My brother-in-law is infected with HIV. I have lived with my sister and brother-in-law for half a month. I'm a little worried and don't know where to test.

Hello, you can go to Baiyun District CDC to test hiv antibody, which is free.

Remedial measures? I won't start using them now,

I think the possibility that you are infected is very small, almost non-existent.

HIV is not transmitted through daily contact.
