But this is not the case. Each of us should be careful of tuberculosis.
Health headlines (micro-signal: baojiandaifu) first explain why everyone should be careful.
Someone around you must be infected with tuberculosis.
The chief culprit of tuberculosis is tuberculosis infection. About one third of the people in the world are infected with tuberculosis, and domestic surveys show that about 20-40% of them are infected. In other words, we or people around us must be infected with tuberculosis.
Some people here may wonder, "There are so many infected people, but no one around us has tuberculosis." 」。
Admittedly, "infected with tuberculosis" does not mean "infected with tuberculosis", because among people infected with tuberculosis, the probability of developing tuberculosis in their lifetime is 10%.
Infection with tuberculosis is not necessarily a disease, but tuberculosis in the body is like an untimely bomb. When our resistance drops, it may lead to tuberculosis, cough, expectoration, fever, weight loss and other symptoms.
Tuberculosis is not a "special disease" for the poor.
Many people around us are infected with tuberculosis, but most of them will not develop tuberculosis, and personal immunity plays a key role in it.
Poor people, due to malnutrition, poor living conditions and other reasons, may lead to low immunity and eventually suffer from tuberculosis.
But tuberculosis is not a disease of the poor. The following people are also prone to tuberculosis:
1. Elderly people
After entering the old age, the functions of various organs of the human body gradually decline, and the immunity also declines. Once the immunity drops, newly infected or latent Mycobacterium tuberculosis will easily make waves and lead to tuberculosis.
2. Diabetic patients
The prevalence of pulmonary tuberculosis in diabetic patients is 2~4 times higher than that in non-diabetic patients, and the prevalence of pulmonary tuberculosis in patients with poor blood sugar control is 3 times higher than that in patients with good blood sugar control. Because when blood sugar control is not ideal, the immune function of the body is suppressed and it is more likely to be infected with tuberculosis.
3. Infants and children
Infants and young children are not fully developed, their immunity is not perfect, and they are more likely to come into contact with tuberculosis from their families. After the baby is infected, the condition is often more serious and even fatal tuberculosis, such as tuberculous meningitis, appears.
4. Migrant workers
In China, the floating population is mostly young and middle-aged. After entering the city, most of them have poor living environment, hard work, poor nutritional conditions and great mental stress, which leads to the decline of physical resistance. Therefore, they are also high-risk groups of tuberculosis.
5. People with AIDS
The immune system of AIDS-infected people will be destroyed, and they will be more susceptible to tuberculosis.
Prevent tuberculosis from three aspects.
1. Reduce TB exposure
Tuberculosis is everywhere, but the amount of exposure to it will also affect whether it is infected or sick, so reducing exposure is helpful to prevent diseases.
For example, wearing a mask when visiting tuberculosis patients; Tuberculosis patients at home should live in a separate room, and clothes, tableware and sputum should be disinfected. The elderly and children should avoid contact with tuberculosis patients as much as possible.
The most important thing is to enhance your immunity.
Tuberculosis is hard to prevent, so it is particularly important to enhance your own immunity.
Maintain a healthy lifestyle, do not smoke or drink;
Eat a balanced diet, not partial eclipse, not picky eaters, and provide enough nutrition for the body;
Friends with diabetes should actively control blood sugar, and friends with other chronic diseases should actively control the primary disease;
For newborns at home, BCG should be vaccinated in time under the guidance of doctors; Although BCG can not completely eliminate tuberculosis infection, it can reduce the incidence of tuberculosis. Even if infection occurs, the condition is mild.
3. If you suspect tuberculosis, you should seek medical advice in time.
When you have cough and expectoration for more than 2 weeks, accompanied by low fever, fatigue and other symptoms, you must go to the hospital for tuberculosis screening, early detection and early treatment.
