Against tuberculosis

Spring is the season of high incidence of TB, in the end what is tuberculosis, they should how to prevent it?
What is tuberculosis?
Tuberculosis commonly known as "TB", is a chronic respiratory disease caused by M. tuberculosis. Mycobacterium tuberculosis can invade various organs of human body, but it mainly affects the lungs, called pulmonary tuberculosis. What organs TB violations What organs tuberculosis, such as violations of meninges called meningeal tuberculosis, violations of bone called bone tuberculosis. TB accounts for more than 80% of all types of tuberculosis, and tuberculosis is the main type of TB infection.
The main symptoms of tuberculosis is continuous cough, expectoration more than 2 weeks, or sputum with bloodshot eyes. At the same time, it may be accompanied by chest pain, night sweats, afternoon fever, general fatigue, loss of appetite and other common symptoms.
Tuberculosis can be cured?
Just adhere to regular treatment, the vast majority of TB patients can be cured. Emerging infectious tuberculosis medication is generally required to completely cure time of 6 to 8 months, and the middle and can not miss a dose intermittent medication. If unauthorized withdrawal or intermittent medication, not only easy to relapse, there may be resistance. Resistant tuberculosis patients after treatment technology complex, longer treatment time (18 to 24 months), treatment costs more (about 100 times the non-drug-resistant TB treatment costs around).
"We must take medicine under the supervision of a doctor and his family," deputy director of the Chinese Center for Disease Control Center Chenming Ting knot to remind you that one month of treatment in general, symptoms will be significantly improved, patients are often mistaken for the disease has been cured and self-withdrawal causing TB has been suppressed and repopulate resistance.
How to prevent tuberculosis?
Cover: consciously choose to wear a surgical mask, according to Beijing Chest Hospital central sterile supply for 20 hospitals in 32 tuberculosis area of ​​disinfection and isolation Survey found that: nearly forty percent of patients with pulmonary tuberculosis ward rarely wear masks, are only a small part Liucheng Ward patients wear masks. TB patients with a reasonable standard to wear surgical masks (sub-absorbent layer, a filter layer and a water-repellent layer, bacterial filtration efficiency of greater than 95%, non-oily particles on filtration efficiency of greater than 30%), not only can reduce the spread of TB in the air to ward , and also avoid the risk of other pathogens in the patient's own infection.

Place: was empty window ventilation masks alone intercept bacteria and viruses is not enough ventilation window can not be ignored. I must say it is a ward ventilation can remove 63.2% of the original number of bacteria. Ideally ventilation frequency of 12 times / h or more (when the outgoing and the incoming ventilation air is reached once the room volume). In a poorly ventilated room, natural ventilation should be installed auxiliary equipment.
Sweep: the upper space of traditional ultraviolet irradiation ultraviolet radiation generates ozone has harmful effects on the human body, so the ordinary downward irradiating ultraviolet light can only be used in the absence of state; and UV air disinfection cycle of wind, although in the case under someone open, but high for the room airtight requirements. We recommend using the upper space ultraviolet irradiation sterilization technology, install baffles or blinds passes under the UV light to ward upper space through the upper and lower air circulation to achieve the purpose of continuous disinfection, sterilization can also continue in the case of someone.
