Positive for covid

I noticed my husband felt kinda warm Saturday afternoon, he checked his temp and it was between 99-100. He said he felt fine, other than a headache. I told him he need to get checked for Covid so he went Sunday morning to be seen. His fever was gone and has been since then. The doctor said he didn't think it was Covid because his fever only lasted a day. They gave him a flu test, it was negative. They went ahead and gave him the Covid test too. He hasn't had any other symptoms, fever is still gone. The results was added to his labcorp portal and they were positive. I am completely freaking out! I'm so scared I may get it or our 9 year old daughter will get it. So so so scared right now y'all. A friend of mine said her son stayed last weekend with her mom and they had lunch Sunday together and her mom tested positive and my friend and her son didn't catch it so that gives me a little hope. My anxiety is extremely high because of this.
