Determining the Incubation Period

WHO worked with an international network of statisticians and mathematical modellers to estimate key epidemiological parameters of COVID-19, such as the incubation period (the time between infection and onset of symptoms). 

• Preliminary estimates of median incubation period are 5-6 days (ranging from 0-14 days).
• By March 6, 2020, the WHO settled on incubation period of up to 14 days [2]. 

With the new concept of asymptomatic spread, an incubation period gives cause to isolate a PCR positive test case for the WHO declared maximum duration of 14 days.  Meaning it could be 14 days before the onset of symptoms!  That person may never produce symptoms!  Historically a disease meant “dis-ease”, not well, having a symptom. 

From 2020 anyone off the street can get diagnosed with COVID-19 disease if they return a positive PCR test, the lab runs the cycles of amplification up to 40 cycles (or 45) , which as Kary Mullis cautioned, you’re sure to find “something” its that good!
