Tuberculosis (TB) is a bacterial infection, transmitted through the air, that usually affects the lungs. Symptoms include a long-lasting cough, chest pain, and coughing or spitting up blood. Those at risk for contracting TB are individuals who spend time in close, crowded contact with TB-infected patients. This is especially true when traveling to countries with higher rates of TB. A TB test before leaving the U.S. and 8-10 weeks after returning home can indicate whether you have been exposed to TB.
Typhoid is uncommon in the U.S. However, it is more prevalent in other countries and can be picked up by Americans when traveling. Typhoid fever, caused by the Salmonella typhi bacteria, is spread through food that has been handled by persons infected with this bacterium. It can also be spread through contaminated drinking water. Obtain a vaccination against this disease before traveling to countries where typhoid is more common.
2. Whooping Cough
The whooping cough is distinguished from other respiratory infections by the “whoop” sound an infected individual makes when coughing and drawing in a breath. In the early stages, whooping cough may mimic a cold, with a runny nose, congestion, and a mild cough. As the disease progresses, congestion increases, and it may become difficult to cough up thick, sticky mucus. A person may turn red or blue in the face as they strain to cough up phlegm. Coughing spells may also trigger vomiting, exhaustion, and the telltale whooping sound.
1. Yellow Fever
Yellow fever is transmitted to humans through the bite of an infected mosquito. This disease gets its name from the yellow tint that jaundice gives the skin of yellow fever victims. Other symptoms of this disease are fever, headache, muscle pain, and loss of appetite. Yellow fever is most commonly found in tropical regions of Africa and South America.Related: 10 Diseases That May Show Up on Your Skin
