Tuberculosis is a common, globally significant and deadly infectious bacterial disease. Tuberculosis generally affects the lungs, but it can also affect other organs. The symptoms of pulmonary tuberculosis are sputum and a cough that can last for as long as several months. The majority of those infected remain asymptomatic through their entire lives, but symptoms can appear decades after infection due to reduced immune function caused by aging, for example. While tuberculosis is mainly a problem in third-world countries, the disease is also found in Russia and the Baltic countries. The vaccine is included for risk groups in the National Vaccination Programme.
