Will the AIDS pandemic worsen again?
A 63-nation survey funded by WHO and the Bill & Melinda Gates Foundation found anywhere from 6 to 11 percent of new infections involved drug-resistant forms of HIV, and the trend was dire, with resistance increasing as high as 23 percent annually. Once individuals were put on their daily treatments, in 2017 failure rates due to drug resistance were as high as 90 percent in some countries, meaning new infections in those regions could no longer be controlled with the $75-a-year first-line therapies. The first such survey conducted in Cameroon, recently published, found that the majority of patients failing their primary treatments—up to 88 percent of them—were infected with resistant strains of HIV, and overall drug resistance rates in the West African nation in 2018 approach 18 percent.
Meanwhile, preventing HIV infection has fallen off the priority list, both in funding and individual action.
