Recently, I was interviewed by Tencent Health about tuberculosis, and the main content is as follows: 1. Director Tang: According to records, the tuberculosis bacillus was found in a 4,500-year-old mummy in Egypt, and in our country, it was also found in the female corpse of Mawangdui in Hunan Province 2,100 years ago. Recent molecular biology studies have shown that tuberculosis can be up to 10,000 years old. In 1882, the famous German scientist Koch first discovered the tubercle bacillus, and since then, tuberculosis has entered a new era. 2.When it comes to tuberculosis, the first reaction is whether it is contagious? Director Tang: Yes, tuberculosis is actually a chronic, infectious disease, because more than 95% of tuberculosis is pulmonary tuberculosis, in tuberculosis, it is estimated that about 30-50% is infectious, so some of the infectious mainly in the sputum of patients found in the tuberculosis bacilli, including smears found in the tuberculosis bacilli, called smear positive, and in the culture fluid found in the tuberculosis bacilli, called culture fluid In some patients with tuberculosis who are not found to have TB bacilli, there are still some patients who are infectious, but our modern means have not yet detected it, and it is a bacillus detoxification. 3. Do we have any physical protection measures, for example, to prevent ourselves from getting TB? Director Tang: There are some physical protective measures, including exercising, but you have to master the spring, summer, autumn and winter exercise, because in the spring, it is usually better at seven or eight o’clock in the morning or four or five o’clock in the afternoon. In the summer, you try to go out in the early morning hours, when the sun is not out to exercise. In the fall, generally speaking, basically morning and evening can be. In winter we have to be careful, now the haze is more, when the haze, we try not to go outdoors, then if you go outdoors, to wear a mask, because the mask is to prevent haze, but also to prevent the inhalation of tuberculosis bacteria. 4, about the spread of tuberculosis, especially the spread of tuberculosis, the Internet is also abuzz, saying that they are particularly evil, so we are here, officially, authoritatively talk to you, which are the several ways of transmission of tuberculosis? Director Tang: The main way of transmission of tuberculosis is actually respiratory transmission, respiratory transmission is sometimes, to be honest, the main thing is not very hygienic, he spit, and sometimes sneeze, cough, speak, this time, we recommend that some infectious tuberculosis patients like this, it is best for them to wear a mask, if you go to where, after all, we can not restrict your freedom, you want to go to public places Buy something, go to the mall, you better consciously wear a mask. 5. Recently, I heard a term, which is newly hot on the Internet, that there is a kind of tuberculosis called multi-drug-resistant tuberculosis, right? Director Tang: Yes, this is called drug-resistant tuberculosis or drug-resistant tuberculosis, because the development of new drugs lags behind, tuberculosis is not taken seriously, including the concept of the general public are now saying that tuberculosis has long been gone, our prevention and treatment measures are not in place, and some patients do not regulate their own medication, eat a period of time he stopped for a period of time, after stopping and bad, he came back to the doctor to prescribe drugs, drugs prescribed after After the drug is prescribed, his symptoms are better and he stops taking the drug, which is the most likely cause of drug-resistant tuberculosis. Therefore, in the last decade or so, the trend of drug-resistant tuberculosis is increasing globally, including in our country.
