My 4 yr old niece contracted covid from a family friend that decided to come and visit my sister's kids when my sister was out of town. The friend and her husband hadn't been practicing social distancing and ended up coming down with Covid-19. She was infected when she was visiting my niece and nephew but didn't know she was sick. Thankfully my nephew didn't get sick and my niece was only hit with mild symptoms of a fever but didn't get any respiratory issues. Her pediatrician has advised my sister to keep an eye on her for any secondary health issues just in case she ends up developing any other complications.
