You know that your preventative immune system regimen may have helped me too. Since Covid I take Vitamin C, D3, zinc and Quercetin daily. This year I avoided serious, high temperature flu (no shots either) and had no colds but just an occasional sore throat and my allergies to deal with. If I had been exposed to the hantavirus my immune system may have been strong enough to prevent it from developing into something much more serious. Speculation only.
