Tularemia - Documented Outbreaks

Documented Outbreaks

From May to October 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.

An outbreak of tularemia occurred in Kosovo in 1999-2000.

In 2004, three researchers at Boston University Medical Center were accidentally infected with F. tularensis, after apparently failing to follow safety procedures.

In 2005, small amounts of F. tularensis were detected in the Mall area of Washington, DC the morning after an antiwar demonstration on September 24, 2005. Biohazard sensors were triggered at six locations surrounding the Mall. While thousands of people were potentially exposed, no infections were reported. The detected bacteria likely originated from a natural source, not from a bioterror attempt.

Tularemia is endemic in the Gori region of the Eurasian country of Georgia. The last outbreak was in 2006.

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. Another outbreak had taken place ten years before in the same area.

In August 2009, a Swedish tourist was bitten by an unidentified insect at Point Grey, Vancouver, BC, Canada. It was not until after return to Sweden that he was diagnosed with tularemia, despite seeking medical treatment in Vancouver.

In Jan 2011, researchers searching for brucellosis among feral hog populations in Texas discovered widespread tularemia infection or evidence of past infection in feral hog populations of at least 2 Texas counties, even though tularemia is not normally associated with pigs at all. Precautions were recommended for those who hunt, dress, or prepare feral hogs. Since feral hogs roam over large distances, there is concern that tularemia may spread or already be present in feral hogs over a very wide geographic area.

In June 2011, in Armenia, Mrgahovit village of Lori Marz two people were infected.

In November 2011, it was found in Tasmania, Australia. Reports claimed it to be the first in the southern hemisphere. However, the causative organism was documented to have been isolated from a foot wound in the Northern Territory, Australia in 2003.

There are some hundreds to a thousand outbreaks of tularemia yearly in Finland, the same goes to neighboring Sweden as well.
