The US Centers for Disease Control and Prevention has released a summary of notifiable diseases in the US for the year 2011. These statistics are collected and compiled from reports sent by state health departments and territories to the National Notifiable Diseases Surveillance System (NNDSS).
According to the CDC, a notifiable disease is one for which regular, frequent, and timely information regarding individual cases is considered necessary for the prevention and control of the disease. The list of nationally notifiable infectious diseases is dynamic, as new diseases are added and others deleted as incidence declines.
I used data from this report to compile a list of the top ten notifiable diseases for 2011 (numbers of cases in parentheses):
Here are the top ten notifiable viral diseases:
Notably absent from the list is influenza, which is not a notifiable disease. Some other notifiable diseases which were not reported in the US in 2011 include poliomyelitis, SARS, and St. Louis encephalitis virus disease.
The report is recommended reading because it summarizes the data in many other ways, including (for example) by state, region, month, and age group.
*Six of the rabies cases were in humans, the remainder in other animals.
