[Neurological symptoms after an infection by the sandfly fever virus].

CASE 1: A few days after returning from a holiday in Italy a 50-year-old man developed acute gastrointestinal symptoms, followed by headache, fever and joint pains. After transitory remission he had a relapse with fever, headache and meningitis 2 weeks later. Cerebrospinal fluid contained gram-negative diplococci, but no bacteria grew on culture. Under the suspected diagnosis of meningitis he was treated with penicillin. Ten days later he suddenly developed deafness in his right ear. The various signs and symptoms gradually disappeared and the patient was discharged after 24 days in hospital. Retrospectively serological tests indicated sandfly fever (SF) virus infection with serotype Toscana. This is thought to be the first reported case of deafness associated with this disease. CASE 2: One week after returning from a holiday in Tunisia a 34-year-old man fell ill with fever, headache, rigor, nausea, joint pains and a maculopapular rash for which he was treated as an outpatient. The symptoms improved after 7 days, except for the headache which persisted another 5 days. Serology demonstrated an acute infection by SF virus, serotype Sicilian.

CONCLUSIONS

Sandfly fever should be included in the differential diagnosis of headache, fever and signs of meningitis in persons who have recently been to mediterranean countries.
