What is the first stage of tuberculosis?

TB infection happens in 4 stages: the initial macrophage response, the growth stage, the immune control stage, and the lung cavitation stage. These four stages happen over roughly one month.

What are the 3 stages of tuberculosis?

There are 3 stages of TB—exposure, latent, and active disease. A TB skin test or a TB blood test can diagnose the disease. Treatment exactly as recommended is necessary to cure the disease and prevent its spread to other people.

Can chest xray detect TB?

Chest Radiograph

A posterior-anterior chest radiograph is used to detect chest abnormalities. Lesions may appear anywhere in the lungs and may differ in size, shape, density, and cavitation. These abnormalities may suggest TB, but cannot be used to definitively diagnose TB.

Can pneumonia be mistaken for tuberculosis?

It is not uncommon for pulmonary tuberculosis (TB) to be misdiagnosed as pneumonia, particularly in the acute phase when they both present identically. Between five and ten per cent of infected people not receiving treatment for latent TB infection will develop TB during their lives.

What kind of chest pain is associated with TB?

Two other common symptoms of pulmonary tuberculosis are chest pain and shortness of breath. These symptoms may result from pleural effusion (a buildup of fluid between the thin membranes, the pleura, that cover the lungs and line the inside of the chest wall).

There is no need to be worried. Latent TB can be treated before it can cause active TB, and all testing and treatment for TB is free and confidential for everyone.

Is it normal to have latent TB?

In the United States, up to 13 million people may have latent TB infection. Without treatment, on average 1 in 10 people with latent TB infection will get sick with TB disease in the future. The risk is higher for people with HIV, diabetes, or other conditions that affect the immune system.

Can you recover from TB naturally?

You can get TB by breathing in air droplets from a cough or sneeze of an infected person. The resulting lung infection is called primary TB. Most people recover from primary TB infection without further evidence of the disease. The infection may stay inactive (dormant) for years.

What disease is similar to TB?

One of the most common is Mycobacterium avium, which can cause symptoms similar to tuberculosis, such as cough, fever, fatigue, and weight loss.

The latent TB germs are not hurting you and cannot spread to other people. If the TB germs wake up and become active, they can make you sick.

How can you test for TB at home?

Latest fluorescent probe can detect tuberculosis bacteria using a homemade light box and a mobile-phone camera. A highly specific and sensitive fluorescent molecule can rapidly detect tuberculosis (TB) bacteria in sputum samples, according to work published this week in Nature Chemistry¹.

Can a person with TB go to work?

People with TB disease should be excluded from school, day care or the work place until the sputum is negative (about 2-4 weeks after the beginning of treatment). All household and close contacts of a person with active TB disease should be screened using the TB skin test or TB blood test for evidence of infection.
