The early flags for TB, as listed in the Series of National Guidelines for TB 5 are: By having a high level of vigilance for TB, appropriate isolation can occur at an early stage. The most effective measure to control TB in a healthcare setting is early detection. Top of page Importance of early detection It is not transmitted by touching surfaces such as bed linen, toilet seats, shaking hands etc. tuberculosis is transmitted only through air containing microdroplets of TB organisms.

aerosol generating procedures) and host vulnerability must all be taken into account. Intensity of smear positivity, mechanical factors (e.g. In healthcare settings, the duration is often considered significant after eight accumulative hours of exposure have occurred but this is not an absolute cut off for decision making. Household members are at greatest risk of acquiring TB from an index case of pulmonary tuberculosis. The risk of transmission increases with duration of exposure. Infectivity is directly related to the magnitude of viable organism load in respiratory secretions. 4 Depending on the environment, tubercle bacilli can remain suspended in the air for prolonged periods and air currents can carry them throughout a room or building. tuberculosis is generated and carried in droplet nuclei particles that are approximately 1–5 μm in size. When a person with pulmonary TB coughs, sings, laughs or sneezes, M. TB is spread via inhalation of small particle aerosols (airborne route). These guidelines provide recommendations for healthcare workers to manage patients who are confirmed or suspected of having pulmonary TB.

The risk of transmission in healthcare settings is increased when healthcare workers and patients come in contact with persons who: 3 Laryngeal tuberculosis should be considered as having the same or greater risk of transmission as smear positive pulmonary tuberculosis.

Persons with extrapulmonary disease are usually not infectious unless the TB disease is located in the larynx or the oral cavity or if the extrapulmonary disease includes an open abscess or lesion where drainage fluid may be aerosolised. 1 TB disease can occur in pulmonary and extrapulmonary sites. 2 Worldwide, TB incidence is slowly declining and it is estimated that 43 million lives have been saved between 20. 1 In Australia, there are around 1,200 to 1,400 cases of TB each year.

tuberculosis is responsible for an estimated 9.6 million new tuberculosis (TB) cases per annum with 1.5 million deaths estimated in 2014. Tuberculosis is caused by the bacterium Mycobacterium tuberculosis.
