Don't Let Salmonella Ruffle Your Feathers
Partial Case Overview
In early 2014, epidemiologists identified five clusters of human Salmonella infections using PulseNet. PulseNet is an online surveillance system that compares the DNA fingerprints of bacteria from people around the United to States to find clusters of disease that might represent unrecognized outbreaks.
Many ill persons in each of the five clusters reported contact with live poultry, primarily chicks and ducklings. Since the poultry was from the same mail-order hatchery, the epidemiologists decided to merge the clusters into a single investigation.
During February 3–October 14, 2014, a total of 363 persons infected with outbreak strains of Salmonella serotypes Infantis, Newport, and Hadar were reported from 43 states and Puerto Rico, making it the largest live poultry-associated salmonellosis outbreak reported in the United States.1,2
At the end of this case study, students will be able to
construct a definition of a zoonotic disease;
use epidemiology to hypothesize the origin of the outbreak;
create a spot map to identify patterns that characterize an outbreak by geographic location; and
develop prevention strategies based on the One Health approach.
Salmonella Scare
During February 3–October 14, 2014, a total of 363 persons infected with outbreak strains of Salmonella Infantis, Salmonella Newport, or Salmonella Hadar were reported from 43 states and Puerto Rico. No deaths were reported, but 33% of infected persons were hospitalized. Number of cases by state are provided in Table 1.
Graded Assignment:
On Google Classroom you will see you assignments; one will be a map to color on Google Drawing and the other will be a form.
The map will be a graded assignment, the form will be participation. :)
