When citizens get sick you can hire new ones until the population exceeds the limit
What happens is that you get sick citizens, and I believe that they are then not included in the total population count. Because of this, you are able to recruit new citizens until your population goes over the limit, allowing you more citizens than the housing you have. As you can see in the picture, I currently have more citizens than allowed, as a direct result of recruiting more, and then sick citizens recovering.
