Sexually Transmitted Infections (Diseases) or Venereal Diseases (VD) are diseases that are passed on from one person to another through sexual contact, and sometimes by genital contact – the infection can be passed on via vaginal intercourse, oral sex, and anal sex.
STIs are a major public health problem in both resource-rich and limited conditions. STIs are frequently asymptomatic and can lead to various complications. The immediate goal of screening for STIs is to identify and treat infected person(s) before they develop complications and to identify, test, and treat their sex partners to prevent transmission and reinfections.
