DIARRHEA (Infectious Diarrhea)
Diarrhea is defined as: 1) an increase in the
number of stools over what is normal for that
person, and 2) stools which are not formed (i.e.,
loose and watery and take the shape of the
container they are in). (NOTE: Breas t-fed babies
may have stools that are normally
not formed).
There are two (2) general types of diarrhea:
infectious and non-infectious.
Infectious Diarrhea is caused by a virus,
parasite, or bacterium. It can spread quickly from
person-to-person, espec ially in daycare centers.
Some of the causes of infectious diarrhea, such as
Campylobacteriosis, shiga -toxin producing E.
coli, giardiasis, salmonellosis and shigellosis, are
discussed in their own fact sheets found in this
document. There are other agents that can also
cause infectious diarrhea in children. These
include parasites (e.g., cryptosporidiosis, amoeba)
other bacterial (e.g., yersinia) and other viruses
(e.g., Rotavirus). Although these other disease -
causing organisms are not discussed in de tail, the
general principles outlined in this section are
applicable to prevent the spread of any of these
germs.
Non-infectious Diarrhea can be caused by toxins
(e.g., certain types of food poisoning), chronic
diseases (e.g., cystic fibrosis) or antibiot ics (e.g.,
ampicillin). Non -infectious diarrhea DOES NOT
spread from person-to-person.
Who gets it?
Anyone can catch infectious diarrhea. It can
spread especially quickly among babies and
young children who are not toilet -trained or who
may not wash the ir hands well after going to the
bathroom. It can also easily spread to the adults
taking care of them and helping them with
diapering and toileting.
How is it spread?
The germs that can cause infectious diarrhea are
spread by fecal-oral route.
How is it diagnosed and treated?
The germs can be diagnosed by stool cultures or
by looking at stool under a microscope for eggs or
parasites. (The healthcare provider will ask for a
stool sample and send it to a laboratory for
analysis). The physician will deci de on
appropriate treatment.
How can the spread of diarrhea be
prevented?
Hand washing is the most important way to stop
the spread. Specific methods for preventing the
spread of infectious diarrhea are discussed in each
fact sheet.
Who should be excluded?
Any person with diarrhea shall be excluded from
food handling, from childcare agencies and from
direct care of hospitalized or institutionalized
patients until 48 hours after resolution of
symptoms.. Children who have 2 or more stools
above their normal amount should be excluded as
it impedes the caregiver’s ability to care for the
children and maintain sanitary conditions. For
diarrhea caused by a specific agent, see the related
fact sheet to learn if exclusion is necessary.
Reportable?
Non-specific diarrhea is not reportable. Clusters
of diarrhea illness in a facility should be reported
to the Division of Public Health Services, Bureau
of Infectious Disease and Control at (603) 271-
4496.
