DISTRIBUTION OF YELLOW FEVER 183 there was no city on the whole Atlantic and Gulf coasts of the United States which was exempt from yellow fever epidemics, and the disease exerted a serious influence on the economic conditions, especially of our Southern States. In New Orleans there have. Fig. 57. Map showing geographic distribution of the yellow fever mosquito, Aedes calopus (black lines), and former distribution of yellow fever (red stipple). been epidemics which have cost thousands of lives, the last one occurring in 1905. In temperate cities the epidemics always ended with the coming of frost and destruction of the transmitting mosquitoes. Now the situation is quite different and there is no reason to believe that the world will ever again see such a sight as was formerly only too common — a frantic, terrorized city helpless in the grip of a deadly yellow fever epidemic. No epidemic has occurred in the United States since 1905 and many of the tropical cities, such as Havana, Manaos and Rio de Janiero, which were formerly famous as endemic centers of the disease, and from which it was carried to seaports in all parts of the world, are now practically free from it. It is only in such notoriously unsanitary cities as Guayaquil in Ecuador and Buenaventura in Colombia that yellow fever still rages, with little or no attempt on the part of the inhabitants to stamp it out.
