HIV is spread by sexual intercourse, including vaginal, anal and sometimes even oral sex. It's most commonly caught by having sex without a condom.
It can also be spread by sharing needles, receiving surgical treatment in countries where sterilization standards are low, and sometimes a mother can pass the virus onto her baby during the birth process or by breast feeding.
