more saskatchewan residents were diagnosed with hiv in 2021 than any year prior, a setback in a decades-long fight to get the province’s sky-high transmission rates under control.
the province, which already had the highest rates of the virus in canada, reported 237 new cases last year — a record total doctors say shows worsening inequities that abet hiv’s spread.
dr. johnmark opondo, a top public health physician, said the covid-19 pandemic hampered access to care including hiv testing. but, he says, the high case loads are not only a reflection of delayed diagnoses.
“i think if we blame it all on that, that’s a misrepresentation,” said opondo, a medical health officer with the saskatchewan health authority.
“i also believe our transmission dynamics have intensified. this increase in numbers is not just artifactual catching up in testing.”
saskatchewan’s hiv transmission rates are routinely two to three times the national average and the highest in the country.
it is the only province where injection drug use — not sex — has historically been the leading cause of transmission. in 2021, the provincial ministry said half of people newly diagnosed with hiv reported injecting drugs, a significantly lower percentage than previous years. sexual contact was identified as a risk factor in 68 per cent of new cases. the two are not mutually exclusive.
“heterosexual transmission has actually emerged and become more and more of a factor,” opondo said.
he cautioned it was too soon to call it a change in how the virus spreads and stressed injection drug use is likely still the primary driver of new cases.
some frontline doctors, though, say they’ve noticed a real shift in who the virus is affecting.
“isolating this illness to be amongst drug users is not an appropriate way to interpret this information,” said dr. larissa kiesman, a physician at saskatoon’s westside community clinic, a hub for hiv care.
