Thirty years of HIV

It’s been 30 years since scientists announced the cause of aids a retrovirus that would become known as HIV.

By the time the cause was announced on April 23rd, 1984, more than 1700 Americans had already died from the rare infections and cancers caused by the human immunodeficiency virus, and hundreds of Canadian cases of aids had been reported.

Researchers are still trying to find a vaccine to prevent HIV, but advances in treating the infection have led to a steep decline in aids deaths.

An estimated 35 million people are living with HIV worldwide.
