Is lymph node TB transmissible

Disseminated tuberculosis

What is disseminated tuberculosis?

Tuberculosis is a contagious disease caused by the bacterium Mycobacterium tuberculosis. When the disease spreads from the lungs and affects other organs, it is known as disseminated (widespread) tuberculosis.

The symptoms depend on which organ system is affected by the disease. However, they often include fever, chills, night sweats, unwanted weight loss, and fatigue. Diagnosis is based on taking a small sample (biopsy) of the infected organ to detect the infection.

Treatment for disseminated tuberculosis usually involves taking a combination of different antibiotics for six to twelve months. Most people recover well, although it will take some time for symptoms to improve.


Tuberculosis is an infection caused by the bacterium Mycobacterium tuberculosis. This is very contagious and is transmitted through the air and droplets from the mouth and throat of an infected person.

Tuberculosis usually affects the lungs, but it can also spread through the body through the bloodstream, affecting other organs, known as disseminated (widespread) tuberculosis. The spine, intestines, and kidneys are often affected.

People who live in areas that do not have good access to health care, are not well fed and who live in cramped conditions are at higher risk of developing tuberculosis. This also affects people with a weakened immune system, especially if they have HIV, as well as children and the elderly.


The symptoms depend on which organ systems are infected with the bacterium. Common general symptoms of tuberculosis are:

  • Fever and chills,
  • night sweats,
  • Malaise,
  • Joint pain,
  • Weight loss,
  • Fatigue,
  • pale skin,
  • swollen lymph nodes,
  • Cough and shortness of breath.

Other symptoms may include bone pain, diarrhea, abdominal pain, and swelling or blood in the urine.

If you are unsure whether these symptoms apply to you, start a symptom analysis.


Diagnosing disseminated (widespread) tuberculosis can be difficult. Even if a person who is at risk of developing tuberculosis is suspected of having the diagnosis based on the symptoms occurring, a Tuberculosis infection can only be proven through research.

Mostly will be several tests needed. These may include x-rays or other imaging tests to look for tuberculosis infections in the lungs or other organs. A skin or blood test can also be used to prove previous exposure to the bacteria. In some cases, a small sample (biopsy) of the infected organ can also be taken and examined for the presence of bacteria.


Disseminated tuberculosis is made with the same combination Antibiotics treated as well as tuberculosis in the lungs, but the antibiotics usually have to be taken for a long time. It can take anywhere from six to twelve months to fully treat the infection.


In most cases, those with tuberculosis respond well to antibiotic therapy. However, it can take several weeks or months for symptoms to improve.


People traveling to areas where tuberculosis is present can get vaccinated beforehand or get tested for tuberculosis infection when they return. Individuals who have a tuberculosis infection should be given a full cycle of antibiotic treatment to effect complete recovery.
