An international research team has identified a highly virulent and infectious strain of HIV that has been circulating in the Netherlands. If left untreated, this viral strain leads to a much higher level of virus in the blood and a doubled rate of decline in key immune cells compared with the typical HIV disease progression. However, the mutations found in the new variant don’t make it resistant to existing HIV drugs.
Recently, some people have been suggesing that viruses evolve to become less virulent over time. but this shows that this is not always the case. Reports that infections with the Omicron variant of SARS-CoV-2 tend to cause mild COVID-19 symptoms have fuelled the narrative that the virus is becoming less deadly.

Highly virulent HIV variant found circulating in Europe
The mutated strain’s effects are more severe, and it is more transmissible — but drugs are still effective against it.
