What is active TB case finding?
Active case-finding (ACF) or systematic screening for tuberculosis is an important tool to reach out to missing TB patients. When appropriately implemented, the activity is cost effective, helps to reduce diagnosis and treatment delays, and prevents the spread of the disease.
How many active TB cases are there?
TB is a leading cause of death among people with HIV, especially in developing countries. In 2019, an estimated 815,000 of the approximately 10.0 million new active TB cases affected people who were also HIV-positive, and of the 1.4 million people who died from TB, an estimated 208,000 were HIV-positive.
What is active and passive case finding?
Passive case finding is standard and consistent with the WHO-recommended Stop TB Strategy 2. Active case finding includes all methods for the identification and then treatment of those with TB who have not reported to the healthcare system of their own accord.
What is the most accurate diagnostic test for active tuberculosis?
The most commonly used diagnostic tool for tuberculosis is a skin test, though blood tests are becoming more commonplace. A small amount of a substance called tuberculin is injected just below the skin on the inside of your forearm. You should feel only a slight needle prick.
What is a case finding?
Casefinding is a system for locating every patient, either inpatient or outpatient, who is diagnosed and/or treated with a reportable diagnosis. All healthcare facilities must perform case finding.
What is passive case finding in TB?
It is the number of persons screened divided by the number of persons diagnosed with TB (roughly the inverse of the prevalence). Passive TB case-finding is a person-initiated pathway to TB diagnosis involving the.
Is tuberculosis active or passive surveillance?
53 (23%) of 232 contacts with tuberculosis were diagnosed through active case-finding and 179 (77%) were identified through passive case-finding. During the first 6 months of the study, 23 (45%) of 51 contacts were diagnosed through active case-finding and 28 (55%) were identified through passive case-finding.
What is passive case finding TB?
People with TB are often diagnosed through passive case finding (PCF) when they present to clinics (primary health care centers) with TB symptoms. ACF is generally considered to be any other method of reaching people with TB outside of the primary health care system.
Does XRAY confirm TB?
Therefore chest x-rays are usually an indicator of whether or not a person might have TB, but they cannot confirm the diagnosis. They are used to confirm a suspicion, and will always be followed by tests that aim at finding the TB bacterium. The diagnosis of TB cannot be made by a chest x-ray alone.
What is the difference between active and inactive TB?
People with latent TB do not have any symptoms and cannot spread TB. If they do not get treatment, however, they may develop active TB disease in the future, spread the disease to others, and feel quite ill. People with active TB disease can be treated and cured if they get medical help.
What is case finding in medicine?
What is screening and diagnosis?

Fever, night sweats, anorexia, nonproductive cough, failure to thrive, and difficulty gaining weight may occur. Signs of disease depend on the site involved (pulmonary or extrapulmonary).
What is the difference between latent and active tuberculosis?
What is intensified case finding?
Intensified case finding (ICF) is an activity intended to detect possible TB cases among people living with HIV as early as possible. TB is under-diagnosed in people with HIV, and a major cause of death.
