Girls, can you please tell me if you've had something like this with your kids? We have diarrhea for 3-5 days straight, but three times we also have vomiting. As I am in Moldova, I went to the hospital and they told me to call an ambulance at home. They came, took our test for COVID (thank God negative), said it could be on the teeth. The temperature is above 37.8 and doesn't rise. The ambulance took us to the hospital, where they prescribed us water and Linctus tablets. I'm very worried about the little one, if it gets worse, I will go to Odessa to see our doctor. Just maybe it could be on the teeth.
