"How Is The Transmission Of HIV Virus Transmitted?" |
| June 27 is National HIV Testing Day in America One in five Americans living with HIV are unaware of their status, meaning that they are not receiving the vital support they need to stay healthy and live longer.

HIV virus infection trasmission is by sexual contact with an infected person, transmitted by sharing needles and/or syringes (primarily for drug injection)
with someone who has the disease, or, less commonly (and now very rarely in countries where blood is screened for HIV
antibodies)
, through transfusions of infected blood or blood clotting factors. Babies born to HIV-infected women may become infected before or during birth or through breast-feeding transmission after birth.

There has been only one instance of patients being infected by a health care worker in the United States; this involved HIV transmission from one infected dentist to six patients. Investigations have been completed involving more than 22,000 patients of 63 HIV-infected physicians, surgeons, and dentists, and no other cases of this type of transmission have been identified in the United States.
Some people fear that HIV transmission might be transmitted in other ways; however, no scientific evidence to support any of these fears has been found. If HIV transmission were being transmitted through other routes (such as through air, water, or insects), the pattern of reported AIDS cases would be much different from what has been observed.
For example, if mosquitoes could transmit HIV infection, many more young children and preadolescents would have been diagnosed with AIDS.

All reported cases suggesting new or potentially unknown routes of transmission are thoroughly investigated by
state and local health departments with the assistance, guidance, and laboratory support from
CDC.
No additional routes of transmission have been recorded, despite a
national sentinel system designed to
detect just such an occurrence.
What body fluids transmit HIV?
These are additional body fluids that may transmit the virus that health care workers may come into contact with:
Kissing
In 1997, CDC published findings from a state health department investigation of an incident that suggested blood-to-blood transmission of HIV by a human bite. There have been other reports in the medical literature in which HIV appeared to have been transmitted by a bite. Severe trauma with extensive tissue tearing and damage and presence of blood were reported in each of these instances. Biting is not a common way of transmitting HIV. In fact, there are numerous reports of bites that did not result in HIV infection. Saliva, Tears, and Sweat HIV has been found in saliva and tears in very low quantities from some AIDS patients. It is important to understand that finding a small amount of HIV in a body fluid does not necessarily mean that HIV can be transmitted by that body fluid. HIV has not been recovered from the sweat of HIV-infected persons. Contact with saliva, tears, or sweat has never been shown to result in transmission of HIV. Insects From the onset of the HIV epidemic, there has been concern about transmission of the virus by biting and bloodsucking insects. However, studies conducted by researchers at CDC and elsewhere have shown no evidence of HIV transmission through insects--even in areas where there are many cases of AIDS and large populations of insects such as mosquitoes. Lack of such outbreaks, despite intense efforts to detect them, supports the conclusion that HIV is not transmitted by insects.
Although HIV has been transmitted between family members in a household setting, this type of transmission is very rare. These transmissions are believed to have resulted from contact between skin or mucous membranes and infected blood. To prevent even such rare occurrences, precautions, as described in previously published guidelines, should be taken in all setting "including the home" to prevent exposures to the blood of persons who are HIV infected, at risk for HIV infection, or whose infection and risk status are unknown. For example,
Businesses and Other Settings
Tattooing or body piercing No instances of HIV transmission through tattooing or body piercing, although hepatitis B virus has been transmitted during some of these practices. One case of HIV transmission from acupuncture has been documented. HIV could be transmitted if instruments contaminated with blood are not sterilized or disinfected between clients.

How do people get HIV? The number of people in the U.S. with HIV/AIDS is about 1,185,000 and approximately 25% of them are unaware of their infection. A person gets HIV when an infected persons body fluids (blood, semen, fluids from the vagina or breast milk) enter his or her bloodstream. The virus can enter the blood through the linings in the mouth, anus, vagina, penis or through broken skin. Both men and women can spread HIV. A person may show no symptoms and still transfer the virus to others. Pregnant women with HIV can also give the virus to their babies.
Some of the activities that can expose you to the virus include: Unprotected sex. This means vaginal or anal intercourse without a condom or oral sex without a latex barrier with a person who is infected with HIV. Sharing needles with an infected person. some examples include dirty needles used to make a tattoo or in body piercing. Some of the symptoms include: Fever, night sweats, exhaustion, loss of weight, swollen glands and flu like symptoms. More sever symptoms may not appear for months or years.
