研究概览
简要总结
The purpose of this study is to assess the prevalence, strain circulation and disease burden of seasonal Influenza A and B in Panama, selected countries of Central America and the Caribbean from the Year 2010 to 2015.
详细描述
The Gorgas Memorial Institute for Health Studies (ICGES) is a public health institution established in Panama dedicated to health research and disease prevention. It has been performing virological isolations of influenza and is a part of the World Health Organisation (WHO) Global Influenza Surveillance and Response System (GISRS) and a direct collaborator of the Centre for Disease Control and Prevention (CDC).
From 2010 a sentinel surveillance program is being conducted in Panama within the ICGES to collect data on influenza and other respiratory viruses using CDC guidance for Respiratory Disease Surveillance. This study aims to utilize this data source for analyzing the burden of influenza within the region.

主要结局
Number of Seasonal Influenza A and /or B Cases by Age Group, in Panama (Using the Data Reported Via National Influenza Surveillance Program)
时间窗: From January 2011 to December 2017
The case definition of Influenza was any clinical specimen confirmed by a positive laboratory test. Cases were stratified by the following age categories: less than (\<) 2 years; 2-4 years; 5-19 years; 20-39 years; 40-59 years; greater than of equal to (≥) 60 years and Unspecified age, instead of \<1, 1-4, 5-9, 10-14, 15-19, 20-24, 25-44, 45-49, 50-59, 60-64 and ≥ 65 years, as initially described in the Protocol. Note that one specimen sample was positive for both influenza A and B so the number started still remains 1839.
Number of Seasonal Influenza B Cases by Strain Lineage, in Panama (Using the Data Reported Via National Influenza Surveillance Program) Among All Influenza Cases A and/or B
时间窗: From January 2011 to December 2017
The case definition of Influenza was any clinical specimen confirmed by a positive laboratory test. Cases were stratified by lineage (Victoria and Yamagata) and the following age categories: less than (\<) 2 years; 2-4 years; 5-19 years; 20-39 years; 40-59 years; greater than of equal to (≥) 60 years. Note that one specimen sample was positive for both influenza A and B so the number started still remains 1839.
Number of Seasonal Influenza A Cases by Virus Subtypes, in Panama (Using the Data Reported Via National Influenza Surveillance Program) Among All Influenza Cases A and/or B
时间窗: From January 2011 to December 2017
The case definition of Influenza was any clinical specimen confirmed by a positive laboratory test. Cases were stratified by virus subtype (H1N1 and H3N2) and the following age categories: less than (\<) 2 years; 2-4 years; 5-19 years; 20-39 years; 40-59 years; greater than of equal to (≥) 60 years. Note that one specimen sample was positive for both influenza A and B so the number started still remains 1839.
