HIV is transmitted through blood, semen, pre-semen (pre-ejaculate), vaginal fluids, and breast milk. These fluids need to enter the bloodstream. Saliva is not generally considered risky, but cuts, sores, or blisters in the mouth increase the likelihood of transmission (i.e., HIV infection). Other bodily fluids such as sweat, tears, or urine are not risky.

During invasive surgical procedures healthcare workers may also come into contact with the following bodily fluids, which contain significant amounts of HIV:

Blood, semen, vaginal fluid, breastmilk, and other body fluids containing blood taken from HIV-positive people can contain high concentrations of HIV. The virus also might be present in the fluid surrounding the brain and the spinal cord, fluid surrounding bone joints and fluid surrounding a fetus of an HIV-positive pregnant woman. HIV has been found in the saliva and tears of some HIV-positive people but in very low quantities.

The solid top of the 3M 3400 Safety-Walk Cushion Mat will not absorb liquids, so spills and body fluids are wiped up easily

Blood, pre-cum, semen, vaginal secretions, and breast milk all contain high concentrations of HIV, and all have been linked to transmission of Saliva, tears, sweat, and urine can have the virus in them, but in such small concentrations that nobody has ever been infected through them.

An infected pregnant woman can transmit HIV on to her unborn baby either before or during birth. HIV can also be passed on during breastfeeding. If a woman knows that she is infected with HIV, there are drugs that she can take to greatly reduce the chances of her child becoming infected, as well as other options such as choosing to have a caesarean section delivery and not breastfeeding, as HIV is found in breast milk.

A blood test can determine whether or not a person is infected with HIV. The most commonly used test detects antibodies (disease-fighting proteins) against HIV. It may take as long as three to six months for HIV antibodies to reach levels that are measurable in standard blood tests.

If you are planning to collect body fluids or tissue, a statement that indicates that persons at increased risk for Hepatitis B or C or HIV (AIDS) infections should not donate blood or other body fluids. In order to locate source subjects quickly, the informed consent document should contain the current address and telephone number of the subject.

During the acute phase, a person can infect others through secretions from the nose and throat. Discharge due to coughing and sneezing can cause the virus to be transmitted easily. Young children who tend to drool can also transmit the infection through the saliva. Until the blisters dry, a person should be regarded as infectious. Fluid from the blisters contains the virus. The virus is also present in the stool for several weeks after symptoms of illness have vanished.

There is no evidence to show that mosquitoes transmit HIV. Epidemiologically, the incidence of HIV infection is the highest among the sexually active group of 15 years to 40 years. However, mosquitoes bite persons of all age groups and if they were a means of spreading HIV, the incidence of infection would be uniformly high and among all age groups.

No. Although this is a common fear, there is no evidence to support the theory that mosquitoes can transmit the Human-Immunodeficiency Virus (HIV). Studies by the US Centres for Disease Control and others can find no evidence that mosquitoes, or any other blood-sucking insect, can transmit HIV. In countries where both high HIV prevalence and high malaria rates exist, such as Uganda, HIV mainly affects the sexually active population.

Yes. Any exposure involving mucous membranes is considered “significant” and immediate irrigation is required. Experts recommend no less than 20 to 30 minutes of continual irrigation with water or saline (although we suggest using Lactated Ringer’s to improve patient comfort), starting as soon as possible after the exposure. Treatment should not be delayed to determine whether or not the patient has an infectious disease.

HIV can be transmitted (passed) from one person to another through sexual contact, needle sharing, during birth, breast-feeding, or infected blood and tissue products. HIV can be found in the blood, semen, vaginal fluids, and breast milk of an infected person.

Studies of families of HIV-infected people have found that HIV is not spread through sharing utensils, towels, bedding, or toilet facilities. Behaviors that increase the likelihood of contact with blood from an HIV-infected person, such as sharing a razor or toothbrush, should be avoided.

A person with HIV can live for many years without showing any outward signs of illness. The majority of persons infected with HIV do not know they have the virus. However, they can infect others. Persons who have been infected with HIV will eventually develop AIDS.

Mosquitoes or other sucking and biting insects do not transmit HIV. For a mosquito to infect someone, it would have to bite a person who was infected. Then, it would have to both immediately travel to someone else and infect that person from tiny drops of infected blood left on the sucker, or it would have to process the virus in its saliva and inject it into the next person. Mosquitoes do neither of these things. They do not travel from person to person.

Yes, if the injecting equipment is contaminated with blood containing HIV. Avoid injections unless absolutely necessary. If you must have an injection, make sure the needle and syringe come straight from a sterile package or have been sterilised properly; a needle and syringe that has been cleaned and then boiled for 20 minutes is ready for reuse. Finally, if you inject drugs of whatever kind, never use anyone else's injecting equipment.
