What are the initial symptoms of tuberculosis?

Tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis, which can invade many organs of the human body, with lung tuberculosis being the most common. Infectious individuals are an important source of infection. Tuberculosis can manifest with various symptoms such as cough, throat congestion, poor appetite, abdominal distension, nausea, and vomiting. What are the symptoms of tuberculosis in its early stages?

Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis infection, which can invade various organs of the human body. In the early stages of tuberculosis, there may be symptoms of toxicity, such as general fatigue, loss of appetite, night sweats, and fever. Typically, low-grade fever occurs from the afternoon to evening, persisting until the morning of the second day before returning to normal. Female patients may also experience menstrual irregularities or amenorrhea due to hormonal disturbances.

Tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis infection. Although the bacteria can invade various organs throughout the body, it primarily affects the lungs, known as pulmonary tuberculosis. Tuberculosis is a chronic and gradual infectious disease that commonly affects young people, with an incubation period of 4 to 8 weeks. Eighty percent of cases occur in the lungs, but secondary infections can also occur in other parts of the body such as the neck lymph nodes, meninges, abdominal cavity, intestines, skin, and bones. Respiratory transmission between individuals is the primary mode of transmission for this disease, with infectious sources being individuals with tuberculosis who expel the bacteria.

With environmental pollution and the spread of HIV/AIDS, the incidence of tuberculosis has become increasingly significant. Clinically, the disease often presents as a chronic process, except for a few cases with acute onset. Common symptoms include low-grade fever, fatigue, and respiratory manifestations such as cough and hemoptysis.

1. History of contact with an infectious individual with tuberculosis.

2. Presence of general symptoms such as low-grade fever and fatigue, as well as respiratory manifestations like cough and hemoptysis.

3. Positive tuberculin test.

4. X-ray examination can detect tuberculosis early and diagnose the location, extent, nature, progression, and treatment outcome of the lesion.
