Intrapulmonary tuberculosis Tuberculosis is a serious, fatal bacterial infection that most often involves the lungs. There are multiple strains of Mycobacterium divergens that cause TB, the most common of which is Mycobacterium tuberculosis. 1 untreated combined patient infects 10-15 people per year; there are approximately 1 million newly discovered cases of TB in China each year. 1. How is tuberculosis transmitted? It is spread mainly by air. People with active TB infect others by coughing, sneezing, spitting, and speaking, and spewing out the bacterium-carrying droplets. Generally speaking, the closer you are, the greater the risk. 2.How is tuberculosis treated? Tuberculosis itself is curable, but it is not easy to completely remove Mycobacterium tuberculosis and requires strict, at least 6 months of combined adequate antibiotics. 3.How can TB be prevented? Health promotion can reduce transmission, and vaccines can provide appropriate protection, especially for infants. But the most effective prevention is active treatment of active tuberculosis. 4.What are the symptoms of tuberculosis? Coughing up sputum, sometimes with blood; chest pain; weakness. Other atypical symptoms include weight loss, fatigue, low-grade fever, night sweats, etc. Extrapulmonary tuberculosis 1. The tuberculosis bacilli are not only confined to the lungs, but also invade other organs of the body, which is called “extrapulmonary tuberculosis”. 2. Extrapulmonary tuberculosis can be easily confused with other diseases. 3, inhaled tuberculosis bacteria through the blood and lymphatic system to other parts of the body, if the foci of infection in the extra-pulmonary organs, the specific symptoms vary, such as: lumbar spine tuberculosis manifested as back pain; lymphatic tuberculosis manifested as swollen lymph nodes in the neck, armpit or groin; kidney tuberculosis manifested as hematuria. 4. The incidence of extrapulmonary tuberculosis in children is more than twice that of adults. 5. Unlike intrapulmonary tuberculosis, extrapulmonary tuberculosis is often not contagious. 6, extrapulmonary tuberculosis is very easy to misdiagnose, often treated as other diseases for a long time before thinking of tuberculosis. 7.Extrapulmonary tuberculosis occurs in one out of every five patients with tuberculosis.
