Unlike open tuberculosis
Like many other infectious diseases, tuberculosis is the periods when the likelihood of infecting others a carrier is much higher. A contagious form of tuberculosis is called "open" and means that patients uncontrollably a large amount of microbes that enter the body of another person through contact and is capable of producing infection. The private tuberculosis (BK-) suggests that the patient does not emit into the environment of microbes, and therefore is not contagious.
The risk of infection
For others, the disease is dangerous because it is airborne. Bacteria can easily be transmitted to another person through sneezing, coughing, and normal conversation. Once the bacterium enters another person, it begins to multiply. If a person's immune system is even slightly weakened, to cope with bacteria, the infection will start to develop in the body of its new host and cause the first symptoms of tuberculosis.
In addition to the usual airborne route of transmission, tuberculosis can be transported via airborne dust, contact and food methods. It is worth noting that these types of open transmission of tuberculosis are much rarer. In such cases, the conduits of infection to a sick person serve sputum (when ingested in food or land), personal belongings and household items (toothbrushes, towels, kitchen utensils and even books). Tuberculosis spreads easily through kissing and other contacts (e.g., okurivanie one cigarette).
Varieties and symptoms
Tuberculosis can occur in the lungs and other tissues. According to statistics, most of the patients suffering from pulmonary tuberculosis, but sometimes the infection can cause pathological processes in other organs. For example, there is a tuberculosis of bones and joints, skin, intestines, nervous system, organs of the urogenital system. The disease called when you get an infection in the relevant organ of the human body.
