Beta-HCH was present in elevated levels in some patients as recently as 2009. It was manufactured by exhausting chlorination of benzene and for this reason was called erroneously beta-BHC. This synnonym still persists. In March 2005‚ the Italian

Global epidemics Man-made and natural disasters can intensify the risk of epidemics considerably‚ as can conditions in crowded refugee camps. Explosive outbreaks with high case-fatality rates are often the result. For example‚ in the aftermath of the Rwanda crisis in 1994‚ outbreaks of cholera caused at least 48 000 cases and 23 800 deaths within one month in the refugee camps in Goma‚ the Congo. Although rarely so deadly‚ outbreaks continue to be of major public health concern‚ causing considerable
