These rashes have both flat (macules) and raised (papules) areas. They're common in viral infections like measles and rubella. The rash usually starts on the face and spreads downward. It may be itchy and can last several days.
Vesicular Rashes
Vesicular rashes have small, fluid-filled blisters. Chickenpox is a classic example. These blisters often start on the trunk and spread outward. They can be very itchy and may leave scars if scratched.
Petechial Rashes
Petechiae are tiny, round, purple-red spots that don't blanch when pressed. They're caused by bleeding under the skin. While they can be harmless, they can also signal serious conditions like meningococcal disease or blood disorders. Always get these checked by a doctor.
