Condoms Have Some Unique Advantages
Condoms can do some things that alternative methods of HIV prevention can't: They can protect against a range of sexually transmitted infections (STIs), especially those like gonorrhea and chlamydia that are transmitted in genital fluids or discharge (they are not quite as effective for STIs transmitted through skin-to-skin contact). They can also prevent unwanted pregnancy.
Other methods including pre-exposure prophylaxis (PrEP) and antiretroviral therapy require prior HIV testing, medical supervision, decent health coverage and taking medication on an on-going basis.
Condoms are much simpler, cheaper and more readily available. They are particularly suitable for individuals who don't have sex often or who need protection only from time to time.
