Following is a summary of the influenza situation by sub-regions (listed alphabetically) in the Region of the Americas. More detailed information on the situation of influenza and other respiratory viruses can be obtained from the PAHO/WHO Regional Influenza Update, published weekly, on the PAHO/WHO website at: www.paho.org/influenzareports. In the Andean sub-region, in early 2018, influenza circulated early and intensely in Ecuador, with a predominance of influenza A(H1N1)pdm09. The hospitalization counts in Ecuador increased this year as compared to prior years. In Peru, during the first three weeks of 2018, among the circulating influenza viruses, there was a mix of influenza A(H1N1)pdm09, influenza A(H3N2), and influenza B. Recently, in Bolivia increases in influenza were observed in the department of Santa Cruz, although the hospitalization counts remain comparable to 2017. A continuación, se presenta un resumen de la situación de influenza por subregiones (listadas por orden alfabético). Información más detallada sobre la situación de influenza y otros virus respiratorios se puede obtener en la Actualización Regional de influenza, que se publica semanalmente en la página web de la OPS/OMS, disponible en: http://www.paho.org/reportesinfluenza. En la subregión de América Central, tanto Costa Rica como Guatemala notificaron casos de influenza en los primeros meses de 2018. En Costa Rica la transmisión que se había iniciado a finales de 2017 continúo durante 2018 aunque con una tendencia decreciente a partir de la semana epidemiológica (SE) 4 de 2018, el virus predominante fue influenza A(H3N2). En Guatemala, el porcentaje de positividad se incrementó a partir de la SE 9 de 2018, con circulación concomitante de influenza A(H1N1)pdm09 e influenza A(H3N2). La tasa de hospitalizaciones por influenza registradas en ambos países fue similar a lo reportado en años anteriores.
