If it was the case, we wouldn't have between 200 and 300 million cases of malaria every year, and we wouldn't have a million and a half deaths from malaria, and we wouldn't have a disease that was relatively unknown 50 years ago now suddenly turned into the largest mosquito-borne virus threat that we have, and that's called dengue fever.
如果真的是那样， 就不会每年有2亿到3亿人受到疟疾的侵扰； 也不会 有一百五十万人死于疟疾； 也不会让一种 50年前我们还几乎一无所知的疾病 突然变成今天的 最大病毒威胁，而这种病毒是由蚊子传播的； 这种疾病叫做登革热。
