Resumo: | A leptospirosis clinical-epidemiological study was made in humans and reservoirs in the state of Yucatán, México. Interviews and serological analyses were made on 400 persons from an open population, 439 probable cases of leptospirosis and 1060 animal reservoirs (cows, pigs, dogs, rats and opossums). IgM Leptospira DipstickTM and Microscopic Agglutination Test (MAT) was used to detect human antibodies to leptospiras and serovar respectively. Leptospirosis incidence in humans was 2.2/100,000 inhab. in 1998, 0.7/100,000 in 1999 and 0.9/100,000 in 2000. Overall seroprevalence was 14.2%, relatively unchanged from seroprevalences observed 20 years ago. Highest seropositivity was found in people over 56 years of age, predominating males over females. Predominant serovars in the open population were tarassovi, hardjo, pomona and panama. Leptospirosis cases were most frequent in rural areas, and the anicteric course predominated over the icteric. The panama, icterohaemorrhagiae and pomona serovars predominated in both anicteric and icteric courses. Dogs, pigs and rodents had the highest seropositivity among the reservoirs. Contact with rodents and natural water sources were significant factors (p ;£; 0.05). Human cases (74%) occurred during the rainy season. It is concluded that leptospirosis is still a serious illness with important clinical and epidemiological implications in the state of Yucatán, Mexico. |

Un estudio clínico-epidemiológico de leptospirosis fue realizado en humanos y reservorios en el estado de Yucatán, México. Se entrevistaron y analizaron mediante serología 400 personas en población abierta, 439 pacientes sospechosos y 1060 reservorios (bovinos, cerdos, perros, roedores y zarigüeyas). En humanos para la detección de anticuerpos se utilizó IgM Dipstick LeptospiraTM y la prueba de aglutinación microscópica (MAT) para detectar serovar. La incidencia en humanos fue de 2.2/100,000, 0.7/100,000 y 0.9/100,000 habitantes para los años 1998, 1999 y 2000 respectivamente y la seroprevalencia de 14.2%. La frecuencia más alta de seropositivos se encontró en mayores de 56 años, predominando el sexo masculino sobre el femenino. Predominó en población abierta el serovar tarassovi siguiendo en importancia hardjo, pomona y panamá. Los casos fueron más frecuentes en el área rural y el curso anictérico predominó sobre el ictérico. Panamá, icterohaemorrhagiae y pomona predominaron en ambos cursos de la enfermedad. Los perros cerdos y roedores tuvieron mayor positividad. El contacto con roedores y depósitos naturales de agua fue significativo (p ;£; 0.05). El 74.3% de los casos se presentaron en época de lluvia. En conclusión la leptospirosis en Yucatán, México, sigue siendo una entidad patológica de importancia tanto clínica como epidemiológica.
