what kind of rash is this? mosquito bite or something serious? it has appeared on chin,arms and hand. my son is 1.5 years old. please say

A. Okay so the weight is patchy it is not looking like a mosquito bite as you’re mentioning that it is at different places I believe it could be outbreak in the skin it could probably be a small box or something maybe but you’ll have to have an assessment with your pediatrics to have clarity and treatment on that
