March 24 is the 26th World Tuberculosis Day. Tuberculosis is mainly transmitted through the respiratory tract. Experts pointed out that schools and students are the key places and important groups for tuberculosis prevention and control.
Sun Dingyong, director of the Tuberculosis Prevention and Control Institute of the Henan Provincial Center for Disease Control and Prevention, said that tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis infection. It mainly invades the lungs and causes pulmonary tuberculosis. The symptoms are mainly cough, expectoration of sputum for more than 2 weeks, as well as fever, night sweats, and fatigue. The route of transmission is that the droplets expelled by excreted tuberculosis patients through loud talking, coughing or sneezing are inhaled by people around them, thereby becoming infected.
Tuberculosis is very likely to cause a clustered epidemic in crowded places, such as schools, nursing homes, etc., once the source of infection exists for a long time. Schools are places with a high concentration of crowds. Students have close contact in school learning and living activities for a long time, especially students in boarding schools. Therefore, tuberculosis prevention and control in schools is a top priority.
Sun Dingyong suggested that, first of all, school leaders, teachers and students need to have a basic understanding of tuberculosis-related knowledge, master the suspicious symptoms and transmission routes of tuberculosis, and enhance self-protection awareness. Secondly, indoor places such as school classrooms and dormitories should be ventilated, strengthen air circulation, and disinfect the air (ultraviolet rays) to reduce the risk of tuberculosis infection. Finally, students should strengthen exercise, improve their immunity, and maintain good work and rest habits. At the same time, it is necessary to maintain a healthy mentality and not have excessive anxiety about tuberculosis infection.
