Can’t you just stay home if you are sick with a vaccine-preventable disease and avoid getting others sick?
Incubation Period of Diseases
The problem with that idea is that the incubation period for some diseases is very long.
The incubation period is defined as:
The time from contact with infectious agents (bacteria or viruses) to onset of disease.
- the incubation period for chicken pox is 10 to 21 days, meaning that it can take 10 to 21 days for you to get sick after being exposed to someone with chicken pox or shingles
- you can be contagious to others one to two days before you even develop the classic chicken pox rash
While that might not be too big a deal if everyone around you is completely vaccinated, if any contacts are too young to have had two doses of the chicken pox vaccine, can’t be vaccinated because they have an immune system problem, or had their immunity wear off because of an immune system problem, then they could get sick.
What about COVID-19?
“The incubation period for COVID-19 is thought to extend to 14 days, with a median time of 4-5 days from exposure to symptoms onset. One study reported that 97.5% of persons with COVID-19 who develop symptoms will do so within 11.5 days of SARS-CoV-2 infection.”Interim Clinical Guidance for Management of Patients with Confirmed Coronavirus Disease (COVID-19)
The incubation period for COVID-19 is 14 days.
That’s why the incubation period often turns into the quarantine period for most vaccine-preventable diseases.
