Acute Respiratory Infection

Acute Respiratory Infection

General Information

Acute respiratory infection refers to infection caused by respiratory viruses including SARS-CoV-2, influenza, RSV and other respiratory viruses eg human metapneumovirus.

The respiratory virus season in the Northern Hemisphere runs from October (Week 40) of one calendar year to May (Week 20) of the next calendar year (for instance from week 40 2023 to week 20 2024). Based on historical surveillance data, we know that respiratory viruses are most likely to circulate at detectable levels during this time period however, in Ireland we monitor respiratory viruses all year round.
