Some sites (e.g., WebMD, Seattle Children's Hospital) claim that ringworm will stop being contagious after 48 hours of applying a fungicide cream, and then should clear up after 3-4 weeks.
Is this 48 hours rule of thumb mostly factual? I have a ringworm infection and put on clotrimazole cream, but am afraid to reinfect myself, or spread it to family members.
