This summer the pleasant pattern for contemplation was threatened. The municipal health department decided to attack the fly and mosquito population by air-spraying the town with DDT solution. Private goldfish fanciers were outraged at the danger to the fish population...
Finally, the assembly heard reports on the work of missions sent out by the interim commission that preceded the present permanent organization (TIME, April 5). Said Dr. Neville Gordon, pipe-smoking British head of WHO field services, about DDT-spraying planes in Greece: "Our slow, low-flying planes could be shot down like ducks by anybody with a gun on a hill [but] the rebels even sent guides through the lines to our spraying teams, asking them to come up and spray rebel-held villages."

But with the now common household spray DDT, "it is a safe statement that at least 90% of the malaria of the world can be wiped out in the next ten years, and that's conservative," said Dr. Fred Soper of the Pan American Sanitary Bureau...
What could be done about malarial mosquitoes which escape DDT campaigns? Four war-born drugs help their victims, the conference was told: 1) chloroquine, more active than quinine or atabrine, and much less toxic; 2) pentaquine, which has reduced the relapse rate in the vivax form of malaria from 98% to 25%; 3) iso-pentaquine, a variant of pentaquine, so far tried on only 100 cases; 4) Paludrine, which controls vivax malaria with a single dose...

Some 100,000 children were examined and more than three million home visits were made. In time Maracay was declared malaria-free and the area of treatment was expanded...
