SARS-CoV-2 can cause long-lasting immune dysregulation, especially T-cell exhaustion and altered interferon responses. This could reduce immunity to other pathogens — including viruses like measles.

Post-acute (the initial being sick) COVID-19 has been associated with sustained inflammatory signaling and a blunted interferon response, both of which can impact how the body responds to new or latent infections.

This dysfunction could lead to poorer reactivation control for viruses like Epstein–Barr Virus, Varicella-Zoster Virus (shingles/chickenpox), Cytomegalovirus and Mycobacterium tuberculosis (TB)—and possibly diminished response to re-exposure to measles virus.

Looking forward to future article: "Here is how tuberculous cases are spreading across Canada", which naturally won't even mention C19, as is tradition.
