...I have been exposed several times by different groups of relatives. Some of whom were around Christmas and others that were around New Years and possibly afterwards.
...in my experience with the common cold or the flu it takes different people different amounts of time to get over them depending on their immune system and general health or the severity of the infection. Most Doctors will tell ya "A week or ten days". A quarantine of any specific length can vary with these factors. The five day or ten day or two week quarantine being an approximation.
...not certain at this time that I have covid. It's kinda like when ya feel rough and think ya might be coming down with a cold by ya ain't sure if it's that or allergies or what.
