It could be days before they can rescue you and your family. Some of the same techniques used in wilderness survival shelters, can be implemented in an urban emergency shelter.

In brief: Depends on severity. A tiny pimple or pustule on the skin, caused by regular staph, should heal up in 3-5 days after the pus comes out.

People who have internal abscesses in their bodies, or have suppressed immune systems, can take several weeks of treatment with IV antibiotics (even longer in bone infections).
