John Greenleaf Whittier Elementary School

Kids at John Greenleaf Whittier Elementary School spend the day in one room with the same classmates, so a single bug usually shows up as a cluster in one grade before it reaches the rest of the school. Watching what parents in your child's grade are logging is the earliest signal you get.

• Strep throat and scarlet fever cluster by classroom and need a swab to confirm
• Stomach bugs and norovirus move through lunchrooms and shared bathrooms
• Head lice peak right after breaks when hats and coats pile together
• Flu and COVID-19 arrive later in the fall and spread school-wide, not grade by grade

Every school sets its own sick policy, so check yours first. These are the rules of thumb most schools and daycares follow:

• Fever-free for a full 24 hours without fever medicine before returning
• No vomiting or diarrhea for 24 hours, and eating normally again
• On antibiotics for at least 12 to 24 hours for strep throat or impetigo
• Eye discharge cleared, or cleared by your pediatrician, for pinkeye
• Well enough to take part in a normal school day, not just well enough to sit through it
