"The behaviours associated with HIV transmission are highly stigmatized, and that can result in individuals in certain populations not wanting to come forward and be tested," says Paul Sandstrom, director of the National HIV and Retrovirology Laboratory in Winnipeg.
"It remains a problem domestically here in Canada. The epidemic is not over. There are still people at risk. There are still populations that are more vulnerable in Canada. There are still people who are undiagnosed," Sandstrom says.
