Via Haaretz: Health Ministry issues warning over Dengue fever infection. Excerpt:
The tropical disease dengue fever is on the increase in Israel and it's only a matter of time until it becomes actively infectious here, according to a local expert.
Dengue fever (also known as breakbone fever ) is a virus-caused disease that is spread by mosquitoes. Prof. Eli Schwartz, director of the Center for Travel Medicine and Tropical Diseases at the Sheba Medical Center, Tel Hashomer, recently published an article in the American journal Emerging Infectious Diseases.
Schwartz noted that there has been an upswing in cases of Israelis stricken by the virus abroad and then diagnosed on their return home. The rise in such cases, in areas close to where the mosquito's presence in Israel is also increasing, multiplies the risk that the disease will become actively infectious here, although locally-spread cases have yet to be reported.
Asian tiger mosquito are believed to have found their way to northern Israel in 2002 in cars imported through Eastern Europe; water in the tires provided the mosquitoes with breeding grounds. They spread from the north to the coast, and in 2010 they were even reported in Jerusalem.
While the bite of the Asian tiger mosquito is only slightly more painful than that of the regular variety, the dengue virus may cause gastrointestinal bleeding and loss of body fluids, as well as anaphylactic shock (similar to a life-threatening allergic reaction ) and death.
