RESUMO
BACKGROUND: Exanthematic diseases are a group of syndromes mainly caused by acute viral infections. AIM: To obtain information about the viruses that cause exanthematic diseases in our region. PATIENTS AND METHODS: During 1998, 267 serum samples from patients with an acute rash or patients presenting a febrile syndrome accompanied by enlarged lymph nodes, headache and other symptoms, were collected. Specific antibody of the IgM class (anti-IgM) against Rubella, Measles, Dengue types 1-4 and Cytomegalovirus (CMV) were measured by immunoenzymatic assay (EIA). Epstein-Barr virus (EBV) antibodies were measured by immunofluorescence. RESULTS: An etiologic agent was detected in 208 cases (77.9%). Cases due to Dengue (40.6%) and Rubella (21%) viruses predominated, but the frequency of other agents was also high in specific age groups. The agreement between the clinical suspicion and the laboratory findings varied broadly, from a 100% for suspected Dengue to just a 14.8% for cases of suspected CMV infection. CONCLUSIONS: Dengue was the most common viral exanthematic disease in the Zulia State during 1998.

FUNDAMENTO: Para esclarecer el inesperado aumento en el año 2000 de meningitis linfocitarias analizadas en el Centro Nacional de Microbiología, se revisan sus hallazgos microbiológicos. PACIENTES Y MÉTODO: Las muestras de 732 pacientes fueron procesadas por técnicas virológicas y serológicas para detectar infecciones por agentes neurotropos. RESULTADOS: Se identificaron infecciones en 375 casos (51 per cent). El 90 per cent de los positivos correspondieron a enterovirus no polio. Se caracterizaron principalmente Echovirus 30 y 13, este último por primera vez en España. CONCLUSIONES: La emergencia del Echovirus 13 puede explicar la situación epidémica pasada (AU)
