Earlier this year, we discussed an outbreak of Legionnaires’ disease in Wales. A new outbreak has been identified in Spain’s capital of Madrid. The Ministry of Health reports 40 confirmed cases and 3 deaths to date due to Legionella. This disease usually appears as a pulmonary infection with symptoms of high fever and pneumonia. It is not spread from person to person, but typically spreads through contaminated water (from cooling-towers, whirlpools, aerosol sources). Officials in Madrid continue to investigate the source of the outbreak in an attempt to control it.
