Covid 19 a important doubt. Vitamin c.

It was on 27 eve my dad had a high fever of 101 and he tested positive for covid-19 and he was with us on Saturday and Sunday he left to out station on Monday morning and there he had the fever . So he was in contact with us for the past 2 days with no symptoms . And today it's been 11 days of him tested positive and he is in hospital under treatment . Whereas me my mom and my sister have no symptoms so far and we are under home quarantine . So my doubt now is . Are we all asymptomatic or we didn't contract the virus or our symptoms are yet to start or can we end our quarantine in next 3 days and lead a normal life . And we are taking vitamin and some supplements and I have mentioned it and I'll do again we took arsenic album 30 for 3 days in empty stomach and we stopped now for the past 11 days we are taking zinc acetate 50 mg ,vitamin d3 2000iu, vitamin c .
