I could be wrong, but I have not heard of quinine helping with Wu-Flu. I believe Chloroquine and quinine are unrelated drugs that are both used to treat malaria.
On another note, I hope you are drinking gin with that tonic water.
Growing up in Malaria infested India, my mother forced us to swallow lots of quinine pills. They are really bitter and we kids hated them, but it kept us from getting viral diseases.
