Information for Schools (and Child Care Providers)
Hand, Foot, and Mouth Disease
Orange County Public Health has had multiple reports of clusters of hand, foot, and mouth (HFM) disease in Orange County schools. HFM is caused by enterovirus, a common virus that most children are exposed to in childhood. HFM infection is characterized by a rash on the hands, feet and inside of the mouth. Fever and sore throat often accompany the rash. Almost all HFM infection in children are mild, though severe illness is seen occasionally. The most important treatment is assuring that an infected child does not become dehydrated. For more information, please visit http://www.cdc.gov/hand-foot-mouth/. Schools with multiple cases can utilize this letter
All suspect and confirmed pertussis cases are reportable to the health department within one (1) working day. Even during an outbreak, complete information on each individual case must be reported.
*High risk conditions for pertussis include infants less than one year of age, pregnant women, persons with chronic lung conditions (including asthma) or immunocompromise, un- and under-vaccinated persons, household contacts of infants or pregnant women in the third trimester, childcare providers, and persons who work with infants or pregnant/postpartum women.

Individual cases of chickenpox are not reportable unless the case is hospitalized or dies.
*High risk conditions for chickenpox include immunocompromise and pregnancy.
Recommendations for Schools with Suspect or Confirmed Chickenpox Cases: The identification of a single case of varicella should trigger intervention measures to prevent an outbreak. If still infectious, the case should be excluded or isolated from the school immediately. Next, a notification letter can be sent to those that may have been exposed to the case. The letter could be sent home with the children in the same classroom as the case. However, how broadly to distribute the notification letter for a single case may vary depending on the specific situation.
For schools with ≥3 chickenpox cases in 2 months, call HCA Epidemiology at 714-834-8180 and ask to speak to a PHN.

Reporting of increased absenteeism, outbreaks or clusters at K-12 schools
Note: this mechanism of reporting is for increased absenteeism, outbreaks or clusters due to non-specific respiratory, influenza-like illnesses (ILI), or gastrointestinal (GI) illnesses. It is NOT to be used for diseases that are reportable as individual cases (e.g., pertussis, meningitis). These reportable diseases should be reported to Epidemiology as required using the methods and time frames specified on the reportable disease list. To report suspect chickenpox illnesses, see above under Chickenpox. For all other outbreaks or clusters, call Epidemiology at 714-834-8180.
Please call Epidemiology immediately at 714-834-8180 if a large number of students in affected classroom(s) or other exposed group(s) are high risk students. In general, high risk conditions include immunocompromise and pregnancy but may also include other underlying diseases. See specific illnesses (e.g., influenza) for a list of high risk conditions by illness type.*
Please use the following criteria to report respiratory or gastrointestinal (GI) illnesses:
At least 10% of average daily attendance is absent, OR
20% of classroom or group ill with similar symptoms, with a minimum of 5 ill.
(Example of increase in absenteeism: Average daily attendance may already be calculated for your school. If not, you can approximate on your own for reporting increases. For school with 1000 kids; if absenteeism is usually 15%, or 150 absent each day, baseline attendance would be 850 (1000 minus 150). An additional 10% of 850, or 85 students, would need to be absent to meet this increase in absenteeism criteria).
To report unusual absenteeism or increase in respiratory or GI illness OR to report clusters of respiratory or GI illness, complete the following:
Weekly Updates (PDF Form; Word Form) to monitor activity until back to baseline for one week
*If unable to complete on-line, please print and fax Intake Form (PDF Form; Word Form) for initial notification (both increased absenteeism or clusters) to 714-834-8196.
Please notify Epidemiology immediately by phone at 714-834-8180 of any hospitalizations or deaths.
