Sexually transmitted (STDs)
Any disease which is transferred from one individual to another through sexual activity.
Critical time period
Time during which the infected patient could have acquired and transmitted the disease.
Persons who are not named by the infected patient but who are involved in the epidemiological process due to their close social relationship to the patient, their contacts, or cluster suspects.
All STD patients will be interviewed for epidemiological information on sexual contacts to ensure contact tracing and treatment.
