During the summer and fall of 1941, 19 samples of flies were collected in epidemic areas both during and after epidemics of poliomyelitis. Of 8 samples collected for the most part during the latter part of a local epidemic but within 10 days of the onset of a local case of poliomyelitis, 4 yielded the virus; whereas of 8 samples collected more than 10 days from the onset of the last local case, none yielded the virus. In 4 instances there was a potential (though not proven) source of virus (in the form of "exposed" human feces of recent origin) within a few yards or few feet of the site where fly collections were made. Collections of flies from 3 of these sites yielded the virus. No attempt is made in this paper to develop epidemiological implications from this finding.
1941 年夏秋季，在脊髓灰质炎流行地区采集了 19 份苍蝇标本，这些标本是在流行期间和流行后采集的。在当地流行后期，但在当地脊髓灰质炎病例发病后 10 天内采集的 8 份样本中，有 4 份分离出病毒；而在最后一例当地病例发病后 10 天以上采集的 8 份样本中，没有一份分离出病毒。在 4 个情况下，苍蝇采集点附近几码或几英尺范围内有潜在（尽管未经证实）的病毒来源（以最近来源的“暴露”人类粪便的形式）。从这 3 个地点采集的苍蝇样本都分离出了病毒。本文并未试图从这一发现中得出流行病学意义。
