Baby Rash

Please don't just view, I need answers pls

SlimBrawnie:
Last week, I started noticing something like mosquito bites on my hands, with the way it was increasing, I assumed it wasn't mosquitoes, maybe ants but then both my hubby & baby have not experienced it.
So I asked google, different things came up but I strongly suspected Chigger bites cos I had gone to my garden to get some scent leaves twice last week before these things started appearing & I only notice these bites when it starts itching me, it will be red with something like a white/yellow spot in the middle, then when it stops itching, it becomes black. It moved to my laps and then my stomach.
I discussed with a nurse friend, she said it could be measles or chicken pox, so I quickly went to the hospital and explained everything to the doc. He prescribed "Funbact A, Erythromycin 500mg, and predensol whatever" which I got from the hospital pharmacy. The next day which was yesterday, I noticed two bites on my bum and underneath my boobs. Those were the last major once that came up.
I completely forgot to ask the doc what the problem could be so I'd be careful. So pls I need someone to let me know what could be the problem so that if there are precautionary measures I'd need to put in place, I'd do so ASAP.
NB:Since I noticed the bites, I changed to dettol bath soap & religiously use salvon during bath time, yet it continued.
Thank you
