Tularemia in Children, Turkey, September 2009–November 2012
Tularemia, caused by Francisella tularensis, is a potentially fatal, multisystemic disease in humans. Tularemia occurs throughout most of the Northern Hemisphere, and the number of cases is increasing in various parts of Europe, especially in the Balkans, Turkey, and Scandinavian countries. There are 4 recognized subspecies of F. tularensis, which differ in their pathogenicity and geographic distribution: tularensis (type A), holarctica (type B),novicida, and mediasiatica. Among them, subspecies tularensis and holarctica are of particular clinical and epidemiologic relevance (1–4). Although the highly virulent subspecies tularensis is restricted almost exclusively to North America, subspecies holarctica is found in Europe, Asia, and North America and represents the most common subspecies involved in human and animal infection (4).
The clinical forms of tularemia are ulceroglandular or glandular, oculoglandular, oropharyngeal, respiratory, and typhoidal (1). Each form somehow reflects the mode of transmission. The clinical picture and severity of the disease in humans vary considerably depending on the route of infection, the virulence of the causative organism, and the immune status of the host. The ulceroglandular form has been reported as the most prevalent clinical form of the disease in northern Europe, whereas the oropharyngeal form has been most commonly reported in Turkey, Bulgaria, and Kosovo and is attributed to the consumption of contaminated water and food (5–10).
Tularemia is endemic to Turkey, and most cases are reported to occur in late summer or early autumn (10). Various studies on clinical course, treatment, and treatment failure in elderly patients are available in the literature (7,10–12). However, the clinical course of tularemia in children is not well known, and cases in children are often misdiagnosed. Our aim was to demonstrate the clinical features and outcomes for children with tularemia.
Dr Tezer is a physician at the Gazi University School of Medicine hospital. His research interest is zoonotic diseases, especially tularemia and Crimean-Congo hemorrhagic fever.
