Following the announcement of the spread of the mosquito-borne Zika virus in an additional one-square-mile area in Miami-Dade County, Fla., the Centers for Disease Control and Prevention has created a new map of the region showing the areas where the virus is most rampant. The CDC also has updated its travel and testing guidance for all of Miami-Dade County.

Yellow shading on the map designates cautionary areas where local transmission has been identified but evidence is lacking that transmission has reached a critical level. Red shading shows places where local, state and CDC officials have determined that the intensity of transmission of the virus presents a significant risk to pregnant women, based on factors such as geographic distribution of cases, number of cases identified, known or suspected links between cases, and population density. 

Currently, red areas include a 4.5-square-mile section of Miami Beach and a one square mile of Little River in Miami-Dade County. The rest of Miami-Dade County is shaded yellow.
