Sexually Transmitted Infections (STIs)

Sexually Transmitted Infections (STIs) are caused by micro-organisms such as viruses or bacteria that are transmitted through sexual contact, particularly vaginal, oral or anal sex. According to the World Health Organization, each year, there are over 350 million new cases around the world.

We provide public health workers with expertise, support and resources for the prevention and control of STIs.
