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 always happens when your Sim is pregnant and in the first trimester. It also has the same symptoms as food poisoning. If your 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.

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.

Cold
A 30% chance when standing next to or near Cockroaches or any time a Sim goes to work, school etc. Pretty obviously Sims will suffer from coughing and sneezing fits causing a drop in comfort.

Flu
If the cold is not cured in three days it can become the flu. The flu has all the symptoms of a cold with sharp drops in fun and energy as well.

Pneumonia
If the flu 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.

Seasons
If Seasons is installed, drinking orange juice made from Tasty or Mouthwatering fruit will cure colds.

FreeTime
If you have FreeTime installed on your computer and one of your Sims is a Family Sim, you can achieve "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.

If you do not wish to change a character's aspiration to "Family", you can use the Secondary Aspiration tool from Freetime, as Grandma's Comfort Soup is the first available reward. This way, you can have your Sims Aspiration, plus the added benefits of a Family Sim.

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 illness is not treated within ten Sim days, the Sim will die from illness (Child sims are taken away by a Social Worker before they get a chance to die). Toddlers and babies cannot get ill.

-In a test I ran, I found that a type of Mysterious disease killed a Sim in under 24 hours.
