Rashes

My marissa suddenly developed rashes!!realized it while bathing her yesterday..she has no fever so unlikely measles but what else could it be?allergic reaction?but to what?
Initially i want to bring her to the clinic today but the rashes nampak kurang a bit so tgk mcm mane this evening..mula2 mmg xnk g keje dh but my mom convinced me that shes going to b ok..furthermore pagi td bgn dah main2 dah so xpe la..tgk mcm mane nnt..
