The “quarantine of susceptible contacts without presumptive evidence of immunity” is a key tool that health experts use to control outbreaks of vaccine-preventable diseases.
Some examples of quarantine periods include:
- 10 days for healthy dogs and cats after a bite (rabies)
- 21 days for measles
- 21 days for chicken pox
In addition to susceptible contacts, during an outbreak, even those who aren’t contacts are sometimes put under quarantine, or at least restricted from going to school, if they aren’t naturally immune and haven’t been vaccinated.
This is especially common during outbreaks of measles and chicken pox and in which case the quarantine may last much longer than 21 days. In general, unvaccinated kids will have to stay out of school for at least 21 days after the last person was no longer contagious.
