TB-prone susceptibility factor

TB-prone susceptibility factors refer to the tuberculosis infection, the incidence and prevalence of susceptibility or trigger factors. These factors will help deepen understanding of the causes of TB incidence and prevalence of understanding. On the clinical management of TB control and prevention will have important significance. 1. Genetic factors: study shows that with the twins after suffering from tuberculosis when its consistency vary much higher proportion of twins, that genetic factors on the TB patients have certainly affected. 2. Age: China's three-tune results showed that the prevalence rate below 20-year-old age rapid growth, moderate growth for the future to 70-year-old reached the peak and then decline again. 3. Gender: 20-year-old former prevalence rate of women than men, then men than women, age sex, have revealed that the TB incidence, prevalence has definitely affected. Postpartum women is especially prone to tuberculosis and blood-derived guitar cerebral tuberculosis, vulnerable to puerperal fever and symptoms of confusion and delay in diagnosis. 40. Occupation: certain occupations and is closely related to tuberculosis. Dust industry such as silicosis, and silicosis are more susceptible to TB. In the long-term care of their end-negative-positive prevalence rate has been higher than 10 times. 5. Tuberculosis and drug: cortex hormones, often hidden immunosuppressant tuberculosis, such as: asthma long-term hormone use, organ transplants and the long-term hormone immunosuppressants, cancer surgery and chemotherapy, which is such . In recent years, more such cases increased. Diabetes, liver and kidney disease, stomach after subtotal, influenza, measles, whooping cough infection, are prone to tuberculosis; malignant lymphocyte immune effects, such as lymphoma, leukemia and AIDS, are susceptible to tuberculosis. Since the mid-1980s, the United States TB prevalence rate of recovery, 1 / 3 attributable to the AIDS pandemic. 6. Malnourished, overworked also susceptible to drop resistance to tuberculosis. 7. Floating population, refugees, immigrants: life due to instability, poor nutrition, fatigue, congestion and easy to live with, the sick. 8. Adverse social environmental factors: such as poverty, war, famine, natural disasters.
