The article takes a global focus (which makes sense since most new HIV diagnoses happen outside of the United States), but even the United States has over 30,000 new HIV infections per year.
In 2021 feds mandated that insurance companies must include PrEP as free preventative care, but that doesn't help the most at risk who are young and may not be insured (30-day supply of generic PrEP costs ~$2,500, and every 3 months people must have doctor visit and bloodwork to check HIV and STIs, and for potential liver and kidney damage).
In 2022 a federal judge ruled that they can not require Christian companies to cover PrEP as this violates their religious rights under federal law[1]. This will likely make it's way up to the Supreme Court, and there's a high risk that as a result people in the United States will then need to pay out of pocket for PrEP.
