Hi, and thanks for your question
In Canada, hospitals follow strict infection control measures to prevent the spread of infectious diseases. We really do not see HIV acquired from hospital visits in Canada. HIV is most commonly passed through sexual contact or through sharing needles to inject drugs with an infected person.
Have a look at our HIV and AIDS page for more information on how HIV is spread.
