Educate students to avoid any domestic or wild animal that is acting strangely, is sick, or is unfamiliar to them
Teach students to report any contact with a wild animal or an unfamiliar domestic animal, and to report any bites or scratches from any animal
If a bite or scratch occurs:
- Provide first aid to the child; flush the wound with lots of water; clean the wound with soap and water, then rinse it well; refer for medical treatment by or under the direction of a physician
- If you can, confine the animal; if not, note the size, appearance, and any distinguishing characteristics of the animal. If available, write down the name, phone number and address of the owner and the events surrounding the bite. If the animal escapes, it is particularly important to get as much information as possible
- Report the bite to the local health department and animal control
*Exclusion criteria are not all inclusive. Students or staff may need to be excluded from group setting such as classroom or extra-curricular events if other exclusion criteria are present, such as individual is unable to participate comfortably in program activities, illness calls for greater care than staff can provide without compromising the health and safety of other children, there is a risk of spread of a harmful disease to others, or the presence of fever, lethargy, persistent crying, difficulty breathing, or other signs of illness. Schools and daycare facilities should have policies in place to address illness exclusion.
School and Daycare staff with concerns or questions about communicable diseases should contact the local health department for guidance.
Tips For Keeping Healthy
Hand washing is the single most important way to prevent the spread of communicable diseases
Use soap, warm water and disposable paper towels and wash your hands frequently. Teach children to wash their hands, too. Hand washing reduces the number of microorganisms on hands that can spread communicable diseases. It is recommended that:
- Hands be washed when arriving for the day and leaving for the day and when moving between groups of children, and as follows:
- Before and after eating or handling food, feeding a child, administering medication, or playing in water used by more than one person
- Before and after eating or handling food, feeding a child, administering medication, or playing in water used by more than one person
- After diapering or using the toilet; handling any bodily fluid, uncooked food, or animals; cleaning cages/litterbox; being outdoors, playing in sandboxes or at playgrounds; and/or cleaning or handling trash/garbage.
Open the window to let the fresh air in
Well-ventilated rooms help reduce the numbers of airborne germs inside. Airing out the rooms is important, even in the winter. Respiratory diseases easily spread from coughs and sneezes. Opening the window at least once a day lets the germs out and fresh air in.
Follow a good cleaning schedule and sanitize or disinfect in the proper way
- Guidance on cleaning and disinfection in schools is available at http://www.cdc.gov/flu/school/cleaning.htm.
- Consider utilizing a chart to ensure all areas are addressed for cleaning, identifying the appropriate sanitizing or disinfection method, and according to schedule.
- Increase frequency of cleaning and disinfection during illness outbreaks, when there is known contamination, when there is visible soil, blood, or bodily fluids, or when recommended by the local health department.
- Remember, a surface must first be clean for a sanitizer or disinfectant to be effective. Follow product label instructions for use.
Require that children are up to date on immunizations
An immunization schedule is available at https://www.cdc.gov/vaccines/schedules/. Check immunization records and update them regularly. When parents have questions or concerns about immunization safety, provide them with science-based educational materials available at CDC: http://www.cdc.gov/vaccines/parents/index.html and the Immunization Action Coalition at http://immunize.org/talking-about-vaccines/.
Do not share personal items among children and keep their belongings separate
Do not allow children to share belongings such as hair brushes, food, drinks, clothing, hats, pacifiers or other items; separate children's coats, hats, and bedding items.
Separate children by using space wisely
- Maintain distance between sleeping areas, mats, cribs or cots.
- Keep children in groups and consistently assign caregivers to the same group.
- Keep diapered and toilet-trained children separate to prevent spread of diarrheal diseases.
- When possible, staff responsible for food handling should not be involved in diaper changing, or at a minimum, should not perform diapering during times of food preparation and handling.
Exclude sick children and staff
Ensure that parents receive information on when to keep ill children at home and other school exclusion policies, sending a sick child home with his/her parent helps to prevent the other children from becoming ill with a communicable disease.
