ARE-Wochenbericht
Kalenderwoche 39 (26.9. bis 2.10.2022)
Zusammenfassende Bewertung der epidemiologischen LageMit diesem ARE-Wochenbericht endet die Berichterstattung für die Saison 2021/22. Ab der nächsten
Woche beginnt die wöchentliche Berichterstattung für die neue Saison 2022/23.
Die Aktivität der akuten Atemwegserkrankungen (ARE-Raten) in der Bevölkerung (GrippeWeb) ist in der
39. KW 2022 im Vergleich zur Vorwoche leicht gestiegen. Die Werte liegen aktuell deutlich über den
Werten der Vorsaisons. Im ambulanten Bereich (Arbeitsgemeinschaft Influenza) wurden in der 39. KW
bundesweit deutlich mehr Arztbesuche wegen ARE als in der Vorwoche registriert. Die Zahl der Arzt-
besuche liegt über dem Niveau der Vorjahre (seit 2006) um diese Zeit.
Im NRZ für Influenzaviren wurden in der 39. KW 2022 in insgesamt 59 (58 %) der 101 eingesandten
Sentinelproben respiratorische Viren identifiziert, darunter 32 (32 %) Proben mit Rhinoviren, jeweils zwölf
(12 %) mit SARS-CoV-2 bzw. mit Parainfluenzaviren (PIV), sechs (6 %) mit Influenzaviren, drei (3 %) mit
Respiratorischen Synzytialviren (RSV) und eine (1 %) Probe mit humanen saisonalen Coronaviren (hCoV).
Humane Metapneumoviren (hMPV) wurden nicht nachgewiesen.
Im Rahmen der ICD-10-Code basierten Krankenhaussurveillance (ICOSARI) ist die Zahl schwerer
akuter respiratorischer Infektionen (SARI) in der 39. KW 2022 insgesamt leicht gesunken und liegt weiter-
hin auf dem Niveau der vorpandemischen Jahre. Der Anteil der mit schwerer Atemwegserkrankung
hospitalisierten Patienten mit einer COVID-19-Diagnose ist im Vergleich zur Vorwoche stabil geblieben
und lag in der 39. KW bei 29 %.
Die für diese Jahreszeit außergewöhnlich hohe ARE-Aktivität ist auf die Ko-Zirkulation verschiedener
Atemwegserreger zurückzuführen, darunter hauptsächlich Rhinoviren, aber auch SARS-CoV-2 und Para-
influenzaviren. Zunehmend werden auch Influenzaviren und RSV nachgewiesen.
Elevated vascular transformation blood biomarkers in Long-COVID indicate angiogenesis as a key pathophysiological mechanism - Molecular Medicine
Background Long-COVID is characterized by prolonged, diffuse symptoms months after acute COVID-19. Accurate diagnosis and targeted therapies for Long-COVID are lacking. We investigated vascular transformation biomarkers in Long-COVID patients. Methods A case–control study utilizing Long-COVID patients, one to six months (median 98.5 days) post-infection, with multiplex immunoassay measurement of sixteen blood biomarkers of vascular transformation, including ANG-1, P-SEL, MMP-1, VE-Cad, Syn-1, Endoglin, PECAM-1, VEGF-A, ICAM-1, VLA-4, E-SEL, thrombomodulin, VEGF-R2, VEGF-R3, VCAM-1 and VEGF-D. Results Fourteen vasculature transformation blood biomarkers were significantly elevated in Long-COVID outpatients, versus acutely ill COVID-19 inpatients and healthy controls subjects (P
RKI - Influenza - Wie hoch ist die Wirksamkeit der Influenza-Impfung?
Die Wirksamkeit der Influenza-Impfung kann in jeder Saison sehr unterschiedlich sein und sich auch hinsichtlich der einzelnen Virustypen sowie -subtypen unterscheiden. Die Impfeffektivität hängt dabei von verschiedenen Faktoren ab. Hierzu gehören beispielsweise das Alter des Impflings, frühere Influenza-Infektionen oder -Impfungen oder auch die Art des verwendeten Impfstoffes.
Age-stratified infection fatality rate of COVID-19 in the non-elderly informed from pre-vaccination national seroprevalence studies
The infection fatality rate (IFR) of COVID-19 among non-elderly people in the absence of vaccination or prior infection is important to estimate accurately, since 94% of the global population is younger than 70 years and 86% is younger than 60 years. In systematic searches in SeroTracker and PubMed (protocol: ), we identified 40 eligible national seroprevalence studies covering 38 countries with pre-vaccination seroprevalence data. For 29 countries (24 high-income, 5 others), publicly available age-stratified COVID-19 death data and age-stratified seroprevalence information were available and were included in the primary analysis. The IFRs had a median of 0.035% (interquartile range (IQR) 0.013 - 0.056%) for the 0-59 years old population, and 0.095% (IQR 0.036 - 0.125%,) for the 0-69 years old. The median IFR was 0.0003% at 0-19 years, 0.003% at 20-29 years, 0.011% at 30-39 years, 0.035% at 40-49 years, 0.129% at 50-59 years, and 0.501% at 60-69 years. Including data from another 9 countries with imputed age distribution of COVID-19 deaths yielded median IFR of 0.025-0.032% for 0-59 years and 0.063-0.082% for 0-69 years. Meta-regression analyses also suggested global IFR of 0.03% and 0.07%, respectively in these age groups. The current analysis suggests a much lower pre-vaccination IFR in non-elderly populations than previously suggested. Large differences did exist between countries and may reflect differences in comorbidities and other factors. These estimates provide a baseline from which to fathom further IFR declines with the widespread use of vaccination, prior infections, and evolution of new variants. Highlights *Across 31 systematically identified national seroprevalence studies in the pre-vaccination era, the median infection fatality rate of COVID-19 was estimated to be 0.035% for people aged 0-59 years people and 0.095% for those aged 0-69 years. *The median IFR was 0.0003% at 0-19 years, 0.003% at 20-29 years, 0.011% at 30-39 years, 0.035% at 40-49 years, 0.129% at 50-59 years, and 0.501% at 60-69 years. *At a global level, pre-vaccination IFR may have been as low as 0.03% and 0.07% for 0-59 and 0-69 year old people, respectively. *These IFR estimates in non-elderly populations are lower than previous calculations had suggested. ### Competing Interest Statement The authors have declared no competing interest. ### Funding Statement The work of John Ioannidis is supported by an unrestricted gift from Sue and Bob O Donnell.

As Omicron mutates wildly the virus shows first signs of convergent evolution
Over the last couple of months researchers tracking emerging SARS-CoV-2 variants have started noticing something strange. No one new variant has looked like taking over but instead a variety of different subvariants seemed to be accumulating the same mutations.

Incidence of Myocarditis/Pericarditis Following mRNA COVID-19 Vaccination Among Children and Younger Adults in the United States | Annals of Internal Medicine
Background: Vaccine safety monitoring systems worldwide have reported cases of myocarditis/pericarditis after mRNA-based COVID-19 vaccines (Pfizer-BioNTech and Moderna), especially among younger male persons 0 to 7 days after they received dose 2 (1, 2). Less is known about the incidence of myocarditis/pericarditis after booster doses.
Objective: To estimate the incidence of myocarditis/pericarditis during days 0 to 7 after mRNA vaccination by age, sex, dose number, and product.

Protective effectiveness of prior SARS-CoV-2 infection and hybrid immunity against Omicron infection and severe disease: a systematic review and meta-regression
Background We aimed to systematically review the magnitude and duration of the protective effectiveness of prior infection (PE) and hybrid immunity (HE) against Omicron infection and severe disease. Methods We searched pre-print and peer-reviewed electronic databases for controlled studies from January 1, 2020, to June 1, 2022. Risk of bias (RoB) was assessed using the Risk of Bias In Non-Randomized Studies of Interventions (ROBINS-I)-Tool. We used random-effects meta-regression to estimate the magnitude of protection at 1-month intervals and the average change in protection since the last vaccine dose or infection from 3 months to 6 or 12 months. We compared our estimates of PE and HE to previously published estimates of the magnitude and durability of vaccine effectiveness (VE) against Omicron. Findings Eleven studies of prior infection and 15 studies of hybrid immunity were included. For prior infection, there were 97 estimates (27 at moderate RoB and 70 at serious RoB), with the longest follow up at 15 months. PE against hospitalization or severe disease was 82.5% [71.8-89.7%] at 3 months, and 74.6% [63.1-83.5%] at 12 months. PE against reinfection was 65.2% [52.9-75.9%] at 3 months, and 24.7% [16.4-35.5%] at 12 months. For HE, there were 153 estimates (78 at moderate RoB and 75 at serious RoB), with the longest follow up at 11 months for primary series vaccination and 4 months for first booster vaccination. Against hospitalization or severe disease, HE involving either primary series vaccination or first booster vaccination was consistently 95% for the available follow up. Against reinfection, HE involving primary series vaccination was 69.0% [58.9-77.5%] at 3 months after the most recent infection or vaccination, and 41.8% [31.5-52.8%] at 12 months, while HE involving first booster vaccination was 68.6% [58.8-76.9%] at 3 months, and 46.5% [36.0-57.3%] at 6 months. Against hospitalization or severe disease at 6 months, hybrid immunity with first booster vaccination (effectiveness 95.3% [81.9-98.9%]) or with primary series alone (96.5% [90.2-98.8%]) provided significantly greater protection than prior infection alone (80.1% [70.3-87.2%]), first booster vaccination alone (76.7% [72.5-80.4%]), or primary series alone (64.6% [54.5-73.6%]). Results for protection against reinfection were similar. Interpretation Prior infection and hybrid immunity both provided greater and more sustained protection against Omicron than vaccination alone. All protection estimates waned quickly against infection but remained high for hospitalisation or severe disease. Individuals with hybrid immunity had the highest magnitude and durability of protection against all outcomes, reinforcing the global imperative for vaccination. ### Competing Interest Statement The authors have declared no competing interest. ### Clinical Protocols ### Funding Statement This work was supported by WHO through funding from the WHO Solidarity Response Fund.
