伝染病のシミュレーション

伝染病のシミュレーション
緑：健康
黄：潜伏期間
赤：発症
青：免疫獲得
灰：死亡
感染率：接触時の感染率(0～100％)
毒性の強さ：発症時のＨＰ減少の大きさ(0-999)
潜伏期間：感染から発症までの期間
発症時間：周りに感染を広めながらＨＰが減少していく期間
免疫期間：発症終了後に抗体ができて再感染しない期間
移動：人の移動量の設定(４段階)
国境：国境移動の制限(検疫：発症している人のみ通行不可　封鎖：完全封鎖)
隔離：「ON」にすると発症している人を画面右下方向に隔離
左クリックでワクチンを適用(30%の確率で免疫を獲得)
　解説など：http://game.g.hatena.ne.jp/Nao_u/20090430#p1
