An outbreak of oropharyngeal tularemia with cervical adenopathy predominantly in the left side.

PURPOSE

We describe the epidemiological and clinical characteristics and the efficacy of a delayed initiation to therapy in an oropharyngeal tularemia outbreak in Duzce, Turkey.

MATERIALS AND METHODS

Between March and June 2000, 22 patients with tularemia were diagnosed by microagglutination tests.

RESULTS

Oropharyngeal and ulceroglandular forms of the disease were discovered. Most of the cases were oropharyngeal (19 cases). The most common symptoms were sore throat (95.4%) and fever (90.9%). Lymphadenopathy (95.4%) and pharyngeal hyperemia (81.8%) were usually observed signs. The lymphadenopathies were localized especially in the left cervical region (66.7%), a finding that has not been previously reported in the literature. The time between the onset of the symptoms and diagnosis was 40.7 +/- 22.8 (10 - 90) days. The patients were treated with streptomycin plus doxycycline and ciprofloxacin. The patients' recoveries took up to 120 days.

CONCLUSION

This report describes the first outbreak of tularemia in northwest Turkey. Tularemia may occur in any region where appropriate epidemiological conditions are found and should be kept in mind for differential diagnosis in oropharyngeal symptoms. Late initiation of therapy may delay complete recovery. In this outbreak, cervical lymph nodes predominantly localized on the left side were found, which had not been previously reported.
