发热与不发热呼吸道疾病成人患者流感的检测

Detection of influenza virus in adult patients with fever and without fever

目的应用快速筛查法对发热及不发热的成人呼吸道疾病患者的甲型流感病毒(Flu A)、乙型流感病毒(Flu B)进行检测并结果分析,以了解流感病毒的流行及分布情况,为流感的防治奠定基础。方法对860例不发热呼吸道疾病成人患者和发热门诊407例发热成人患者鼻咽分泌物样本进行Flu A和Flu B的快速筛查检测,并对检测结果进行统计学分析。结果不发热病人Flu A检出率为9.5%,Flu B检出率为4.4%,发热病人Flu A检出率为32.9%,Flu B检出率为5.2%。发热病人的Flu A检出率明显高于不发热病人(P<0.01),而Flu B检出率二者则没有显著差异(P>0.05)。结论 Flu A和Flu B是呼吸道感染的重要病原体,并且能够共同流行,发热是其感染的重要症状之一,应用流感快速筛查的方法能够为临床提供一定的早期诊断依据。

Objective To investigate the distribution of influenza virus through rapid detecting and analyze the flu A and flu B in adult patients with fever and without fever,and provide a supporting theory of its prevention.Methods Flu A and flu B in 860 adult respiratory tract infection patients without fever and 407 adult patients with fever during were performed through rapid detection.Results Detection rates of flu A and flu B were 9.5% and 4.4% in the 860 patients without fever respectively.The rates were 32.9% and 5.2% in the 409 patients with fever respectively.The detection rate of flu A in the patient with fever was significantly higher than that in the patients without fever（P0.01）.There was no significant deference of detection rate of flu B between those two groups（P0.05）.Conclusion Flu A and B are important pathogens in respiratory tract infection and can show epidemic together.Fever is one of the most important symptoms in influenza virus infection patients.Using rapid detection can provide basis for early diagnosis and correct therapy.
