HIV & AIDS. Is this condition still relevant? What are the latest statistics on this condition and can the new drugs really prevent new infections?

They're still VERY relevant.

Explanation:

In 2019, an estimated 34,800 new HIV infections occurred in the United States. HOWEVER new HIV infections declined 8% from 37,800 in 2015 to 34,800 in 2019. In 2012, the US Food and Drug Administration gave the green light to using daily pills of an HIV medication called Truvada (emtricitabine/tenofovir) to prevent infection. It proved more than 85% effective when taken on schedule. New drugs are still being developed, here's a link from the

FDA explaining some different types of new TREATMENT medications:
