I was stunned when I came across this article about an epidemic of Dengue fever in Austin, TX (where I live) in 1885 and other cities across the southeastern tier of the US. Dengue Fever is returning to the US and it is not a new incursion:
Dengue, aka “Breakbone Fever,” Is Back
The vicious virus has re-established itself in the South, and mosquitoes are carrying it north.
In the autumn of 1885, people in Austin, Texas, began to feel sick. One after another, they developed a chill and then a soaring fever. They vomited and broke out in rashes. Their most distinctive symptom was agonizing pain behind their eyes and in the bones of their arms and legs. And when the fever subsided, lack of appetite and deep exhaustion left them unable to work for weeks or months.
Austin had been founded only 46 years before, and it was still small, with just 22,000 people. By the time the epidemic was over, 16,000 of them had fallen ill. A local doctor who described the outbreak in the Journal of the American Medical Association the following year added: “I am informed that other cities ... had as many cases in proportion to the population as did Austin.”
The illness that took out Texas that fall had already devastated Charleston, S.C., in 1828 and Savannah, Ga., in 1850, and it would go on to sicken half the population of Galveston, Texas, in 1897; one-quarter of Monroe, La., in 1922; and one out of every nine people in Miami in 1934. It was dengue—a mosquito-borne virus popularly known as “breakbone fever” for the pain it caused. From the 1820s to the 1940s, it caused recurring epidemics roughly every 10 years.
As noted in the article, DDT spraying campaigns ended Dengue epidemics in the US. Those of us who are older likely remember tanker trucks in our neighborhoods spraying clouds of insecticide. This ended in the 1970s. In addition, I suspect the advent of widespread air conditioning reduced mosquito exposure in general.

A fellow cyclist that I ride with often was diagnosed with West Nile in August 2012. For him it was like an extremely bad case of the flu with a prolonged recovery. He is pretty sure he was bitten while sitting on his patio for his regular post work glass of wine.
