Typhoid fever and paratyphoid fever are life-threatening illnesses caused by Salmonella serotype Typhi and Salmonella serotype Paratyphi, respectively. Most people in the United States with typhoid fever or paratyphoid fever become infected while traveling abroad, most often to countries where these diseases are common.
Travelers to Pakistan and other South Asian countries should take precautions. Follow safe food and water guidelines. Vaccinations can help prevent typhoid fever. CDC recommends vaccination for people traveling to places where typhoid fever is common, such as South Asia, especially India, Pakistan, or Bangladesh.
Two typhoid fever vaccines are available in the United States.
Typhoid vaccines lose effectiveness over time. The injectable vaccine requires a booster every 2 years, and the oral vaccine requires a booster every 5 years. If you were vaccinated in the past, ask your doctor if it is time for a booster vaccination. Taking antibiotics will not prevent typhoid fever; they only help treat it.
Visit with a healthcare provider to see if you need a typhoid fever vaccine.
