue for how we treat these very difficult persistent infections," Snell said, emphasizing that this treatment may not translate for normal Covid cases.At the ECCMID conference in April, the team announced the longest-known persistent infection in a man who tested positive for 505 days before his death.That "very sad case" came earlier in the pandemic, Snell said, adding that he was grateful there were now so many more treatment options available.dl/ah© Agence France-Presse
