the treatment on those risk people who would otherwise be hospitalized without any treatment.
Covid virus itself doesn't do much harm to you. It is your one or multiple organs' overreactions after the virus is gone that hurt you, damage you, hospitalize you and even kill you. At that stage HCQ certainly doesn't work. What we were talking about is early stage, i.e. you, risk people, have running nose or fever this morning and went to have a test with a positive result. You should start treatments with those meds (BTW, it is not single medicine treatment). Some doctors already developed early treatment protocol. One doctor in TX has early treated over 1,500 covid patients, prevent 85% of them from going to hospital. Another doc in CA has treated over 2,700 covid patients.
