Sexually Transmitted & Blood-Borne Infections Basics 


There may not be a cure for HIV, but it is 100% preventable.

The majority of new HIV transmissions are the result of unprotected and condomless sex and sharing needles for injecting drugs. The good news is there are a number of tools in the prevention toolbox, to lower the risk of transmission.


HIV is transmitted through body fluids:

• Blood

• Semen

• Vaginal and anal fluids

• Breast milk

HIV cannot be transmitted through:

• Saliva

• Tears

• Urine

HIV Testing

Approximately 62,050 Canadians have been diagnosed with HIV at the end of 2018 and 1 in 8 people living with the illness don’t know their status. In Alberta, there were approximately 7702 known HIV diagnoses in 2019, with 252 of these cases being new diagnoses.

Because HIV often doesn’t show any noticeable symptoms for many years after it enters the body, many people do not know they have been infected. Testing is a critical tool in addressing HIV. Regular screening, as a routine part of personal health care, can significantly help reduce the number of new infections in the community.

People often get confused between HIV and AIDS. HIV is something that can be measured. It is a virus that enters the body and weakens the immune system. You can be tested for HIV. AIDS stands for Acquired Immunodeficiency Syndrome. An AIDS diagnosis is a combination of being HIV positive and having one or more opportunistic infections, such as cancer. AIDS is a diagnosis, a medical term to identify illness. HIV and AIDS are two very different things. With adequate support and treatment to keep the immune system strong, people can live well with HIV for many years.
