How long is the duration of tuberculosis infection?

The infectious period of pulmonary tuberculosis is usually about 2-3 weeks, but the specific time needs to be comprehensively judged according to the patient's own situation, severity of illness and other factors. If the patient is in good health and actively cooperates with the doctor's treatment, the infectious period may be shorter.

1. Self-condition: Since each person's constitution is different, the symptoms after infection will be different. For some people with good physical fitness, symptoms of mild cough may occur after infection, and it will also be accompanied by low-grade fever.At this time, the contagion is relatively weak, and generally does not cause much impact on physical health. However, if the immune system is low, there will be obvious uncomfortable symptoms after infection, such as persistent high fever, coughing up a large amount of purulent sputum, etc., and even accompanied by hemoptysis. This condition is relatively contagious and has a relatively long contagion period.

2. Severity of the disease: If the individual's physical resistance is relatively good, and the disease is not particularly serious, the infection period may be shorter after active and effective treatment. However, if the individual's physical resistance is relatively poor, and the disease is more serious, and the treatment is not timely and effective, the infection period may be longer.

It is recommended that patients should take protective measures in their daily lives and avoid sharing daily necessities with others to avoid cross-infection.At the same time, you should also pay attention to rest, maintain adequate sleep, and avoid staying up late for a long time or overexertion. In terms of diet, you can eat protein-rich foods appropriately, such as eggs, milk, etc., which can help strengthen the body's immunity. If you feel unwell during this period, you need to seek medical attention as soon as possible to avoid delaying the condition.
