HIV
is found in most body fluids, but it is only infection in blood, semen and
vapiral secretions.
It
is likely that the virus is transmitted when infected cells are in close contact
with white blood cells (which include the T4 helper cells). This situation
occurs when the virus is in the blood stream, but it may be possible that it can
be transmitted to the white blood cells found on the livings of the various
openings of the body such as those in the genital areas.
There
are normally only a few white cells on these livings, but when the livings are
inflamed or damaged then the concentration of the white cells vastly increases
in order to repair the damage and protect against infection. Such a situation
would occur when the living was irritated, infected with some other organisms or
hard been damaged occasionally, an IUO can cause some local inflammation. This
is why IUD are contra-indicated for women who may be at risk of contracting any
sexually transmitted disease from infected partners.
Generally,
HIV is spread by sexual contact with infected person, by sharing needles and/or
syringes (primarily for drug injection) with someone who is infected, or, less
commonly (and now very rarely in counties where blood is screened for HIV
antibodies), through transfusions of infected blood or blood clothing factors.
Babies
born to HIV infected women may become infected before or during birth or through
breast-feeding after birth. In the health care selling, workers have been
infected with HIV after being stuck with needles containing HIV-infected wood
or, less frequently, after infected blood gets into worker’s. Open cut or a
mucous membrane (fro example, the eyes or inside of the nose).
Some
people fear that HIV might be transmitted in other ways; however, no scientific
evidence to support any of these fears has been found. If HIV were being
transmitted through other much different way e.g. mosquitoes, 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.
Environmental
scientist and medical authorities agree that HIV does not survive well in the
environment, making the possibility of environmental transmission remote. HIV is
found in varying concentration or amounts in blood, semen, vaginal fluid,
breast milk, saliva, and tears.
