Illness



With the infamous guinea pig disease now a thing of The Sims past, Sims can now catch a few different diseases, each with their own symptoms and method of catching - they're contagious, too.

Morning sickness
Morning sickness almost* always happens when a Sim is pregnant and in the first trimester. It also has the same symptoms as food poisoning. If the Sim is a female and she didn't plan for a baby, or if it's a male Sim and he wasn't recently abducted, then it is most likely he/she just ate some spoiled grub.

The only way guaranteed to prevent a Sim from getting morning sickness is to download a mod that will stop it from happening. Otherwise its intensity varies Sim to Sim.

Food poisoning
There is a 5% chance any time a Sim eats spoiled or burnt food that the Sim will get food poisoning. Sims will suffer nausea (a sharp drop in comfort) diarrhea(a sharp drop in bladder) and will run to the toilet at regular intervals. In The Sims 3, a Sim who ate spoiled or burnt food will result the nauseous moodlet and they will throw up after 2 hours.

Cold
There is a 5% any time a Sim goes to work or school that the Sim will catch a cold. Pretty obviously Sims will suffer from coughing and sneezing fits causing a drop in comfort.

Flu
There is a chance that a Sim, in the presence of cockroaches, will catch the flu. The flu has all the symptoms of a cold with sharp drops in fun and energy as well. When you first play the Beaker household in Strangetown, there will be cockroaches near the refrigerator. Both Loki and Nervous will go to stomp on them and will catch the flu. It is best to cancel out this action before they stomp on them.

Pneumonia
If the cold is not cured quickly it can turn into pneumonia. The pneumonia has all the symptoms of both the cold and the flu, as well as sharp and sudden drops in energy in which a Sim appears to nearly pass out. If energy drops low enough, the Sim really will pass out.

The Sims infected could die if not treated!

Mysterious disease
Sims can be infected with this when using the biotech station. The symptoms are random, and can be any of the above. It should be noted that this disease is highly contagious and can easily spread through the entire neighborhood in a matter of days.

Curing
The best cure for all illnesses is rest. Keep the ill Sim away from healthy Sims, and make them relax for the period of their illness, until a message appears saying they are cured.

Medicine
The medicine made with the biotech station cuts down the resting time needed to be cured of a sickness.

Orange juice
If The Sims 2: Seasons is installed, drinking orange juice made from Tasty or Mouthwatering fruit will cure colds.

Grandma's Comfort Soup
With The Sims 2: FreeTime installed a Sims with the Family aspiration, they can achieve the aspiration benefit. "Grandma's Comfort Soup". When eaten, it will cure any disease a Sim has. It is recommended to have AT LEAST one Family Sim in the household, whether it be the mom, butler (controllable), or Grandma, just in case one Sim has the "Unknown Virus" or any other small illness.

Grandma's Comfort Soup is the first reward so it is available to Sims with "Family" as a primary or secondary aspiration.

Passing it on
Not all illnesses are contagious and those that are become contagious at different rates. As food poisoning is an infection from only one source and morning sickness only affects pregnant Sims these are not contagious. The mysterious disease is more contagious than the flu and the flu is more contagious than the cold.

Death
If the flu, pneumonia, or a mysterious disease is not cured quickly enough, the Sim will die from illness (Children are taken away by a Social Worker before they get a chance to die). Toddlers and babies cannot get ill. The mysterious disease can kill a Sim in under 24 Sim hours (So it's possible for a child to die of the mysterious disease).

Morning sickness
Morning sickness always happens when a Sim is pregnant and in the first trimester. Sims get the Nauseous moodlet and eventually they vomit.

Food poisoning
When a Sim eats spoiled food they will develop the Nauseous moodlet and eventually vomit.

Tiberium poisoning
Keeping Tiberium in a Sim's inventory for a while will give them the Nauseous moodlet and cut their mood down.
