Background: Female sex workers (FSWs) play a critical role in the heterosexual transmission of human immunodeficiency virus (HIV)/sexually transmitted infections (STIs) in China. Several studies reported that street-based FSWs have higher risk behaviors than establishment-based FSWs. Therefore. street-based FSWs should be specifically targeted for HIV and STIs intervention programs. https://fitnessgravesyardes.shop/product-category/overlay-grip-switch/
