How is HIV transmitted?
The only way HIV can be transmitted is when a certain amount of the virus gets into the bloodstream. There is no danger of infection through
Using the same dishes, silverware, or glasses
Using the same toilettes, baths, or saunas
Kissing as long as there are no bleeding wounds in the mouth.
Which body fluids contain HIV?
Blood (including menstruation blood) and sperm contain the virus in high concentration. There is a smaller concentration in the vagina fluid but it is still enough for a transmission. Although the virus can be detected in urine, excrement, saliva, sweat, and tears there is no case known where a transmission happened because the concentration is too small.
Which practices are dangerous?
Most frequently the transmission happens via sex without a condom. Especially the intestinal mucous is very sensitive to small breaches which open it for the virus. Therefor, anal sex without a condom is very risky. But unsafe vaginal sex also has a high risk because small unnoticeable lesions in the vagina or the uterus let the virus in the sperm in very easily. And vice versa, very small skin cracks on the penis are dangerous if the vagina liquid or the menstruation blood is contaminated.
The virus is easier to transmit from a man to a woman. During menstruation, the risk of contagion is higher for both. Oral sex is a risk if sperm or menstruation blood gets into the mouth of the partner.
How can I protect myself from HIV?
HIV is not a virus that is transmitted easily. It is very sensitive and is nonviable outside the body. The ordinary hygienic sanctions in household and hospital are enough to stop the virus.
