If your little people are constantly sick, one illness after another or have more than one illness at the same time, they may have an underlying infection. Infections MUST be diagnosed by using a Doctor Consultation, otherwise your little people will not get the correct medication, they will continue to get sick, and just like in real life, they may get everyone else in the home sick.

Some players choose to give strong infection fighting medications like Penicillin and Vancomycin without a Doctor Consult. That's not a good idea. Giving your little people medication that is not needed can adversely affect their health.
