A worldwide Internet survey of public knowledge about Tuberculosis.
Pak J Chest Med Jan ;7(Suppl):15-6.

Four simple multiple-choice questions about tuberculosis were posted on a non medical Internet site for a two-month period. A total of 564 responses were received. 62 were excluded as individuals had made multiple attempts at the questions. 65% of responses were from North America, 14.5% from Europe and 12% from Australia and New Zealand with only a small number of responses from Africa, the Indian subcontinent and South America. 49.5% correctly answered that cough is the commonest symptom of TB, 45% knew that TB was transmitted mainly by air-borne droplets, 37.8% knew that TB was caused by a bacterium. Only 19.5% knew that the most important risk factor for developing TB was HIV infection and only 4% answered all questions correctly. This survey suggests that knowledge about tuberculosis is limited in computer literate individuals throughout the world.
