Historical Perspective
Franciscella tularensis was discovered in 1911 during an outburst of rabbit fever, when the disease killed a large number of ground squirrels in the area of Tulare Lake in California. Scientists determined that tularemia could be dangerous to humans: a human being may catch the infection after contacting an infected animal. The ailment soon became frequent with hunters, cooks and agricultural workers.[2]
Documented outbreaks
In summer 2000, an outbreak of tularemia in Martha's Vineyard resulted in one fatality, and brought the interest of the CDC as a potential investigative ground for aerosolized Francisella tularensis. Over the following summers, Martha's Vineyard was identified as the only place in the world where documented cases of tularemia resulted from lawn mowing.[1] The research may prove valuable in preventing bioterrorism.
An outbreak of tularemia occurred in Kosovo in 1999-2000 [3].
In 2004, three researchers at Boston University Medical Center were accidentally infected with F. tularensis, after apparently failing to follow safety procedures.[2]
In 2005, small amounts of F. tularensis were detected in the Mall area of Washington, DC the morning after an anti-war demonstration on September 24, 2005. Biohazard sensors were triggered at six locations surrounding the Mall. To this date, no cases of tularemia infection have been reported as a result.[3]
In 2007, a lab of Boston University's Center for Advanced Biomedical Research, where F. tularensis were being kept for research, was evacuated after smoke set off alarms. An investigation has later determined that an electrical problem was the culprit, and no bacterial contamination was found.
In July 2007, an outbreak was reported in the Spanish autonomous region of Castile and León and traced to the plague of voles infesting the region.

A week after six bioterrorism sensors detected the presence of a dangerous bacterium on the Mall, health officials said there are no reports that any of the thousands of people in the nation's capital Sept. 24 have tularemia, the illness that results from exposure to the bacteria.
