It has to be one of the most invasive questions you could ask somebody before a date: Do you have HIV and if so, how infectious are you?

But in a sign of how many gay men are finding sex through the dating app, Grindr, its programmers are now looking to include members' HIV statuses so users can search according to their disease risk preferences and sexual practices.

In a recent survey, Grindr asked members about their HIV status, including whether their virus was "undetectable" in their blood because of effective treatment, and whether they would like to be able to search the HIV profiles of others. The app, which allows men to find potential partners nearby, also asked if people who are HIV-negative were taking a preventative group of drugs known as PrEP (Pre-Exposure Prophylaxis).

While some may view the possible filter as an efficient way to avoid hurtful rejection upon meeting people, some living with HIV and those who research stigma associated with the disease are concerned it will create or exacerbate discrimination.
