Tests indicated that they all had become infected with salmonella.
Salmonella are bacteria that are usually transmitted through foods such
as contaminated meat or eggs.
How did these children become infected with salmonella?
To find the answer, Colorado health officials called in Dr. Cindy
Friedman. Dr. Friedman works at the Centers for Disease Control and
Prevention (
down
the
CDC), a United States government agency that tracks
and studies the transmission of diseases throughout
world.
Cindy Friedman studies outbreaks of diseases
in groups of people rather than in individuals. *
Her specialty is infectious diseases, illnesses that
spread from person to person. She has investigated
outbreaks of disease in such places as rural Bolivia
in South America, Cape Verde Islands off the coast
of Africa, and a Vermont farm.
