Students at a Chinese university now have the option to test themselves for HIV at their convenience, as they can now purchase affordable testing kits in vending machines.

The urine test kits cost approximately $4.40 and are sold next to instant noodles and other snacks at Southwest Petroleum University in Nanchong City in southwestern China. According to AsiaWire, this move signifies the Chinese government’s newfound urgency in battling HIV, which is on rapid rise among the country’s youth. There are over a half a million people living with the disease in China, according to the Joint United Nations Programme on HIV/AIDS (UNAIDS).

There was a 43 percent year-over-year increase in infection rates among young students and 80 percent of those occurred from same-sex encounters, according to reports citing research from universities in Nanching City.
