United States: good to know

  • PEP in this country. The City of Philadelphia says PEP must be taken within 72 hours of exposure. Call the 24/7 PEP hotline on (833) 933-2815, or go to Health Center 1 (1930 S. Broad St., 2nd floor). The City says the cost of PEP varies by where you get it and may be free depending on your insurance, and that it helps regardless of ability to pay or immigration status. No price is published for people without US insurance.
  • What visitors pay. US care is rarely free for visitors, but the City of Philadelphia says testing and treatment for STIs at its walk-in sexual health clinic (Health Center 1) are free and open to anyone over the age of 13. The page is written for Philadelphians and does not mention short-term visitors.
