法尔流行病定律于1840年首次颁布,并在20世纪初由布朗利复活,该定律指出流行病往往以大致对称的模式上升和下降,可以近似为正常的钟形曲线。我们将这一简单的定律应用于1982年至1987年美国获得性免疫缺陷综合征病例的年度发病率。6年的发病率数据非常符合正态分布,在1988年底达到峰值,然后在20世纪90年代中期下降到低点。预计这一流行病的规模福尔斯20万例左右。预计地方性病例将继续发生,但我们认为发生的水平将很低。
Farr's Law of Epidemics, first promulgated in 1840 and resurrected by Brownlee in the early 1900s, states that epidemics tend to rise and fall in a roughly symmetrical pattern that can be approximated by a normal bell-shaped curve. We applied this simple law to the reported annual incidence of cases of acquired immunodeficiency syndrome in the United States from 1982 through 1987. The 6 years of incidence data closely fit a normal distribution that crests in late 1988 and then declines to a low point by the mid-1990s. The projected size of the epidemic falls in the range of 200 000 cases. A continuing incidence of endemic cases can be expected to emerge, but we believe it will occur at a low level.
