HIV has only really been known for ~40 years. And for at least 10 to 15 of those years research into treatment was limited and stigmatized as it was considered a "gay disease".

The modern treatment regime was developed around 2010. That is, about 15 years.

I'd argue that with the timeline of the disease that's not recent. What's become more recent is the mass availability of treatment and the significantly reduced cost of treatment.
