Anyone know the why the US has such lower rates of mosquito-borne illnesses?<p>I know there was a big malaria eradication campaign in the middle of the 20th century that had an impact. Apparently in 1882 we had malaria not just in Florida, but straight up to North Dakota. [0]<p>Actually, weird, that graph makes it look like most malaria died off in the US before Müller&#x27;s discoveries about DDT. How&#x27;d that happen?<p>My next guess would be air conditioning helping to keep people indoors, but a lot of the range of malaria died off even before that.<p>[0] <a href="http:&#x2F;&#x2F;www.cdc.gov&#x2F;malaria&#x2F;about&#x2F;history&#x2F;elimination_us.html" rel="nofollow">http:&#x2F;&#x2F;www.cdc.gov&#x2F;malaria&#x2F;about&#x2F;history&#x2F;elimination_us.html</a>
