The school organized a lecture on tuberculosis. In the lecture, we learned a lot about tuberculosis. Tuberculosis is a chronic infectious disease. At first, patients with mild symptoms have no discomfort and generally do not attract attention. Symptoms will only appear when the disease progresses rapidly. Some people have poor resistance, a large number of bacteria infected with tuberculosis are highly toxic, so the symptoms will be very obvious, leading to their general malaise, fever, fatigue, upset, loss of appetite and weight loss after a long time. It can be said that its harmfulness is very great.

The lecture not only introduced tuberculosis, but also told us how to prevent it. The first thing to prevent tuberculosis is to find patients in time. Usually, we should consciously develop good hygiene habits and not spit everywhere; Always open the window in the room to keep the air fresh; Vaccination with BCG to prevent tuberculosis infection; And carry out appropriate physical exercise to enhance personal physique. Only in this way can the incidence of tuberculosis be reduced.

We learned about the spread of tuberculosis and the care of patients. After the lecture, we learned that tuberculosis is spread by Mycobacterium tuberculosis. Mycobacterium tuberculosis can't tolerate damp heat, and it will die at 95℃ 1 min under humid conditions. Therefore, Mycobacterium tuberculosis is cold-resistant, cold-resistant, dry-hot, but not damp-hot. Therefore, the simplest disinfection method for heat-resistant materials used by tuberculosis patients is boiling. Sterilization of books, quilts, etc. It can't be boiled in water, but it can be dried in the sun or disinfected by ultraviolet lamp. Articles touched by patients and articles used by patients can be disinfected with alcohol if they cannot be disinfected by heating or sunlight. Many chemicals, such as carbonic acid, hydrogen peroxide, iodine and alcohol, can kill mycobacterium tuberculosis. So high temperature is the natural enemy of tuberculosis.

After the lecture, I learned about tuberculosis that I had never been exposed to before, and how to prevent tuberculosis, so I won't be afraid blindly in the future. The lecture enriched my knowledge, understood my illness and knew what to do when I met tuberculosis patients in the future. I have benefited a lot.
