Article Synopsis
- Symptom-only definitions for COVID-like illnesses fail to differentiate between COVID-19, influenza, and other respiratory infections due to overlapping symptoms.
- A new statistical method was developed to attribute cases of acute respiratory infections (ARI) to either influenza or SARS-CoV-2 without relying solely on symptom definitions, using data from the Netherlands in early 2022.
- The model estimated that during the analysis period, 35.4% of ARI cases were attributable to influenza and 27.0% to SARS-CoV-2, highlighting its potential for use in other countries with similar surveillance systems.
Article Synopsis
- The COVID-19 pandemic led to significant health challenges worldwide, prompting measures to reduce infections that had unintended negative effects on public health, particularly among youth.
- This study aimed to utilize an existing syndromic surveillance system in the Netherlands to monitor health issues in young people related to the pandemic, analyzing data quarterly since August 2021.
- Results indicated a notable increase in youth consultations for mental health issues, such as depression and suicide attempts, which correlated with periods of stricter COVID-19 restrictions, indicating the importance of ongoing health monitoring during crisis situations.

- After COVID-19 restrictions were lifted in 2022, the incidence of invasive group A streptococcal (iGAS) infections increased among children and adults, linked to a rise in other viral infections like influenza and varicella.
- A study in the Netherlands aimed to quantify how much skin and soft tissue infections (SSTI) and pneumonia/sepsis cases in children and adults were connected to these viral infections.
- Findings showed that from 2010-2023, varicella was responsible for a significant portion of GAS SSTI cases, while influenza A was the main viral contributor to pneumonia/sepsis, indicating the need for public health interventions like vaccinations to mitigate iGAS infection rates.
We aimed to estimate the impact of influenza vaccination in the Netherlands using general practitioner medical records for 2011-2020. We found that vaccinees had higher consultation rates for influenza-like-illness, acute respiratory infections, and pneumonia, as well as antibiotic use, hospitalisations, and several control diagnoses (i.e.
