Where Sources Disagree
- Flu Activity Classification: While most reports cite seven states with high flu activity, other coverage distinguishes between one state reaching 'very high' levels and six states reaching 'high' levels.
- Historical Flu Data Context: Most reports state that early-season flu activity is higher than typically observed. In contrast, other reports note that comparisons to the previous year are limited, as health officials had not yet published flu case estimates at this point in the last season.
