OBJECTIVE
to analyze the circulation of respiratory viruses in people living in the metropolitan area of Belo Horizonte, Brazil, and hospitalized in Belo Horizonte from 2011 to 2013.
METHODS
this is a descriptive study of 5,158 patients with Severe Acute Respiratory Syndrome; a comparison was made between the characteristics of confirmed cases and those of discarded cases or cases without swab samples.
RESULTS
Influenza A virus accounted for half the isolated viruses, especially subtype A(H1N1)pdm09 among patients aged 20-59 years old, and subtype A(H3N2) in those aged 60 or over; the most frequently identified respiratory virus among children under five years old was respiratory syncytial virus (65.6%), followed by influenza A virus (21.2%); influenza virus circulated in all seasons of the year and its periods of greatest incidence were interspersed with those of higher Respiratory Syncytial Virus activity.
CONCLUSION
monitoring respiratory viruses contributes to knowledge about periods of virus circulation and the adoption of specific control measures.
目的
分析2011年至2013年居住在巴西贝洛奥里藏特大都市区并在贝洛奥里藏特住院的人群中呼吸道病毒的流行情况。
方法
这是一项对5158例严重急性呼吸综合征患者的描述性研究；对确诊病例与被排除病例或无拭子样本病例的特征进行了比较。
结果
甲型流感病毒占分离出病毒的一半，在20至59岁的患者中尤其以甲型（H1N1）pdm09亚型为主，在60岁及以上患者中以甲型（H3N2）亚型为主；五岁以下儿童中最常鉴定出的呼吸道病毒是呼吸道合胞病毒（65.6%），其次是甲型流感病毒（21.2%）；流感病毒全年都有流行，其高发期与呼吸道合胞病毒活动较高的时期相互穿插。
结论
监测呼吸道病毒有助于了解病毒流行时期并采取特定的控制措施。
