Flu wave in Germany earlier than usual

Ztwice the flu epidemic in Germany largely stayed away – now the influenza is back, and relatively early. Quite high numbers of cases have been reported for a few weeks. According to the definition of Robert Koch Institute (RKI) the flu wave started in the last week of October. This emerges from the weekly report on acute respiratory diseases on Wednesday evening.

The results from a monitoring system in which samples from people with acute respiratory diseases are examined are decisive for the assessment. Various pathogens are routinely checked, such as rhinoviruses, Sars-CoV-2 and influenza. The RKI explains the definition of the beginning of the wave as follows: “In very simplified terms, one can say: If influenza viruses are actually detected in every fifth patient sample, the flu wave has started.”

“During the past few months, significantly more influenza reports have been sent to the RKI than in the pre-pandemic seasons at this time,” the report continues. This is probably based, among other things, on the recommendation since the corona pandemicthat respiratory symptoms should also be tested for influenza viruses. So far, more than 2,100 flu cases have been reported for the past week – and a total of around 8,330 since the start of the season in October. A particularly large number of reports came from Bavaria and North Rhine-Westphalia. There are also reports of 13 outbreaks with at least five cases, for example in schools and kindergartens.

Influenza often doesn’t start until January

The Annual flu epidemic According to the RKI, in the years before Corona, it usually began in January and lasted three to four months. In the past two seasons, however, the pandemic and the measures taken to counteract it have changed the usual course significantly: In 2020/21 there was no flu epidemic worldwide. And in 2021/22 there was not a wave of the usual scale in Germany either, the number of registrations only rose after the Easter holidays and therefore very late.

Even if there were recent warnings of an impending heavy wave: The RKI and other experts emphasize that the course cannot be predicted. However, according to the RKI, it is “conceivable” that the population and/or an increased proportion of the population is susceptible to the pathogens, as stated on the institute’s website. Other experts had spoken of catch-up effects to be expected. That means: If you haven’t had a real flu for a long time, you could now be due again.
