What causes tuberculosis
In recent years, tuberculosis (TB) has once again become a public health issue of global concern. Despite advances in medical technology, tuberculosis remains endemic in many regions, especially in developing countries. This article will discuss the causes, transmission routes, symptoms and preventive measures of tuberculosis, and provide you with a comprehensive analysis based on hot topics and hot content in the past 10 days.
1. Causes of tuberculosis
Tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis. This bacterium is mainly spread through the air. When an infected person coughs, sneezes or talks, they release bacteria-carrying droplets into the air, which others may inhale and become infected. The following are the main causes of tuberculosis:
| Cause | Description |
|---|---|
| Mycobacterium tuberculosis infection | The direct pathogen of tuberculosis is mainly transmitted through the respiratory tract. |
| low immunity | People with AIDS, diabetes, or those taking immunosuppressants for a long time are susceptible to infection. |
| Poor living environment | Crowded, poorly ventilated environments increase the risk of transmission. |
| Malnutrition | Lack of nutrients weakens the immune system and increases the chance of infection. |
2. Symptoms of tuberculosis
Symptoms of TB vary depending on the site of infection, but the most common TB symptoms include:
| Symptoms | Description |
|---|---|
| persistent cough | A cough that lasts for more than two weeks may be accompanied by bloody sputum. |
| low fever | Low fever occurs in the afternoon or evening, and the body temperature is usually around 37.5°C. |
| Night sweats | Sweating profusely at night while sleeping. |
| weight loss | Unexplained weight loss. |
| Weakness | Continuous feelings of tiredness and lack of energy. |
3. Prevention and treatment of tuberculosis
The key to preventing tuberculosis is to cut off transmission routes and improve immunity. Here are some effective preventive measures:
| Precautions | Specific methods |
|---|---|
| Vaccination with BCG vaccine | BCG vaccination in infants and young children can prevent severe tuberculosis. |
| Improve living environment | Keep indoors well ventilated and avoid crowding. |
| Enhance immunity | Have a balanced diet, regular work and rest, and moderate exercise. |
| Early diagnosis and treatment | Seek medical attention promptly when suspected symptoms appear to avoid delays in treatment. |
4. The relationship between hot topics in the past 10 days and tuberculosis
Recently, an increase in tuberculosis cases has been reported in many places around the world, especially in countries such as India and South Africa. The following is the hot content related to tuberculosis in the past 10 days:
| hot topics | Content summary |
|---|---|
| Tuberculosis epidemic in India | The Indian government has announced that it will strengthen tuberculosis screening and treatment with the goal of eliminating tuberculosis by 2030. |
| Co-infection of COVID-19 and tuberculosis | Studies have found that the incidence of tuberculosis has increased among people who have recovered from COVID-19, which may be related to reduced immunity. |
| New tuberculosis vaccine development | Scientists are testing a new tuberculosis vaccine that is expected to be available within the next few years. |
| Tuberculosis drug resistance | The increase in drug-resistant tuberculosis cases poses challenges to global prevention and control. |
5. Conclusion
Tuberculosis is a preventable and curable disease, but it requires the joint efforts of the whole society. Through early diagnosis, standardized treatment and effective prevention, we can reduce the spread and harm of tuberculosis. If you or someone around you develops suspected symptoms, please seek medical treatment promptly to avoid delaying the condition.
