How can I tell if I have tuberculosis or a cold, and what do you need to know about tuberculosis?

If you have a cold, it will only be a lack of breath through your nose, or a runny nose and sneezing, and if you have a severe cough and chest tightness, and a low-grade fever, it may be tuberculosis.

Tuberculosis is usually characterized by low-grade fever in the afternoon, cough with sputum, and even hemoptysis. People with tuberculosis usually feel weak and lose weight in a short period of time, which is different from a cold.

If you have tuberculosis, you will have a cough, a sore throat, and inflammation in the lungs, so it can be seen completely, and there is still a certain difference from the common cold, so it is recommended to go to the hospital for examination in time, which is the most important thing.

Tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis infection, and the bacteria in this infectious disease will invade all organs of the body, but the main organ is the lungs, also known as tuberculosis. Tuberculosis is generally more common in young people, it is divided into chronic and slow-onset, and the incubation period is generally 4 to 8 weeks. The main site is in the lungs, but other parts such as lymph, meninges, peritoneum, **, bones, etc. can also be infected one after another.

Common symptoms include low-grade fever, fatigue, cough, and coughing up blood.

Tuberculosis is a chronic infectious disease that young people are prone to, which is caused by conjugate bacillus infection, which may invade various organs of the human body, but the most important thing is to invade the lungs of the human body, which is often referred to as pulmonary tuberculosis.

The incubation period for tuberculosis is usually 4 to 8 weeks, and it is usually transmitted through the respiratory tract from person to person, and the source of infection is contact with a tuberculosis patient who has shed the bacterium.

Patients with pulmonary tuberculosis are usually asymptomatic or mild in the early stages and are easily ignored, but if the lesion is active, the body temperature rises in the afternoon, usually a low-grade level.

It is generally about 37 to 38 degrees, and patients are often accompanied by general fatigue, weight loss, and night sweats; Women may also experience menstrual irregularities or menopause. In addition, the most important symptoms of early tuberculosis are cough, sputum production, and blood streaks or small blood clots in the sputum.

Tuberculosis is a chronic infectious disease caused by infection with the bacterium Mycobacterium tuberculosis. The bacteria in this infectious disease invade various parts of the body. organs, but the main organ affected is the lungs, also known as tuberculosis.

Tuberculosis usually occurs in young people. It is divided into chronic and late-onset. The incubation period is generally 4 to 8 weeks.

It is a lung disease, and I have tuberculosis because of the infection that causes coughing all the time, and I learned that the incubation period of this disease is very long.

Typical tuberculosis has a mild-onset and prolonged course with low-grade fever, fatigue, loss of appetite, cough, and a small amount of hemoptysis. However, most patients have mild lesions, often no obvious symptoms, and are only found on X-ray health examination; Some patients are detected with sudden hemoptysis, but mild symptoms of toxicity can be traced over the course of the disease.

Tests must be done to confirm the diagnosis, and what tests are needed for tuberculosis.

As follows: 1. Tuberculosis examination:

The presence of tuberculosis bacteria in sputum is the main basis for the diagnosis of pulmonary tuberculosis. A positive sputum is indicative of an open lesion. The amount of sputum bacteria is small, and the bacteria collection method can be used. The culture method is more accurate, in addition to understanding whether tuberculosis bacteria have the ability to grow and reproduce, and can also be used for drug susceptibility testing and microbial type identification.

2. Imaging examination:

Chest X-ray examination can not only detect pulmonary tuberculosis early, but also make judgments on the location, scope, nature, development and effect of the lesion, which is very helpful for deciding the best plan. Chest CT is helpful in detecting small or occult lesions and understanding the extent and composition of lesions.

3. Tuberculin (referred to as tuberculin) test:

OT test: less than 5mm is negative, 5 9mm is weakly positive, 10 19mm is positive, and more than 20mm or local blisters and necrosis are strong positive.

PPD test: used for clinical diagnosis, the average diameter of induration is 5 mm as a positive reaction.

4. Other examinations:

The erythrocyte sedimentation rate (ESR) of active tuberculosis may be increased but is not specific for diagnosis, and a normal erythrocyte sedimentation rate does not rule out active tuberculosis.
