The full form of STI is Sexually Transmitted Infection.
STIs are infections that are primarily spread through sexual contact. This includes vaginal, anal, and oral sex. It is important to note that while the term "STD" (Sexually Transmitted Disease) is sometimes used interchangeably, "STI" is generally preferred by healthcare professionals. This is because a person can be infected with a sexually transmitted infection and not yet show any symptoms of disease. In other words, they may be infected but not yet "diseased."
Understanding the difference is important because an individual can unknowingly transmit an STI even if they feel healthy and have no visible symptoms. Regular testing and safe sexual practices are crucial for preventing the spread of STIs. Many STIs are treatable, and early detection can prevent serious health complications.
