Detailed map of Symptoms, with Infectivity, Severity, and Lethality values added.
Symptoms can be evolved through the Symptoms screen. Evolving a Symptom costs DNA points, but each evolution will make your pathogen increasingly deadly, infectious or frightening.
There are 6 symptoms available immediately, the others must be evolved after you have evolved a symptom in contact with it. These symtoms are: Nausea, Coughing, Rash, Imsomnia, Cysts, Anaemia. The most deadly are Dysentery, Total Organ Failure, and Necrosis.
Certain Symptoms will create Symptom Combos, which generally increase disease effectivity.
| Name | Effect | Base Cost |
|---|---|---|
| Nausea | Irritated stomach lining leads to discomfort. Slight chance of infection when kissing | 2 DNA |
| Coughing | Chance of infection by spreading pathogen into surroundings, especially in high density, urban areas | 4 DNA |
| Rash | The skin becomes blistered and painful, slightly increasing infectivity | 3 DNA |
| Insomnia | Inability to sleep makes people irritable and less productive | 2 DNA |
| Cysts | Painful lumps containing pockets of the pathogen. Slight chance of bursting which can spread disease | 2 DNA |
| Anaemia | Decrease in red blood cells or haemoglobin in the blood can lead to hypoxia in the organs | 2 DNA |
| Vomiting | The expulsion of infected material through projectile vomiting increases the risk of infection | 4 DNA |
| Pneumonia | Serious fluid build and discharge from the lungs. People in cold climates especially vulnerable | 6 DNA |
| Sweating | The loss of fluid through sweating increases infection rates due to poor hygiene. More dangerous in cold countries | 7 DNA |
| Paranoia | Irrational delusions and mental symptoms. Victims distrust of others makes them unlikely to seek treatment or cooperate with others | 5 DNA |
| Hyper sensitivity | Increases likelihood of allergic reactions which can distract the immune system. Rich nations particularly vulnerable. | 2 DNA |
| Abscesses | Pockets of infected flesh are painful and act as breeding grounds for the pathogen, increasing infection rates when burst. | 2 DNA |
| Haemophilia | Reduced blood clotting prevents wound healing. Pathogen able to spread through infected blood | 3 DNA |
| Sneezing | Fluid discharge through sneezing greatly increases infection rates. | 5 DNA |
| Pulmonary Oedema | Potentially fatal heart abnormality causes breakdown of respiratory system, releasing pathogens into the air. | 7 DNA |
| Tumours | Pathogens disrupt cell growth pathways, causing uncontrolled, eventually fatal tumour growth | 11 DNA |
| Internal Haemorrhaging | Flesh eating pathogens breaks down arterial membranes causing rapid internal bleeding and death | 12 DNA |
| Fever | Increase in temperature, contagiousness and severe dehydration, which can be fatal | 9 DNA |
| Skin Lesions | Breakdown in the epidermis causes large open wounds which significantly increases infectivity. | 8 DNA |
| Seizures | Random blackouts and fits reduce the patient's ability to function independently. Can be fatal | 4 DNA |
| Inflammation | Inflammation obstructs bodily processes. Swelling can obstruct breathing and be fatal | 5 DNA |
| Diarrhoea | Pathogen active in digestive tract, causing infection through faeces and potentially lethal dehydration. Poor countries V. vulnerable. | 6 DNA |
| Dysentery | A complete breakdown in the digestive tract causes infected sewage, dehydration, starvation and death | 19 DNA |
| Insanity | Neuropathic action of the pathogen in the frontal lobe causes severe emotional and behavioural abnormalities. Significantly harder to cure. | 18 DNA |
| Necrosis | Large swathes of infected tissue lose blood supply and become fatal sources of gangrene. Decomposed bodies remain a vector of transmission | 27 DNA |
| Hemorrhagic Shock | Failure of the heart to pump effectively causes oxygen deprivation, loss of consciousness and death | 23 DNA |
| Paralysis | Pathogen destroys motor neurons to cause paralysis. Significantly harder to cure and lethal | 10 DNA |
| Coma | Neuropathic effects in the brain stem cause loss of consciousness and sometimes death. Significantly harder to cure | 21 DNA |
| Systemic Infection | Pathogen affects multiple organ and tissue types, causing body-wide infections that spread fast and can be fatal | 17 DNA |
| Pulmonary Fibrosis | Scarring of the lungs causes shortness of breath and extreme coughing. Can be fatal when combined by intense exercise | 6 DNA |
| Immune Suppression | Pathogens attach to lymphocytes, suppressing immune system and allowing significantly greater freedom of mutation.Can be fatal. | 12 DNA |
| Total Organ Failure | Catastrophic cell death of multiple tissue types causes body-wide organ failure and rapid death | 28 DNA |
