ABSTRACT

Background: Chagas disease (CD) is transmitted by vectors but can also be transmitted orally through contaminated food, drinks, or meat. The One Health perspective aims to understand the complex interaction between human, animal, and environmental health in controlling disease. This study analyzed risk factors and drew lessons from past outbreaks of orally transmitted CD to develop effective preventive strategies. Methods: A simultaneous mixed methods study was conducted. The study consisted of two phases: an ecological epidemiological analysis at the municipal level using secondary data spanning from 1992 to 2023, and semistructured interviews with health providers and policymakers at the national level in Colombia. The results from both phases were triangulated to gain a comprehensive understanding of the topic. Results: A total of 64 outbreaks, infecting 302 individuals, were reported. Most of these outbreaks (89.2%) were classified as family-related, and they occurred most frequently during the months of April to June (46.6%). It is worth noting that a significant number of these outbreaks took place in municipalities that lacked vector control plans. Risk factors for oral transmission included the location of food preparation, poor housing quality, food preparation water source, the presence of vectors/marsupials, forest type, and climatic variables. Interviews conducted emphasized the importance of implementing outbreak plans and providing staff training to effectively address the issue. Conclusion: A One Health approach strengthening prevention, surveillance, case management and cross-sectoral collaboration is needed to control outbreaks and reduce transmission in Colombia. Preparedness plans and education of health professionals are also important. This study identified modifiable risk factors to guide public health interventions.

ABSTRACT

We present a case of acute phase Chagas disease in a 40-year-old male patient from Vereda Buenos Aires, Municipality of Miraflores, Department of Guaviare. The patient attended the emergency department with fever, headache, asthenia, adynamia and dysuria. The blood smear and urinalysis were positive for symptomatic urinary tract infection, but negative for malaria. Five days later the diagnosis of acute phase Chagas disease was confirmed after a positive result for Trypanosoma cruzi. The patient was treated with nifurtimox and benznidazole, his contacts and risk areas were investigated, an active entomological community and institutional search was carried out, as well as in the reservoirs, finally, laboratory surveillance for possible cases of infection in the community was conducted. Five cases with similar symptoms were identified, but parasitological tests were negative. Health education measures were implemented to prevent the spread of the disease.


Se presenta un caso de enfermedad de Chagas en fase aguda en un paciente masculino de 40 años, procedente de la Vereda Buenos Aires, Municipio de Miraflores, Departamento del Guaviare. El paciente acudió a urgencias con fiebre, cefalea, astenia, adinamia y disuria. Se realizó un frotis de sangre y un análisis de orina, con resultados positivos para infección urinaria sintomática, pero negativos para malaria. Cinco días más tarde se confirmó el diagnóstico de enfermedad de Chagas en fase aguda tras recibir un resultado positivo para Trypanosoma cruzi. El paciente recibió tratamiento con nifurtimox y benznidazol, y se llevó a cabo una investigación de contactos y zonas de riesgo, búsqueda activa comunitaria e institucional, entomológica y de reservorios, y una vigilancia de laboratorio para detectar posibles casos de infección en la comunidad. Se identificaron cinco casos con síntomas similares, pero las pruebas parasitológicas fueron negativas. Se aplicaron medidas de educación sanitaria para prevenir la propagación de la enfermedad.

ABSTRACT

La malaria en Colombia tiene un comportamiento heterogéneo y variable, entre las regiones. Para establecer su comportamiento epidemiológico en la región del Caribe colombiano entre 1960 y 2019 se realizó un estudio observacional, descriptivo y retrospectivo a partir de registros del Ministerio de Salud y otras fuentes secundarias. Se definieron variables epidemiológicas y se elaboraron medidas de frecuencia y tendencia central. Se registraron 155 096 casos. Las décadas con mayor número de casos fueron 1990-1999 (20,5%) y 1980-1989 (18,9%). El promedio de casos por década fue de 25 849,3. Los índices parasitarios más elevados se registraron en 1970 (3,3 por 1000 habitantes) y 1981 (3,9 por 1000 habitantes). La especie Plasmodium vivax fue la más frecuente y la mayoría de la carga por grupos de edad se registró en menores de 29 años, entre 2010-2019. La malaria presentó un patrón endemo-epidémico de baja y muy baja intensidad de transmisión, con una tendencia al descenso.


Malaria has a heterogeneous and variable behavior among Colombian regions. In order to establish its epidemiological behavior in the Colombian Caribbean region between 1960 and 2019, we carried out an observational, descriptive and retrospective study based on records from the Ministry of Health and other secondary sources. We defined epidemiological variables and used measures of frequency and central tendency. A total of 155,096 cases were registered. The decades with the highest number of cases were 1990-1999 (20.5%) and 1980-1989 (18.9%). The average number of cases per decade was 25,849.3. The highest parasite rates were recorded in 1970 (3.3 per 1000 population) and 1981 (3.9 per 1000 population). Plasmodium vivax was the most frequent species and most of the burden by age group was found in people under 29 years of age, between 2010-2019. Malaria showed an endemic-epidemic pattern of low and very low transmission intensity, with a decreasing trend.

ABSTRACT

Resumen La anisakiasis es una enfermedad parasitaria zoonótica causada por el consumo de pescados o mariscos crudos o poco cocidos infectados con nematodos de los géneros Anisakis, Pseudoterranova y Contracaecum. Se describe el primer caso de anisakiasis en Colombia y se resume la literatura médica disponible. Una mujer de 52 años de edad consultó por dolor epigástrico agudo de inicio abrupto, náuseas, vómitos, diarrea y urticaria después de consumir pescado. El examen físico reveló sensibilidad moderada en el epigastrio. El examen de laboratorio evidenció leucocitosis, en tanto que la radiografía simple y el electrocardiograma no reflejaron ninguna anormalidad. El diagnóstico se hizo mediante una endoscopia de vías digestivas altas, la cual reveló engrosamiento de la pared gástrica y un parásito en movimiento. Se encontró una larva de Anisakis y se la extrajo por endoscopia, lo que alivió el dolor de la paciente. Clínicamente, la anisakiasis puede presentarse como una enfermedad gástrica, intestinal, en otros sistemas o alérgica. El diagnóstico se hace con base en la elaboración del historial alimentario del paciente y la visualización directa de las larvas; el único tratamiento efectivo consiste en su extracción endoscópica.


Abstract Anisakiasis is a zoonotic parasitic disease caused by consumption of raw or undercooked fish or seafood infected with nematodes of the Anisakis, Pseudoterranova or Contracaecum genera. Here, we describe the first case of anisakiasis in Colombia and summarize the available literature. A 52-year-old female with a history of abrupt-onset sharp epigastric pain, nausea, vomit, diarrhea, and urticaria following fish consumption consulted the health service. The physical examination revealed moderate tenderness of the epigastric region; the laboratory evaluation showed leukocytosis and a simple X-ray and ECG showed no abnormalities. The diagnosis was made by endoscopic examination, which revealed a thickened gastric wall and a moving larval worm. An Anisakis larva was found and extracted endoscopically, which relieved the pain of the patient. Clinically, anisakiasis may present as a gastric, intestinal, extragastrointestinal or allergic disease. Diagnosis and treatment of anisakiasis are made by a dietary history, direct visualization and endoscopic extraction of possible larvae, which is the only effective therapy.
