helloo! good day. im 20m and i got tested as positive for covid19 declared asymptomatic but i could say that im not cause i felt slight headaches at the back of my head but i think its because of stress being jealous in my friends for playing our sports, and backpains which i presume that its because of being in bed most of the day. now im on my 16th day. i feel like going to cough but not, my throat is not a itchy, i just feel discomfort inside my mouth and congestion since i got swabbed which comes on and off sometimes( my dad said the swab got a blood after) and my question is can i go out in my 20th day and cant infect someone?
