The Centers for Disease Control and Prevention (CDC) recommends that everyone between the ages of 13 and 64 get tested for HIV at least once as part of routine health care. For individuals with specific risk factors, CDC recommends getting tested once a year. Anyone participating in high risk activities (E.g. sharing needles for injecting drugs, having sex with HIV positive individuals without the use of a condom) should have HIV testing carried out every 3 months. This frequency of testing would ensure the infection is identified as quickly as possible.
