When our house got hit, I did not have Ivermectin so stuck with Vid D,C Zinc and sipped on Tonic water(w/quinine) for the week, I never really got ill, just a massive sneezing fit one day. Each person is different though, I have been taking low dose of all of the above for months already so, pretty sure my immune system was good to go, just upped the dose a bit for a few days. Be sure you are keeping well hydrated too. You got a lot of info here on thread, please use it and do not over medicate yourself.
