Check for small red bumps, blisters, or pimple-like rash
Look for burrow lines in skin, especially between fingers, wrists, elbows, waist, buttocks, and genitals
Inspect household members or close contacts for similar itching or rash
See a healthcare professional for a skin examination
Use dermoscopy if available to look for mites or burrows
