HIV stands for the Human Immuno-deficiency Virus. It is a virus that only affects humans and which damages the immune system (makes it deficient) and reduces its ability to fight everyday infections.
When someone is infected with HIV, the virus attaches onto the specific cells in the immune system that help protect us and keep us healthy. It eventually kills off these cells weakening the immune system so that it is unable to fight off infections and other illnesses
AIDS Stands for Acquired Immune Deficiency Syndrome. AIDS is a later stage of HIV infection, during which time someone who has the HIV virus develops frequently potential fatal infections and cancers.
Although there is currently no cure for HIV or vaccine available to prevent infection, there are now effective drug treatments that are designed to reduce the amount of HIV in the body, keep the immune system as healthy as possible and help people living with HIV to have long and healthy lives.
These treatments are proving very effective in preventing the development of AIDS related illnesses in people living with HIV.
HIV is present in most bodily fluids of infected people. However, in order for HIV to be transmitted from one person to another there has to be a good quality and quantity of virus in a bodily fluid.
Blood, semen, vaginal fluids and breast milk can all have the right quality and quantity of virus to be infectious but there also needs to be a route of transmission for the virus in these fluids to get into someone’s body.
If someone has HIV, there is not enough HIV virus in their other bodily fluids such as sweat, saliva, tears, nasal mucus, ear wax or urine for these bodily fluids to be infectious. There is absolutely no risk of HIV transmission from coming into contact with any of these fluids.
The main routes of transmission of HIV are:-
Note*: The development of anti-HIV medication means that the risk of vertical transmission of HIV from mother to baby has been dramatically reduced. This means that most HIV positive women who have access to this treatment have given birth to HIV-negative children. The chances of women on treatment having a baby with HIV is very low ( under 1%).
It is not possible to become infected with HIV through:-
HIV prevention refers to practices done to prevent the spread of HIV. HIV prevention practices may be done by individuals to protect their own health, the health of their partner(s) and the health of those in their community, or may be instituted by governments or other organisations as public health policies.
Effective methods of HIV prevention include:-
Note* – HIV treatment works by reducing the level of HIV in the body and when this happens, the chances of passing HIV on to a partner are significantly reduced. This does not mean that HIV treatment is a replacement for condoms, but it does give HIV positive people more options for safer sex and reduces overall risk of onward transmission. The earlier HIV is detected, the more likely the treatment will be successful.
