Experts blamed a whole raft of things for the illness that struck several students and one teacher at Virginia's William Byrd High School: Carbon dioxide from the photography classroom. Lead paint. Drugs. Chronic Fatigue Syndrome. Even swamp gas and raging hormones.

In September 2007, a student at the high school fell ill with tremors, twitching, dizziness and headaches. Soon nearly a dozen people were afflicted, causing alarm in the school and community. School officials were urged to close the institution; at one point about 300 of the school's 1,200 students were staying home.

Virginia's Department of Health swept in, performing innumerable tests to see whether there was an environmental issue causing the symptoms. But after weeks of study, all results were negative. The conclusion: a sociogenic problem (i.e., one produced by societal issues). In other words, mass hysteria. The reason for the hysteria was presumed to be stress. However, the school superintendent was uncertain, saying these students were no more stressed than any others [source: Jeffries].
