“…La detección de anticuerpos para las tres arbovirosis se traslapan clínicamente. Lo anterior obliga a evaluar las tres enfermedades en el sistema de vigilancia de las arbovirosis, para optimizar los recursos de laboratorio según los recursos tecnológicos y financieros disponibles en cada país, así como el modelo de la vigilancia centinela de arbovirosis basada en pruebas virales desarrollada por varios países [26][27][28] .…”

Introducción. Durante el segundo semestre del año 2016 se observó una negatividad del 95% en las pruebas de IgM dengue recibidas en el Laboratorio Nacional de Referencia de El Salvador.Objetivos. Identificar anticuerpos IgM para chikungunya y zika en las muestras de la vigilancia de dengue. Metodología. Se realizó un estudio descriptivo a partir de 438 muestras procedentes de la vigilancia de dengue del 2016, almacenadas en el Laboratorio Nacional de Referencia, cuyo estado serológico de dengue era conocido; se aplicó la técnica de ELISA de captura IgM para virus zika y chikungunya. Resultados. Se identificaron anticuerpos para el virus chikungunya en 95 muestras (22%) y anticuerpos para el virus zika en 25 muestras (6%). Además, 11 muestras (2.6%) fueron positivas para anticuerpos contra el virus ckikungunya y zika. Un caso presento anticuerpos para las tres arbovirosis. Conclusión. En las muestras de la vigilancia del dengue se identificaron anticuerpos para chikungunya y zika. Se encontró la presencia simultánea de chikungunya y zika. La forma de vigilancia actual del dengue encubre otras arbovirosis, las arbovirosis deben vigilarse en conjunto y no como entidades independientes.

“…We mimicked daily prospective analyses for the entire year of 2016 and defined signals using three RI thresholds: 20 days (a low threshold that is sometimes nevertheless used as it corresponds to P < 0.05, failing to account for repeated analyses performed daily instead of once), 100 days (the threshold used by NYC DOHMH for reportable diseases [6]) and 365 days (a threshold sometimes used for less specific data streams, e.g. syndromic surveillance data [25, 26]). Analysis days were restricted to days in which a baseline or simulated case was reported, as only these days had the potential to yield informative signals.…”

Legionnaires’ disease (LD) incidence in the USA has quadrupled since 2000. Health departments must detect LD outbreaks quickly to identify and remediate sources. We tested the performance of a system to prospectively detect simulated LD outbreaks in Allegheny County, Pennsylvania, USA. We generated three simulated LD outbreaks based on published outbreaks. After verifying no significant clusters existed in surveillance data during 2014–2016, we embedded simulated outbreak-associated cases into 2016, assigning simulated residences and report dates. We mimicked daily analyses in 2016 using the prospective space-time permutation scan statistic to detect clusters of ⩽30 and ⩽180 days using 365-day and 730-day baseline periods, respectively. We used recurrence interval (RI) thresholds of ⩾20, ⩾100 and ⩾365 days to define significant signals. We calculated sensitivity, specificity and positive and negative predictive values for daily analyses, separately for each embedded outbreak. Two large, simulated cooling tower-associated outbreaks were detected. As the RI threshold was increased, sensitivity and negative predictive value decreased, while positive predictive value and specificity increased. A small, simulated potable water-associated outbreak was not detected. Use of a RI threshold of ⩾100 days minimised time-to-detection while maximizing positive predictive value. Health departments should consider using this system to detect community-acquired LD outbreaks.

Purpose of review This review describes mosquito-and tick-borne diseases found in the Western Hemisphere. It focuses on emerging diseases and recent geographic shifts in the presence of disease vectors. Recent Findings Mosquito and tick vectors have become more widespread as environmental conditions have become more favorable. Zika recently has emerged as a concern for fetal anomalies. West Nile Virus has become widespread. Lyme disease and other tick-borne diseases are more prevalent in areas previously inhospitable to these ticks. Summary Healthcare providers must consider the possibility of mosquito-and tick-borne diseases in broader geographic areas and council patients traveling to endemic areas on precautions against these diseases. Treatment for suspected cases of serious tick-borne illnesses should not be delayed pending culture results.
