COVID offers three possible paradigm shifts. If they’re true, and if we actually accept them, so much changes: - Much of disease transmission is airborne - The biggest impact of viruses is chronic disease - Virus exposure harms, not helps, immune systems publichealth.jhu.edu/2022/is-the-...

Does HIV cause of chronic disease; if so- your second one has been accepted for 35 years.

Uh? - respiratory viruses are airborne - what does biggest mean? But yes, médecine has assumed clearance & understudied long term effects of viruses -there was never a model where the immune system was consistently « helped » by pathogens

I'm not sure how these are paradigm shifts. Viruses causing chronic illness is not new information. And no real experts in immunology have claimed viruses were ever good for your overall immune system.
