Will my mom [55F] be ok? She can’t smell and has all these covid symptoms but the results are taking forever.

Hey guys,I can’t help but to worry about my mom. I spoke on the phone with her earlier today and she’s been feeling sick for the past few days. She’s got a cough, can’t smell, and is feeling weak. My brother [29M] lives with her too and is starting to feel weak with a fever. I’m like 90% sure it’s covid. She doesn’t have any crazy pre-existing conditions. She’s just slightly overweight (5’0” and 140 lbs?) and I think hypothyroidism(?). Will she be okay? I know the mortality rate is low but I can’t help but to worry if she’ll become another statistic in all this.Thanks.
