Incubation period of covid19 is same for normal person and a person with copd ?

COVID-19 Incubation: On average, the time from exposure to symptom onset (known as the incubation period) is about five to six days. However, studies have shown that symptoms could appear as soon as three days after exposure to as long as 13 days later. These findings continue to support the CDC recommendation of self-quarantine and monitoring of symptoms for 14 days post exposure.

COVID 19: Average incubation period for COVID-19 is 2 to14 days (but as little as 1 day), median time is 4-5 days. You have more chance of having an accurate test result if you have symptoms or you wait at least a few days after COVID 19 contact. One study showed that people w shorter incubation sometimes have more severe illness. However, COPD is usually only a factor for severity if uncontrolled.
