Researchers identify viral suspects that could be fueling long COVID

Scientists are uncovering a new possibility behind long COVID’s stubborn symptoms: hidden infections that awaken or emerge alongside SARS-CoV-2. Evidence is mounting that viruses like Epstein-Barr and even latent tuberculosis may flare up when COVID disrupts the immune system, creating lingering fatigue, brain fog, and other debilitating issues.

According to the authors, 44 countries have seen tenfold increases in at least 13 infectious diseases compared with levels observed before the pandemic. One idea they discuss, known as “immunity theft,” proposes that an episode of acute COVID may leave people more susceptible to other infections.

wow

Interesting. I wonder what the implications are for ME/CFS research.
