Overview
Zois can get sick from weather exposure, contagion, and seasonal allergies. Illness causes visible symptoms (coughing, sneezing), mood penalties, and reduced effectiveness at work and school. If left untreated, illness can progress into an infection and become fatal. Treatment is handled through First Aid Kits placed in the home or, for a permanent solution, the Immunity Donut from the Meow Store.
Causes of Illness
Cause | Details |
|---|---|
Cold weather | Wearing light clothing during winter or in cold conditions. Dowon's four seasons make this a recurring risk. |
Rain exposure | Standing outside during rain. The v0.6.0 update increased the time before catching a cold in rain from 1 hour to 6 in-game hours. |
Contagion | Illness spreads within households. If one Zoi gets sick, other household members are likely to catch it quickly. |
Pollen allergies | Seasonal. Triggers the "itchy nose from pollen" uncomfortable emotion. Separate from cold/flu. |
Bliss Bay and Cahaya stay warm year-round, making cold-weather illness rare there. Dowon has four distinct seasons and is where most weather-related illness occurs.
Symptoms
A sick Zoi shows several visible and gameplay effects:
Sneezing and coughing animations. Nearby Zois react with visible disgust.
The Uncomfortable or Miserable emotion replaces the normal mood state.
Reduced Energy regeneration.
Slower skill learning rates.
Reduced social interaction effectiveness.
Lower performance at school and work.
Treatment
First Aid Kit
The First Aid Kit costs 100 Mew and is purchased through Build Mode under Furniture > Props (or search "First Aid Kit"). Place it in the home, then click it as the sick Zoi. Two medicine options are available:
Medicine | Treats |
|---|---|
Take Cold Medicine | Colds and flu from weather/rain/contagion. |
Take Allergy Medicine | Pollen allergies. |
First Aid Kits contain unlimited medicine and never run out. The Zoi will "sparkle and light up" to indicate recovery has begun. A short rest period completes the healing. Most premade houses and apartments already have a First Aid Kit placed in them, so check before buying a new one.
Immunity Donut
The Immunity Donut (sometimes called the Vaccine Donut) is available in the Meow Store for 100 Meow Coins. Access it through the Zoi's portrait card in the lower right corner, then click the "Meow-Shop" button. The Immunity Donut grants permanent immunity to both colds and allergies for the rest of that Zoi's life. It is a one-time consumable per Zoi.
Death from Illness
If a Zoi's illness is left untreated for an extended period, it can worsen into an infection and become fatal. This is one of the death types in the game. Rest and relaxation alone do not cure illness; only the First Aid Kit or Immunity Donut work as treatments.
Hospitals
There are no functional hospitals in the current Early Access version. When a Zoi is sick, the game may display a message referencing the "Dowon Medical Station," but this location does not exist on the map. All illness treatment is done at home through the First Aid Kit. The 2026 roadmap mentions expanded healthcare systems as a planned addition.
Prevention
Dress Zois appropriately for the weather. Warm clothing in winter, light clothing in summer.
Check the weather forecast on the smartphone before heading out.
In Dowon, rotate wardrobes with the seasons. The four-season climate makes temperature management an ongoing concern.
Keep a First Aid Kit at home at all times. They're cheap (100 Mew) and unlimited use.
If one household member gets sick, treat them immediately to prevent it spreading to everyone else.
For a permanent solution, spend 100 Meow Coins on the Immunity Donut from the Meow Store.
