Generally, reporting of influenza has been less complete over weeks 51 and 52 due to the holiday period, which reduces consulting rates and reporting to national centres and subsequently onto ECDC. Nevertheless, in week 52/2010, 15 of the 25 countries reported increasing trends of influenza activity.
This issue of the ECDC Communicable Disease Threats Report (CDTR) covers the period 24 -30 July and includes updates on COVID-19, monkeypox, West Nile virus, increase in hepatitis of unknown aetiology in children, mass gatherings in the Birmingham 2022 Commonwealth games, Vibrio growth, Marburg disease, Chikungunya, dengue, and wild poliovirus.
