The US COVID Atlas shows four types of hot spots:
• High-High: Areas with high numbers whose neighbors also have high numbers. Bright red counties have a significantly high number of cases or deaths, or significantly fewer hospital beds per case. Neighbors for these areas also have a high number of cases.
• Low-Low: Areas with low numbers whose neighbors also have low numbers. Bright blue counties have significantly fewer cases or deaths, or significantly more hospital beds per case. Neighbors for these areas also have a low number of cases.
• High-Low: Areas with high numbers whose neighbors have low numbers. This type of hot spot is also called an outlier, because it differs so much from its neighbors. Pale red counties have more cases, deaths, or fewer hospital beds per case than do their immediate neighbors. The surrounding areas may experience significant spread of the virus in future weeks.
• Low-High: Areas with low numbers whose neighbors have high numbers. This type of hot spot is also called an outlier, because it differs so much from its neighbors. Pale blue counties have fewer cases, deaths, or more hospital beds per case than do their immediate neighbors. These areas may experience significant spread of the virus from surrounding areas in future weeks.
Apart from focusing on High-High cluster counties, attention should also be given to High-Low & Low-High clusters, referred to as Outliers. These areas often highlight an emerging risk or priority for containment.
