The virus takes time to show up in the reports. My dad had COVID and I was living with him under the same roof, sharing the same table and toilet etc for almost a week until I started getting symptoms too. On the third day after I started developing symptoms, We did tests together and my dad’s result came back positive whereas my came out negative. However the doctor said that I have COVID too and if I get tested after a week I’ll be positive too. They should really consider rescheduling the game since they might be unknowingly spreading due to a false negative result.
