I was just wondering... everyone has been mentioning excessive demand on health or social services in Canada. But, no one mentioned danger to public health or safety, wouldn't HIV fall under this category? or our both of these waived in the family class? I just assumed that is why the medical checks for HIV hepatitis,syphilis,TB etc... cus these are commutable disease that cause outbreaks and serious illness/death if not treated.
No - HIV does not fall into this category. HIV can only be transmitted by s*xual contact, needle sharing, blood transfusions, etc. Because transmission is so limited, you would never have an HIV "outbreak". TB, on the other hand, is transmitted extremely easily in comparison and that's why it is flagged as a danger to public health and safety. People with TB are not allowed to immigrate to Canada (even through spousal sponsorship) until the TB has been fully treated and cured.
