What is the difference between primary tuberculosis and secondary tuberculosis?

What is the difference between primary tuberculosis and secondary tuberculosis?

Primary and secondary TB are also thought to have characteristic radiographic and clinical features: primary TB is said to be characterized by lower-lobe disease, adenopathy, and pleural effusions, and termed atypical, whereas secondary, or reactivation, TB is associated with upper lobe disease and cavitation, termed …

What is post primary tuberculosis?

Post-primary (adult type) tuberculosis develops preferentially in people with sufficient immunity to clear and heal caseating granulomas of primary tuberculosis. Post primary tuberculosis is typically restricted to the upper lobes of the lung with no evidence of infection in any other part of the body.

What is the difference between the two strands of tuberculosis?

Tuberculosis (TB) is a highly contagious disease. It’s caused by an infection of bacteria called Mycobacterium tuberculosis (Mtb). Exposure to Mtb can result in either active TB disease or latent TB infection. Latent TB means you’re infected but have no signs or symptoms.

Is TB primary secondary or tertiary?

Tertiary Prevention11 Each person with infectious TB has the potential to infect many others; however, the site of the infection is important in determining its capability to spread. For example, the lungs and larynx are two common organs where TB may be highly infectious.

What is primary progressive tuberculosis?

Progressive primary tuberculosis occurs when the immune response fails to control multiplication of the tubercle bacilli. Infection takes this course in less than 10% of normal adults, but it is common in children under 5 years of age.

What is primary progressive TB?

What are the types of secondary tuberculosis?

Figure 4 : Secondary Progressive Tuberculosis : Advanced cavitary fibrocaseous tuberculosis. Figure 5 : Secondary Progressive Tuberculosis : Tuberculous Bronchopneumonia. Figure 6 : Secondary Progressive Tuberculosis : Milliary Tuberculosis. Figure 7 : Secondary Progressive Tuberculosis : Caseous Pneumonia.

What are primary secondary and tertiary prevention of TB?

Primary prevention and control measures aim to prevent dis- ease before it occurs; secondary measures focus on reducing the impact of the diseases once it has already been established; and tertiary measures aim to de- Page 2 crease the impact of TB and prevent its complications.

What are the types of primary tuberculosis?

Primary Tuberculosis

• Mycobacterium Tuberculosis.
• Lymphadenopathy.
• Lesion.
• Human Immunodeficiency Virus.
• Postprimary Tuberculosis.

What is secondary tuberculosis?

Secondary tuberculosis usually occurs because of reactivation of latent tuberculosis infection. The lesions of secondary tuberculosis are in the lung apices. A smaller proportion of people who develop secondary tuberculosis do so after getting infected a second time (re-infection).

What is secondary TB?

Secondary or Reactivated Tuberculosis. Secondary or Reactivated Tuberculosis. Secondary tuberculosis is usually due to the reactivation of old lesions or gradual progression of primary tuberculosis into chronic form. However, recent evidence suggests that reinfection is responsible for some of the secondary …

What is the most common type of tuberculosis?

This is quite a high number and is rather alarming. The problem with tuberculosis is that it can affect any part of the body. The most common type of tuberculosis that is encountered in India is pulmonary tuberculosis. This is the type that affects the lungs.

What is the difference between primary and secondary drug resistance?

Primary (initial) resistance occurs in persons who have not received any anti-TB therapy and they are initially infected with drug resistant strains. Secondary (acquired) resistance occurs in patients who have previously received anti-TB therapy and resistance develops as a result of inadequate regimen.

Can active TB become latent?

If you breathe in these bacteria, one of three things will happen: your body kills off the TB bacteria so they cannot harm you now or in the future. the TB bacteria make you ill – this is called ‘active TB’ the TB bacteria remain asleep in your body – this is called ‘latent TB’.

What are the different types of tuberculosis?

There are two types of TB conditions: TB disease and latent TB infection. But, if their TB germs become active, they can develop .

What happens in the third stage of tuberculosis?

Stage Three The body brings in more immune cells to stabilize the site, and the infection is under control. At least nine of ten patients infected with Mycobacterium tuberculosis stop at stage 3 and do not develop symptoms or physical signs of active disease.
