Key Points
Bronchiolitis in Children Under 1 Year of Age
- Bronchiolitis indicators were at baseline levels and lower than those observed during the same period last year, both in the community and in the hospital. Virology data indicated low circulation of RSV in the region. However, other viruses capable of causing bronchiolitis are currently circulating, such as rhinoviruses and enteroviruses.
Flu-like Illnesses
- All influenza indicators remained at baseline levels in Week 41, with little detection of influenza virus according to virology data.
COVID-19
- COVID-19 indicators have been on the rise in both community-based medical practice and hospitals since Week 35, though levels remain significantly lower than those observed during the same period in the past two years. Virology data also indicate an increase in SARS-CoV-2 viral circulation over the past three weeks, as does wastewater surveillance.
Acute Gastroenteritis
- No notable increase in indicators has been observed.
