Which cities were part of the Malaria Belt in Florida during the early 1900s?

During the early 1900s, the Malaria Belt in Florida primarily included areas along the state’s coast and in the northern regions where environmental conditions facilitated the spread of malaria. Mosquitoes, particularly the Anopheles species, thrived in the warm and humid climates typical of these areas, allowing malaria to spread among the population.

The correct choice accurately reflects cities that were significantly affected by malaria during that time period. Pensacola, Jacksonville, Tallahassee, and St. Augustine were all prominent locations where malaria was prevalent. Historical records indicate that these cities had a higher incidence of malaria cases due to their geographic and climatic conditions which favored mosquito breeding.

The other options contained cities that were either less impacted by malaria or were not significant areas of concern during that period. Understanding the geographic distribution of malaria in early 20th-century Florida is critical for grasping the public health challenges of that era and the measures that were implemented to combat mosquito-borne diseases.
