Many factors complicate efforts to calculate a case fatality ratio while an outbreak is still evolving 疾病仍處于暴發(fā)期時很多因素使計算病例病死率的努力復(fù)雜化。
One method of overcoming this difficulty is to calculate the case fatality ratio using only those cases whose final outcome ? died or recovered ? is known 一種克服這個困難的方法是僅用那些最終已知的病例死亡或痊愈來統(tǒng)計。
