【解析】

这篇短文主要讲述了奇卡病毒的的传播是通过蚊子，这种病毒的症状及没有治疗和疫苗。

1.细节理解。water水； mosquitoes蚊子； air空气； internet网络。根据文中“Transmitted through mosquito bites”可知，传播通过蚊子咬。故选B。

2.数字计算。根据文中“About 1 in 5 infected people will become ill.” 大约五分之一被感染的人会生病。500人中五分之一会得这种病。也就是100人。故选C。

3.推理判断。根据文中“Mosquitoes known to transmit the virus are not present in Canada.” 已知传播病毒的蚊子在加拿大不存在。可知，从加拿大的蚊子那里是不可能得这种病毒。故选A。
