Checking insurance quotes…
Before You Go
Make sure your health-insurance policy covers travel to California. If it does not, consider a travel-insurance policy that covers emergency medical services.
No specific vaccinations are required for travel to the US, though it is always sensible to ensure that your routine vaccinations are up to date.
In San Francisco
The city's tap water is not only drinkable but of excellent quality: it's straight from Hetch Hetchy Reservoir in the High Sierra mountains of Yosemite National Park.
Before traveling, contact your health-insurance provider to learn what medical care they will cover outside your hometown (or home country). Overseas visitors should acquire travel insurance that covers medical situations in the US, where nonemergency care for uninsured patients can be very expensive.
For nonemergency appointments at hospitals, you'll need proof of insurance, or credit card or cash. Even with insurance, you'll most likely have to pay up front for nonemergency care and then wrangle afterward with your insurance company to get reimbursed. San Francisco has excellent medical facilities, plus alternative medical practices and herbal apothecaries.
