“…This also explains the decline in chickenpox, herpes zoster, rubella and measles and the decline in foodborne infections and sexually transmitted diseases [23,24]. Noroviruses are primarily transmitted through direct contact and droplet infection, which could explain the reduction in hygiene measures and contact restrictions to prevent the spread of Covid-19 [10,11]. However, the main viral pathogens of respiratory infections differ only marginally in their properties and size.…”

With SARS-CoV-2 in 2019 a coronavirus started circulating, for which the population showed no specific defense mechanisms of the immune system due to its clear distinction from the previously circulating coronavirus strains. Nevertheless, in 2021 there was a significant decrease in respiratory infections with a simultaneous significant increase in pandemic-related SARS-CoV-2 infections found. There is also a reduction in reported cases of respiratory diseases, especially in the pandemic year 2021. The aim of this study is to show optimizations in the test strategy during a pandemic and thus derive the improvement of civil protection. For Evaluation the data of GrippeWeb, the RKI’s Survstat® tool and the RKI’s reporting data on the new coronavirus were used. In addition, an evaluation of billing data from the EBM from 2017 to 2022 for the GOP 32816 as well as an evaluation of data on sick leave and illness statistics from 2019 to 2021 and the consideration of inpatient and outpatient health costs based on the data requested in writing from the Federal Ministry of Health was performed. The data from the Influenza Working Group shows an average of 300,000 annual reports for ARI per year. In 2019 it increased to 1,985,985 reports, in 2020 (5,453,017) and in 2021 to 29,681,158. There is also a correlation between the SARS-CoV-2 test frequency and the positive results, as well as an increase in the previously 6% positive rate for SARS-CoV-2 to over 50% in 2022. At the same time decreases the medical burden due to acute respiratory diseases (ARI) contrary to the increase of the acute respiratory diseases reported to the RKI with 2684%. What has been neglected so far is that corona viruses (HCoV) have been responsible for around 5-10% of acute respiratory infections for decades. The comprehensive Covid-19 control measures, including the obligation to wear masks, apparently had no significant impact on reducing the spread of Covid-19, since there was also no decrease in infections with the adenovirus or RS virus in 2020 and 2021. Furthermore, an infection positive rate should not be used as a criterion for infection avoidance strategies and the recording of test results should always be validated and controlled. Only the testing of symptomatic persons should be remunerated and only these validated test results should be considered in the registration. In addition, the DIVI register for the inpatient area with recording of the main admission diagnosis and the data from the electronic transmission of sick notes to the health insurance companies for the outpatient area could be used in real time to decide on containment measures in the context of the pandemic

“…corona pandemic, such as lockdown, distance rules and the obligation to wear masks, were discussed as the main reasons for the absence of the annual flu epidemic. In particular, the correct wearing of FFP-2 masks is said to have contributed to reducing infection with influenza viruses [5,9] and noroviruses [10].…”

The end of the 2019/2020 influenza season was already registered in early summer 2020, and in the following season. There was an nearly complete absence of influenza. So far, the sometimes strict Covid-19 containment measures with contact restrictions and the obligation to wear a mask have been mentioned as reasons. The further processing of this influenza gap showed multifactorial reasons also the lack of registration of influenza cases This study looks for further reaseons and from several perspectives in order to develop strategies for a representative recording of influenza cases derive. For Evaluation the data of GrippeWeb, the RKI’s Survstat® tool and the RKI’s reporting data on the new coronavirus were used. In addition, an evaluation of billing data from the EBM from 2017 to 2022 for the GOP 32816 as well as an evaluation of data on sick leave and illness statistics from 2019 to 2021 and the consideration of inpatient and outpatient health costs based on the data requested in writing from the Federal Ministry of Health was performed. In contrast to influenza A/B, the other viral respiratory pathogens (adenovirus, parainfluenza virus and RS virus) do not show any significant reduction. From 2020, the number of reports of respiratory infections to the RKI increased from an average of 300,000 annual reports by 2019 to 1,985,985 reports in 2020, over 5,453,017 reports in 2021 and to 29,681,158 in 2022. On the other hand cases of incapacity to work due to respiratory infections fell from 31.0% in 2019 to 15.3% in 2021. Influenza-specific diagnoses (ICD: J10.1-3) were encrypted 33,727 times in 2021, in 2020 there were still 109,846. In the outpatient sector in particular, the treatment costs are falling from 2019 to 2021. The reduction in influenza A and B from 2020 as a result of the comprehensive Covid-19 control measures, including the obligation to wear masks, cannot be considered a major reason; rather, the aspect of underreporting of influenza cases plays a significant role. Therefore, the reporting quantity of the sentinal practices should be considered and the recording of incapacity diagnoses should be taken into account.
