[|Human|] My sister, my brother, and I all have developed a rash behind our ears, on our chests, and our backs. The rash looks like small red pimples and where as my sister s itched neither mine nor my brother s did. Neither of my parents got the rash but one of my sister s friend who spent the night the other day developed a similar rash as well.
[|AI|]  Hi, Welcome to Chat Doctor. Rash behind ear, Darters disease is a hereditary disease like that. It appears as skin color pa pule on upper trunk, neck, behind ear and groin. Skin rash aggravates during summer. They sometimes itch, and fine scale may develop at the top on lesion. When you remove this scale there will remain a pit like depression. A foul odor may develop from rashes. All that things may give you an unwashed look. But this type of rash is non-communicable so when it goes to your friend that might not darters disease. Seborreic dermatitis may be other possibility, if that you need to shampoo your head and neck with Mizoram/ disorder shampoo regularly for 10-15 minutes before bath. With regards.
