问题 A infected body fluids
B against the outbreak severity
C the mode of transmission
D the initial days of being infected
E three countries in West Africa
F within a wide range of days
The symptoms of the patients after being infected may first appear______.

选项

答案F

解析 由第四段第二句“Symptoms may appear as early as two days or as late as three weeksafter initial infection”可知,感染埃博拉的症状可能最早在感染后两天或晚至三周才会显现,说明潜伏的天数不等,故本题应选F。
