HIV makes infected individuals vulnerable to other infections and cancers. If HIV-infected blood is present in saliva, there may be a risk of transmission. A blood test or series of blood tests can confirm the presence of HIV in an individual. Condoms can reduce the risk of transmission. Intestinal infections comprise a variety of intestinal disorders transmitted through anal-oral sexual activity that can cause diarrhea, blood poisoning and abscesses.
Symptoms can include diarrhea, abdominal cramps and inflammation of the rectum.
Intestinal infections can be treated and cured with antibiotics. Condoms reduce the risk of infection. Pubic lice and scabies occur worldwide and are transmitted through sex and other close body contact, such as the sharing of bed sheets, towels or clothes of an infected person. Symptoms occur when the insects bite or burrow into the skin to lay their eggs. For scabies, severe itching and a rash on fingers, wrists, elbows, abdomen, genitals and ankles, begins 2 to 6 weeks after the first exposure or 1 to 4 days after re-exposure.
