Note: For outbreaks in closed communities, such as residential aged care facilities, all residents and staff who have had contact with residents with scabies require treatment. Quarantine the affected area if possible. If staff from the affected area have worked elsewhere, that area should also be assessed. The source of a scabies outbreak in a residential aged care facility should be identified because the patient may have crusted scabies. If a school-aged child has scabies, notify the school. Treatment of children who do not have scabies is not required. Children with scabies can return to school when two treatments for scabies, 1 week apart, are completed. |

Notification | Not required |
