Despite the links between emergencies and HIV vulnerability, agencies' emergency operations have tended to focus on meeting basic needs, providing shelter and food and treating infectious diseases like measles, cholera and dysentery. There are a number of reasons for this. HIV is generally not seen as a priority, and there are more pressing immediate needs in emergencies. In failing to take HIV into account from the earliest stages of the planning and implementation of an emergency response, humanitarian practitioners may unwittingly be exacerbating levels of infection.
