After reaching peak in mid-March, the seasonal influenza still remains at high overall levels across China with a few provinces passing an inflection point with cases declining, the Chinese National Influenza Center (CNIC) said.

Statistics from the Chinese Center for Disease Control and Prevention (China CDC) show that 53.2 percent people examined at sentinel hospitals with cold symptoms testing positive for the pathogen during the 10th week of 2023, much higher than the 0.7 percent in the fifth week.

Wang Dayan, the director of the CNIC, said on Monday that influenza activities began to increase in early February, and the rising momentum became apparent after the end of February with the transmission of the influenza virus nationwide entering its peak in mid-March, the Beijing Daily reported.

Although the level of influenza activity currently remains at a high level, China CDC has also detected an inflection point, which represents declining of the virus in a number of provinces, Wang said.

According to Wang, the flu season this year was about two months later than previous years with influenza A (H1N1) as the dominant virus followed by influenza A (H3N2).

The latest data from China CDC shows that flu positivity rates at hospitals monitored in the week ending March 12 climbed to 53.2 percent, much higher than a month earlier, which is different from the usual situation that flu spreads in winters rather than in springs.

In terms of viral prevalence, China’s flu season usually starts around the end of November, peaks in January and lasts until March, according to Wang.

However, due to the COVID-19 epidemic spiking in last December and this January, prevention and control measures against coronavirus were also effective in guarding against seasonal flu and other respiratory viruses to some degree, Wang said.

中疾控:本轮流感3月中旬进入高峰期,部分省份已出现拐点

冬季是流感高发季,为什么刚过去的冬季没有流感流行,最近反而出现了?流感的流行态势怎么样?流感病毒是主要感染儿童吗?

针对公众关心的流感防治热点问题,我们特别邀请中国疾控中心病毒病所国家流感中心主任王大燕为大家答疑解惑。

Q:最近流感的流行态势怎么样?

A:流感是流行性感冒的简称,是指由流感病毒引起的急性呼吸道传染病。流感病毒可造成每年的季节性流行和不定期的全球流感大流行,虽然流感病毒的型别和亚型众多,但在人群中能够导致季节性流行的就是甲型H1N1、H3N2亚型和乙型流感病毒。

此次流感活动水平在2023年2月初开始升高,2月底后上升趋势明显,到3月中旬已经进入高峰期。虽然目前整体仍处于高位,但我们也监测到有几个省份流感活动高峰已经出现拐点,开始下降。今年较往年约晚2个月进入流感流行季,本次流行的流感病毒以甲型H1N1亚型流感病毒为主,其次为甲型H3N2亚型流感病毒。
