Control
When a mosquito bites, she also injects saliva and anti-coagulants into the blood which may also contain disease-causing viruses or other parasites. This cycle can be interrupted by killing the mosquitoes, isolating infected people from all mosquitoes while they are infectious or vaccinating the exposed population. All three techniques have been used, often in combination, to control mosquito transmitted diseases. Window screens, introduced in the 1880s, were called "the most humane contribution the 19th century made to the preservation of sanity and good temper."

Famous quotes containing the word control:
“Why wont they let a year die without bringing in a new one on the instant, cant they use birth control on time? I want an interregnum. The stupid years patter on with unrelenting feet, never stopping—rising to little monotonous peaks in our imaginations at festivals like New Year’s and Easter and Christmas—But, goodness, why need they do it?”
—John Dos Passos (1896–1970)
“The mind is the greatest of all human forces. Control the mind and you control the body.”
—Griffin Jay, Randall Faye, and Lew Landers. Armand Tesla (Bela Lugosi)
“There has been something crude and heartless and unfeeling in our haste to succeed and be great. Our thought has been “Let every man look out for himself, let every generation look out for itself,” while we reared giant machinery which made it impossible that any but those who stood at the levers of control should have any chance to look out for themselves.”
—Woodrow Wilson (1856–1924)
