When People Got Sick

Posted December 22, 2021

This chart shows the month when 10 people in this Listeria outbreak got sick.

Recent illnesses may not be reported as it usually takes 3 to 4 weeks to determine if a sick person is part of an outbreak. The true number of sick people in an outbreak is also likely much higher than the number reported. This is because many people recover without medical care and are not tested for Listeria.
