The number of new cases of HIV in the Saskatoon Health Region has dropped for the third year running.

Since its peak in 2009, when it reported 200 new cases, the number of new cases of the virus have gone down by almost 50 per cent.

Johnmark Opondo is the region's medical health officer.

He said more HIV patients are on anti-viral medication.

"And what the anti-viral treatment does is it lowers the amount of virus in your blood, and that way making individuals less infectious," he said.

Opondo said outreach workers have played a big part in the decline of HIV.

He said they help patients with issues such as transportation and housing, and that makes treating the patients much easier.
