Sickness

Villagers in, Animal Crossing: Wild World, Animal Crossing: City Folk and Animal Crossing: New Leaf can become sick, which causes them to shiver (and sometimes show the 'depressed' emotion) and stay in their houses. Villagers can gradually be recovered from being sick if they are given medicine from Tom Nook's shop or the Nookling Stores once a day. Sickness usually lasts for three days if medicine is given every day, but this can vary slightly. While villagers are sick, they will not react positively and will ask for medicine. Selecting the medicine will not give a positive response if the player has no medicine in the pockets but will open the pockets if he or she does. After receiving medicine, the villager will usually remark on how bad it tasted, but will thank the player. Once the sickness has passed, the villager will give the player an item the following day (or in a letter) if the player took care of the villager while he or she was sick.

In, villagers may inform the player if another villager is sick.

Sick villagers will appear in 's hospital after the player designs this facility.

In, villagers cannot become sick. The feature was phased out due to a bug with the system where a villager may move away without pinging the player, as being sick interfered with pinging.
