Sexually Transmitted Infections

Muhtasari

Some infections spread mainly through sexual contact, and one of them, HIV, can quietly disarm the body's own defences over many years. Understanding how it is passed on, and how it is not, is the key to stopping it and to clearing up the fear and myths that surround it.

In this lesson you will define a sexually transmitted infection, name HIV as the pathogen that can lead to AIDS, describe exactly how HIV is transmitted, and explain the practical ways the spread of sexually transmitted infections is controlled.

State that human immunodeficiency virus (HIV) is a pathogen that causes an STI

Maelezo ya Somo

Sexually transmitted infections are a major public-health issue, and HIV in particular has shaped global health policy. Knowing the real routes of transmission lets people protect themselves and avoids stigmatising those infected, since HIV is not spread by everyday contact.
