I'm no virologist but in my mind I dont understand how quarantining a city will address the problem with the outbreak.

The whole outbreak started with one person of course. with it infecting a whole city even if the outbreak is entirely limited to that city how will quarantining help long term. Eventually they need to remove the quarantine and vaccines are years away. When they eventually do if even one person has the disease still then it will just start al. over again.

Obviously it makes sense to qtine individuals who traveled from an effected area for a set number of days to see if they are carrying the disease before releasing them. That sort of quarantine makes sense. But a whole city, not sure how that will help.

@freemo I think the idea is if we know that the incubation period is, say, 2 weeks and the patient is no longer infectious after, say, 5 weeks.

You close off a population and wait 2 weeks, if no one shows any new symptoms you only have the currently infected left.

Wait another 5 weeks, and if no one is still ill, and no one is showing symptoms, you can be fairly confident that the disease will have died out in that population

@M0YNG Yea but when we talk about large populations thats not how it works. The cat is out of the bag so to speak. Quarantining large areas never work because there will literally never be a point in the future (unless a vaccine is created) where the infected rate will reach 0.

Quantines work and are logically with individuals and small groups because in those settings you expect infection rates to reach 0. In larger populations that will never happen however so it isnt effective.
