The plagues symptoms are fairly typical of an ordinary sickness which makes it hard to detect. To figure out if a dragon has the plague you need to figure out how many symptoms are showing. More than 3 means its not the plague. (0 weeks - 5 weeks) Stage 0: Plague is incubating, no encounters. Sickness chance is minimum. (Grace period) (6 weeks to 10 weeks) Stage 1: Plague is mild, death chance is 1% every 5 days. (11 weeks to 15 weeks) Stage 2: Plague is more severe, genetic shuffles occur but no mutated or lethal traits yet. Dragons are contagious. death chance 5% every 5 days. (16 weeks to 20 weeks) Stage 3: 5% lethal mutation chance. Dragons are highly contagious. 10% death chance every 5 days. (21 weeks to 25 weeks) Stage 4: 10% lethal mutation chance. Mutated traits can occur. Infected population doubles every week when not quarantined. 25% death chance every 5 days. (26 weeks and forwards) Stage 5: 30% lethal mutation chance. Mutations rapid. Infected population triples every week when not quarantined. 50% death chance every 3 days.
Chance of new strain mutating: 5% Plague traits: L> = Lethality up 3% L< = Lethality down 3% L+ = no lethality I> = Infectivity up 3% I< = Infectivity down 3% I+ = cannot spread New strain traits: CC = coughing cc = no coughing Cc = mild cough C+ = chronic cough TT = trouble breathing tt = no trouble breathing Tt = difficulty breathing AA = aggression aa = no aggresion Aa = mild aggresion A+ = chronic irritability DD = delirium dd = no delirium Dd = mild delirium ArAr = arrhythmia aRaR = no arrhythmia AraR = mild arrhythmia Ar+ = chronic arrhythmia SS = soreness ss = no soreness Ss = mild soreness BB = raised blood pressure bb = no change in blood pressure Bb = mild increase FF = high fever ff = no fever Ff = mild fever WW = weakness ww = no weakness Ww = mild weakness ChCh = chills cHcH = no chills ChcH = mild chills DzDz = dizziness dZdZ = not dizzy DzdZ = slight dizziness CoCo = confusion cOcO = no confusion CocO = mild confusion HH = headache hh = no headache Hh = mild headache
