Needs to see the doctor or asthma nurse to review treatment. 

ConjunctivitisWith yellow or green pus (Red Eyes) 

May return 24 hours after treatment started 

Chicken Pox 

Some children have a fever, abdominal pain, sore throat, headache, or a vague sick feeling a day or two before the rash appears 

Return when the blisters are all dry and crusted over 

Hand, foot and mouth disease Not infectious once rash appears 

No need to stay home unless drooling 


Patch of red, itchy skin. Blisters develop on this area, soon

forming crusty, yellow-brown sores 

May return 24 hours after starting antibiotic medicine, 48 hours after starting antibiotic cream. Sores must be covered with dressing. 


Ring Shaped or oval patch of scaly red skin 

Return once started on treatment. Keep area covered. 

Head Lice 

Spread directly from head to head so short and tidy hair may help 

They are a nuisance, not a reason to stay home. 

Doctor or dentist


Back to school afterward unless

the dentist or doctor says stay at home.
