Esquistosomiasis aguda entre estadounidenses que hacen rafting en el río Omo, Etiopía
JAMA
|January 27, 1984
Resumen
Un brote de esquistosomiasis aguda ocurrió en Etiopía, afectando al 55% de las vigas en el río Omo. El diagnóstico temprano era un desafío, destacando los riesgos para los viajeros a la región.
Área de la Ciencia:
- La medicina tropical es una medicina tropical.
- Enfermedades infecciosas Enfermedades infecciosas.
- Parasitología Parasitología.
Sus antecedentes:
- La esquistosomiasis es una enfermedad parasitaria causada por gusanos planos del género Schistosoma.
- La esquistosomiasis aguda puede presentarse con síntomas no específicos, lo que complica el diagnóstico precoz.
Objetivo del estudio:
- Para informar de un brote de esquistosomiasis aguda entre viajeros en Etiopía.
- Para resaltar los desafíos de diagnóstico asociados con la esquistosomiasis temprana en viajeros.
- Sensibilizar a los proveedores de atención médica sobre los riesgos de la esquistosomiasis en los viajeros.
Principales métodos:
- Un informe descriptivo de una investigación de un brote.
- Identificación de casos clínicos y evaluación sintomológica.
- Confirmación de laboratorio de la infección por Schistosoma mansoni a través del examen de las heces.
Principales resultados:
- Once miembros de una expedición de rafting estuvieron expuestos a una posible esquistosomiasis.
- Se confirmó que seis (55%) personas estaban infectadas con Schistosoma mansoni.
- Cinco personas infectadas presentaron síntomas de esquistosomiasis aguda, incluyendo eosinofilia y fiebre.
- El diagnóstico se retrasó hasta enero de 1982, a pesar de las evaluaciones médicas.
Conclusiones:
- Los viajeros a la región del río Omo en Etiopía están en riesgo de infección por Schistosoma mansoni.
- La esquistosomiasis aguda puede ser difícil de diagnosticar temprano en los viajeros.
- Los médicos deben considerar la esquistosomiasis en el diagnóstico diferencial de enfermedades febriles en viajeros que regresan de áreas endémicas.

00:58Symbiosis
Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...
01:25Cholera
Cholera is an acute gastrointestinal disease caused by the Gram-negative bacterium Vibrio cholerae. It is transmitted primarily via the fecal-oral route through the ingestion of contaminated water or food.Vibrio cholerae is a motile, Gram-negative bacterium of the family Vibrionaceae, primarily associated with waterborne outbreaks in areas with inadequate sanitation. Although over 200 serogroups of V. cholerae exist, only O1 and O139 are responsible for epidemic cholera. The O1 serogroup,...
01:28Toxoplasmosis
Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
01:22American Trypanosomiasis
Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
01:12Giardiasis
Giardiasis is a globally prevalent intestinal infection caused by the protozoan parasite Giardia duodenalis (also known as G. lamblia or G. intestinalis). This flagellated protozoan is the most frequently identified intestinal parasite in the United States and worldwide. Transmission primarily occurs via the fecal-oral route, with infection arising from ingestion of water or food contaminated with cysts. Individuals in low-resource settings, international travelers, outdoor enthusiasts, daycare...
01:28Amebiasis
Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
