People who cares about the risk of infection
can take treatment medicines to prevent

Pre-exposure prophylaxis (or PrEP) is the method that people without HIV take medicines daily to lower their chances of getting infected. If we interpret the term of TasP as that the advancement of treatment can be utilized in prevention, PrEP can be considered as one type of TasP.

However, the target of PrEP is people who have consideration of HIV risk, so PrEP is different from U=U, which is aimed at suppressing the viral load of HIV positive people.

From a global view, PrEP has been reported to be of great efficiency on preventing HIV infection, and the introduction of PrEP as a preventing approach has started in Asia as well.

In Japan, there are already MSM* people who started using PrEP as a safety practice, the research group in the Ministry of Health, Labour and Welfare has also started working on the essentiality investigation of promoting PrEP.
