Other mainland regions remain at baseline for bronchiolitis, and respiratory syncytial virus positivity rates remain very low, according to the agency.

Influenza also remains at baseline across mainland regions. For COVID-19, the agency reports a slight increase in hospital indicators, while community indicators are stable or declining. This surveillance snapshot does not establish how intense activity will be in the coming weeks.
