AIDS transmission - Risk Factors

March 2017


HIV Infection can occur during sex or by blood. The fetus can also be infected by a mother virus. Infected with HIV breastfeeding mother can pass the virus to her baby. The unprotected sex and taking drugs intravenously are the main sources of contamination of the HIV virus.

Which elements can spread the virus?


Blood, semen, vaginal fluid, placenta and breast milk can spread HIV. Saliva, air or direct contact can not transmit the infection. The common use of glasses, cutlery, objects, toilets ... does not allow the spread of the virus.

Sexually transmitted infection


Infection with the HIV virus is a sexually transmitted infection. An HIV-infected person can infect his partners during sex. One unprotected sex is enough to contaminate the partner.

Healthy carrier


A person can be infected with the HIV virus without showing symptoms: this period can be spread over several months or even years. This person is a healthy carrier of the virus, and can transmit it while ignoring his or her partner during unprotected sex. It is impossible to know with certainty whether one is carrying the HIV virus without making a blood test (HIV serology).

Multiple sexual partners


The risk of HIV infection worsens if sexual partners are numerous.

New partner with unknown HIV profile


The risk also worsens during sex with a new partner whose HIV serology status is unknown.

Skin or mucous membranes lesions


A carrier of HIV virus partner with skin or mucous membranes lesions may transmit it more easily.

Unprotected sex


Having unprotected sex with a person you do not know the HIV virus serology is a major risk.

A HIV test in case of risky behavior


The only way to protect themselves and their partners when we adopt risk behaviors, is to do a HIV serology. If positive, it helps to support the person and avoid it transmits the virus through unprotected sex.

Blood transmission


Blood transmission is observed mainly among injecting drug substances intravenously using contaminated with blood from an infected person with HIV equipment . Professionals working in contact with patients (doctors, nurses, caregivers help dentists ...) can also be contaminated accidentally.

Transmission from mother to child


A mother infected with HIV can pass it during pregnancy, childbirth or through breastfeeding.

Do not hesitate to consult


Do not hesitate to contact a doctor, an anonymous and free screening or go immediately to the emergency room if contamination to assess risk and consider an emergency treatment.
