Legionnaires' disease is now routinely discussed as an 'emerging infectious disease' (EID) and is said to be one of the earliest such diseases to be recognised. It first appeared in 1976 and its cause was identified in 1977, the same year that Ebola fever, Hantaan virus and Campylobacter jejuni arrived. The designation of Legionnaires' disease as an EID was retrospective; it was not and could n...

Edi tor ’s Note : NEHA strives to provide up-to-date and relevant information on environmental health and to build partnerships in the profession. In pursuit of these goals, we feature a column from the Environmental Health Services Branch (EHSB) of the Centers for Disease Control and Prevention (CDC) in every issue of the Journal. In these columns, EHSB and guest authors share insights and inf...

Many respiratory diseases are caused by extracellular bacterial pathogens; however, two very important lung infections are due to intracellular pathogens, Legionnaires' disease and tuberculosis. Legionnaires' disease remains problematic due to our inability to predict where sporadic epidemics will occur and the speed at which the bacterium debilitates its victims. The development of better meth...

Campylobacter enteritis, giardiasis, legionnaires' disease, primary amoebic meningoencephalitis, and the viral haemorrhagic fevers are among the "new" diseases. In hospitals group B streptococcal infections have been recognised, there have been episodes of hospital-acquired enterovirus infections, and developments in surgical prostheses and immunosuppression have been followed by the appearance...

BACKGROUND Legionnaires' disease cannot be clinically or radiographically distinguished from other causes of pneumonia, and specific tests are required to make the diagnosis. Currently, testing occurs erratically and, instead, clinicians rely on empiric treatment strategies and ignore public health implications of the diagnosis. We aimed to measure the increase in case detection of Legionnaires...

In this review of the risk of infection to hospital staff, attention is drawn to the continuing risk presented by hepatitis B and pulmonary tuberculosis, which are more common than diseases such as typhoid fever, brucellosis, histoplasmosis, whooping cough, infectious gastroenteritis, measles, and parotiditis. Other items considered include the susceptibility of female hospital staff to rubella...

Legionnaires’ disease is often associated with neurological findings. Despite such findings, computed tomography and neuropathological investigations are typically normal. This report describes a reversible lesion of the corpus callosum identified on magnetic resonance imaging (MRI) in a patient with legionnaires’ disease. MRI may show previously undocumented neuropathology in acute legionnaire...
