Access to healthcare, testing, and prevention services

A significant proportion of STIs among sex workers go undiagnosed due to social stigma and limited healthcare access, estimated at 50-70%
The main barriers to STI treatment among sex workers include stigma, criminalization, and lack of access to healthcare facilities, according to multiple studies

Governments in some countries allocate less than 1% of their healthcare budget specifically for STI and reproductive health services targeting sex workers, limiting intervention efforts

Access to healthcare, testing, and prevention services Interpretation

Despite the stark evidence that accessible, stigma-free STI screening cuts infection rates in half, the persistent criminalization and underfunding—less than 1% of healthcare budgets—continue to invisibilize sex workers’ health, fueling a silent epidemic behind societal shame.

Behavioral patterns and condom use practices

In a survey, 78% of sex workers reported inconsistent condom use, increasing STI risk
Condom use among sex workers varies widely from 17% to 85%, impacting STI transmission rates
A report indicates that consistent condom use reduces STI transmission by about 80% among sex workers, underscoring prevention strategies

Impact on health outcomes and co-infections Interpretation

With over half of sex workers battling multiple STIs, a staggering 65% experiencing symptoms annually but only 40% seeking care, and the global economic toll exceeding $10 billion, it's clear that without enhanced screening, destigmatization, and targeted prevention—like PrEP—we're leaving both their health and society vulnerable to a costly, ongoing epidemic.
