![]() An estimated 10.4 million new infections were noted in 2015. In 2014, the global incidence of latent tuberculosis infection (LTBI) calculated via mathematical modeling was 23%. Īs patients with LTBI do not exhibit any symptoms, LTBI incidence has to be estimated. The global mortality of tuberculosis infection was estimated at 1.4 billion by the World Health Organization and 1.3 billion by the Global Burden of Disease study in 2013. Therefore, those with LTBI are at risk for developing active tuberculosis and infecting others while risking personal morbidity and mortality. Lifetime reactivation risk is estimated at 5% to 10% and increases with immunosuppression. These patients have the highest reactivation risk within the first two to five years of initial infection, during which LTBI can progress to active tuberculosis. Most are noted with latent tuberculosis infection (LTBI) characterized by M tuberculosis in a dormant state with no evidence of any symptoms. After initial infection, patients can progress to active tuberculosis or eliminate the organism via the innate immune response or T-cell immunity. Clinical disease, termed active tuberculosis, is most frequently characterized by pulmonary disease, but extrapulmonary manifestations can also be observed. Source: caused by Mycobacterium tuberculosis, is an infection that occurs on a spectrum between latent and clinical disease. Always seek the advice of your physician or other qualified health provider with any questions you may have regarding a medical condition. ![]() ![]() The contents herein are for informational purposes only. This test may be used in combination with other tests, such as chest X-rays (which can show whether a person has an active TB infection), to detect TB.Īntibiotics are the standard treatment for TB and they provide a safe, effective cure for this condition.Īll material copyright MediResource Inc. In cases where a person has symptoms of tuberculosis, your doctor will consider the test result and determine the appropriate treatment. Keep in mind that no test is 100% accurate, and as with any test, this test may produce false positive results (a positive result for someone who does not have the condition) or false negative results (a negative result for someone who really does have the condition). The skin may be red or show no colour change. The result is negative if there is either no bump or if the bump is smaller than a certain size (see above). This means that, at some point in your life, you have been infected by the bacteria that cause TB. The result is positive if there is a firm bump larger than a certain size (the size depends on your medical history and risk factors).
