Czech women are not shy about using hormonal and intrauterine birth control. As a result, fewer are using condoms as contraception, which means they’re not protecting themselves from HIV, Czech News reports. According to a survey conducted by the Institute of Health and Statistics, 70 percent of women in capital city Prague and neighboring regions use hormonal or intrauterine contraception.

In July, 21 people in the country tested positive; eight were from Prague. In the Vysocina and Pardubice regions, 47 percent of women use hormonal contraception; no HIV cases were reported in those regions.

Dům světla (House of Light) provides support to the HIV-positive people and gives free tests. Dům světla director, Miroslav Hlavaty, says that at least a quarter of HIV-positive people are unaware of their infection and keep spreading it.
