Important Notes Data about COVID-19 and influenza cases are extracted from PHIMS. Numbers are subject to change. Missed events in the current report due to reporting delays will be included in later reports when data become available. Cumulative totals include all events from start of the current season to end of the reporting week. ICU admissions are included in hospital admissions, and include adult and pediatric cases. RSV - Respiratory syncytial virus. Influenza associated hospitalizations and associated ICU cases are currently under review. COVID case counts are under review and maybe an undercount. Deaths are reported as “associated with” COVID or Influenza, but not all have been “caused by” COVID or Influenza. “COVID associated deaths” and “Influenza associated deaths” include persons who had a confirmed positive lab test result for COVID or Influenza, within 30 days before their death, or following their death through a post mortem. The number of deaths from week to week may be impacted by the lag-time for entry of deaths from Vital Statistics/Client Registry/clinical notifications and delayed entry of cases.
