A person can be a carrier of the pathogen for yearstuberculosis and not suspect an infection. In some cases, the symptoms of the disease manifest like a common cold. Therefore, in the early stages it is not easy to identify the presence of a disease. In this material, we will try to find out how TB is defined, which methods of treatment should be used to solve the problem.
Bacteria of tuberculosis are most often transmitted fromthe carrier of the disease to a healthy person by airborne droplets, which leads to the settling of the causative agent of tuberculosis in the lungs. Infection can also occur through household contact with bacteria, if they get into the digestive tract directly.
The probability of infectious defeat with Koch chopsticks is only 5% for a healthy person with good immunity. People with a weakened body are more likely to be infected.
Risk groups are young children and adolescents. Women under 35 are more likely to become infected with a tuberculosis pathogen compared to young men.
Among the risk factors is:
How to identify tuberculosis at an early stage?If you find the above symptoms, you should contact the hospital for taking a smear. The composition of the obtained sample is studied under a microscope under laboratory conditions.
It is worth noting that negative resultsthe test is not always said about the absence of ailment. Quite often, the development of the disease at an early stage does not allow us to detect microscopic bacteria in the smear of sputum from the lungs. It is for this reason, in the presence of obvious symptoms of tuberculosis, it is important to repeat the research after a certain time.
The diagnostic method involves samplingsputum with the subsequent cultivation of a culture of bacteria in the laboratory. How is tuberculosis determined in this way? Such an analysis may take several months, because during the tests, experts check the sensitivity of microorganisms in the crop to the effects of various antibiotics. However, carrying out the research allows identifying the causative agent of the disease with high accuracy.
Sputum culture also acts in a good wayTo determine the stability of a particular variety of Koch's bacillus to the effects of certain medications. At the moment there are no alternative research methods that would allow to obtain the specified information.
How is tuberculosis of extrapulmonary form determined? The first signs of the development of this disease are:
How to identify a child with tuberculosis?For this. In addition to hyperergic injection tests, fluorography methods have been used since the age of 15 years. If there are obvious symptoms of the disease, sputum culture is carried out.
The initial stage of tuberculosis development is not easynature of the course of the disease. Manifestations of the disease can easily be confused with the symptoms of a common cold or flu. To avoid defeat of the body by the causative agent of tuberculosis, do not forget about the factors that can lead to infection. Periodically, it is necessary to resort to diagnostic procedures in the prevention plan.
