A pill used to treat HIV can also prevent infection, the CBC reports. U.S. health officials say doctors should consider recommending the pill to men and women at high risk of contracting the disease.
Truvada is a drug that is taken daily to treat HIV, but studies have also shown it also reduces the probability of infection. Last month, the Food and Drug Administration approved its use for people having risky sex.
The only problem is that it costs between $6,000 and $12,000 U.S. a year. Not all insurers cover the drug, so condoms are still a better bet. But a U.S. official speculates that this drug might help protect couples who want to have a baby when one of the adults has HIV.
About 65,000 people in Canada are living with HIV.
