Transmission of STDs

The organisms which cause these diseases (except for crabs and scabies) usually enter the body through mucous membranes, such as the warm, moist surfaces of the:

  • vagina
  • urethra
  • anus
  • mouth

STDs can be caught through intimate contact with someone who is infected, especially during:

  • oral sex
  • anal sex
  • vaginal sex

Some infections are also transmitted non sexually.
