Hello everyone. I'm writing at 3 am because I got the PCR result - positive. I think it's a new strain, as my back was aching terribly, exactly like during seizures - point by point. Temperature 39.3, headache, dry cough and phlegm, all in one evening appeared. I'm not afraid for myself, I brought down the temperature, the back doesn't hurt anymore, only dry cough. I'm scared for my daughter. She is half a year old, how can I make sure she doesn't get sick? She has no symptoms.
