Worried 😟 Help!!!!

My baby has 2-3 mosquito bites.. I’m afraid she will get sick.. what can I do?!! I get bitten all the time..I didn’t think much of it.. but my co worker scared me.. she said .. oh you have to look out for symptoms.. there’s the west Nile.. now I’m really scared 😱

Hopefully this protects my little one at night.🙏🙏
