Overview
TB is transmitted through airborne particles when an infected person coughs or sneezes. While it mainly impacts the lungs, TB can also affect other organs. Symptoms include a persistent cough, chest pain, and weight loss. The BCG vaccine is administered to individuals at higher risk, particularly in areas where TB is prevalent.
Risk Areas
TB is widespread globally, with higher prevalence in regions such as Africa, parts of Asia, and Latin America. Travelers to these areas should be aware of the increased risk. According to the Centers for Disease Control and Prevention (CDC), individuals born in or frequently traveling to countries where TB is common, including some countries in Asia, Africa, and Latin America, have a higher chance of being infected with TB germs.
Risk for Travelers
Travelers to high TB prevalence areas are at increased risk, especially if they have prolonged exposure in crowded places, healthcare facilities, or consume unpasteurized dairy products. It's essential to be aware of TB symptoms and seek medical attention if they develop during or after travel.
