A community health nurse investigates an outbreak of pinworm at a local daycare center. To minimize the spread of infection, which of the following suggestions would the nurse provide to the daycare workers?

A. No action is necessary because it is easily treated with oral vermicides: While treatment is simple, prevention through hygiene is still essential, especially in group settings. B. Every child in the daycare should be treated because they are all probably infected: Treatment should be based on diagnosis or close contact, not blanket treatment without evaluation. C. Using good hand washing is important to prevent the transmission: Pinworms spread via the fecal-oral route. Hand hygiene is the most effective way to prevent reinfection and spread. D. Close the daycare until all surfaces are cleaned: This is extreme and unnecessary - proper hygiene and targeted treatment are typically sufficient.
