@hopeful33250, Thank you Teresa for your post. I had no idea that 4 diff. strains of the Covid virus have been detected. I'm completely relying on the information coming from our leading infectious disease experts. Opinions and actions shared by non-experts in the field are not only dangerous, because many are desperate to try anything, they are also creating shortages of meds proven to help specific-only conditions and needlessly putting vulnerable people in jeopardy of their lives.
