Diagnosing active tuberculosis based only on signs and symptoms is difficult, as is diagnosing the disease in those who are immunosuppressed. A diagnosis of TB should, however, be considered in those with signs of lung disease or constitutional symptoms lasting longer than two weeks. A chest X-ray and multiple sputum cultures for acid-fast bacilli are typically part of the initial evaluation. Interferon- release assays and tuberculin skin tests are of little use in the developing world. IGRA have similar limitations in those with HIV.
If a patient has some symptoms associated with TB, after what time period should tuberculosis be diagnostically considered?
****
The answer: two weeks

In 1991 a mummy of a neolithic body, known as Otzi the Iceman, was discovered by hikers on the Similaun glacier. His clothing and gear indicate that he lived in an alpine farming community, while the location and manner of his death - an arrowhead was discovered in his shoulder - suggests he was travelling from one place to another. Analysis of the mitochondrial DNA of Otzi, has shown that he belongs to the K1 subclade which cannot be categorized into any of the three modern branches of that subclade. The new subclade has provisionally been named K1o for Otzi.
