Spatial distribution of outbreak-associated cases of hepatitis A and invasive meningococcal disease in an investigation of concurrent outbreaks in Florida, 2021 to 2022. (A) Locations of cases by postal (ZIP) code of patient residence; (B) detail of box from central Florida in panel A, in which more than one case of each disease were reported in the same postal code. Outside the area represented in that panel, no instances of both diseases were identified in the same postal code. Invasive meningococcal disease cases were georeferenced by postal code centroid. Small polygons are outlines of postal code areas. Light gray lines indicate county borders; dark gray lines indicate postal areas where cases were identified.
