Final answer:
Aiden would most likely reach out to the Centers for Disease Control and Prevention (CDC) to find information on the prevalence of measles cases and the number of deaths from the disease.
Step-by-step explanation:
In order to find information on the prevalence of measles cases and the number of deaths from the disease, Aiden would most likely reach out to the Centers for Disease Control and Prevention (CDC).
The CDC is the main national public health agency in the United States and is responsible for promoting and protecting public health. It receives reports on infectious diseases, including measles, from regions in the United States and its territories. These reports are compiled into a searchable database called the National Notifiable Diseases Surveillance System (NNDSS) and published in the Morbidity and Mortality Weekly Report (MMWR).
By contacting the CDC, Aiden can access accurate and comprehensive data on measles cases and deaths, which will help him in his research as a statistician.
