symptoms of tuberculosis

There are four types of tuberculosis which have different symptoms
  • pulmonary tuberculosis
  • extrapulmonary tuberculosis
  • pleural tuberculosis
  • lymph node tuberculosis 
 Symptoms of pulmonary tuberculosis Pulmonary tuberculosis is the most common manifestation of the disease. The transmission takes place through the air, via aerosols expelled by coughing, sneezing or by the own speech. It is estimated that an infected person, if not treated, can contaminate other 15 in an interval of one year.According to statistics, of these fifteen, only one or two symptoms develop. Attention: only symptomatic cases are capable of transmitting the disease. If you came in contact with the bacillus, but did not develop disease, there is no risk of transmission of bacteria to others.The typical picture of pulmonary tuberculosis is fever with night sweats and chills, chest pain, coughing, at times with streaks of blood, loss of appetite, sluggishness, and weight loss that reaches 10 or 15 kg in a few weeks. Being also a lung infection, the picture may remind us of pneumonia. However, while pneumonia is a more acute disease, which develops in hours / days, tuberculosis is slower, evolving in weeks. Some TB patients seek care only two months after the onset of symptoms. It should always think of pulmonary tuberculosis in patients with pneumonia dragged box that do not improve with antibiotics common.

Symptoms of extrapulmonary tuberculosis TB in other organs often causes weight loss, fever, night sweats , prostration, loss of appetite. The difference is that no respiratory symptoms such as coughing, but specific symptoms of the condition of each organ.
 

Symptoms of pleural tuberculosis extrapulmonary TB is more common pleural tuberculosis, which, as the name says, affects the pleura, the lung lining. The most common symptoms (in addition to those described above) are unilateral chest pain and shortness of breath caused by the appearance of pleural effusion, better known as water in the pleura
.

Symptoms of lymph node tuberculosis Tuberculosis is a common node in the seropositive patients infected with Mycobacterium tuberculosis. The box is typically increased lymph nodes in the neck region.At first, the nodes are slow growing and are painless, then increase in volume and tend to clump together, which can create fistulas (communications) to the skin.

what is tuberculosis?

Tuberculosis is an infectious disease caused by a bacterium called Mycobacterium tuberculosis or Mycobacterium tuberculosis (BK), named after the doctor who discovered it in 1882, Robert Koch.


Koch's bacillus or BK is the bacterium that causes tuberculosis infects the respiratory predilection: pulmonary tuberculosis represents a little more than 70% of TB cases.
The disease can affect all organs. The main locations are described extra-pulmonary lymph nodes, urogenital, musculoskeletal and cerebrospinal meningitis.
This infection is considered a public health priority throughout the world, especially as the number of cases resistant to treatment increases concern.
Depending on the number of drugs that resists BK, is called multidrug resistance (resistance to at least two major antituberculous antibiotics) or highly resistant (resistant to virtually all TB). 
World Day of fight against tuberculosis, held on 24 March each year, is an opportunity to take stock of the situation of the disease in the world and progress in its management.
