Resumen
La provincia de Misiones en 1998 notificó 205 casos de leishmaniosis, 98% en la localidad de Puerto Esperanza. El análisis de las fichas clínicas (n:129) de los casos atendidos en Hospital Puerto Esperanza (enero a septiembre 1998) mostró una mayor proporción de lesión cutánea simple (97,2%), localizada en miembros inferiores (72,5%), sin casos de lesión mucosa. Los resultados fueron coherentes con los de la literatura de otros focos epidémicos en Argentina debidos a Leishmania (V.) Braziliensis. No hubo diferencia significativa de incidencia entre sexos, se registró en todos los grupos etarios, y fue susceptible al tratamiento convencional. El foco principal se registró en el Barrio Km1 con un máximo de transmisión en abril de 1998. La intradermoreacción de Montenegro en población general (n:205) no mostró reactividad en asintomáticos. Se capturaron 577 Phlebotominae pertenecientes a 8 especies, las más abundantes fueron Lutzomyia intermedia (79,7%) y Lu. whitmani (10,9%), presentes en peridomicilios de Km1 asociados a selva paranaense residual y vegetación secundaria. Los resultados se discuten en el marco de estrategias posibles de vigilancia y control.
The province of Misiones reported 205 leishmaniasis cases during 1998, 98% of them from the locality of Puerto Esperanza. The resports of Puerto Esperanza Hospital (January to September 1998) for leishmanuasis were analysed (n:129). The mainly reported lesion was the single cutaneous ulcer (97,2%), localized in the inferior limbs (72,5%), without any mucosa involvement. The reults are consistent with the knowledge from other Argentinean leishmaniasis foci due to Leishmania (V.) braziliensis. The difference in incidence among sexes was not significant, leishmaniasis was reported in all age groups, and it was suceptible to the convenctional treatment. The main focus was located in Km1 neighbourhood, the transmission peak was during April 1998. The Montenegro skin test among general population (m:205) did not show reactivity among asymptomatic people. The prevalent Phlebotominae species was Lutzomyia intermedia (79,7%) and Lu. whitmani (10,9%), among the 577 individuals belonging to 8 species collected. The Phlebotominae were abundant in periodomestic habitats of Km1 neighbourhoood, close to human dwellings, in places associated with residual primary forest and secondary vegetation. The results are discussed in the fram of surveillance and possible control stategies.
