This is a prospective, 3-year observational study to describe drug utilization in uninfected individuals (UIs) who initiate emtricitabine (FTC)/tenofovir disoproxil fumarate (TDF) (Truvada®) for a pre-exposure prophylaxis (PrEP) indication.

An electronic source of pharmacy/medical encounter information will be used to assess the demographics and other characteristics of the subjects prescribed FTC/TDF or its components in a prospective fashion. The data provider will supply all the de-identified information regarding each visit/interaction that the subject has had with the health system and all the diagnoses and medications that the UI has had prospectively and retrospectively for the length of time captured by the source selected.

200 physicians who prescribe FTC/TDF for a PrEP indication will be sampled from the same source.
