1977年埃及人群中发生了裂谷热的流行,该病表现为急性发热性登革热样疾病。从病人中分离到虫媒病毒,经鉴定为RVF病毒。本文采集年龄从6—40岁住院病人的双份血,少数病人同时采集咽洗液和粪便标本接种乳鼠分离病毒。从临床上诊断为登革热样病人中分离到56株病毒经补体结合试验鉴定其中53株为RVF病毒。从5份粪便标本中分离到4株RVF病毒,从3份咽洗液中也分离到2株RVF病毒。其中有1个病人,从血清、咽洗液和粪便中都同时分离到RVF病毒。过去有报告从咽洗液中分离到RVF病毒,但从粪便中分离到可能是第一次。由于从粪便中分离到RVF病毒的病人有内脏出血、包括小肠出血,因此病毒可能是原发于血液中的。
The prevalence of Rift Valley fever occurred in the Egyptian population in 1977, which manifested as acute febrile dengue-like disease. Arbovirus was isolated from the patient and identified as RVF virus. This collection of patients aged 6-40 years of inpatient double blood, a small number of patients at the same time collecting pharyngeal fluid and stool specimens inoculated suckling mice isolated virus. From the clinical diagnosis of dengue-like patients isolated 56 viruses identified by complement fixation assay of which 53 strains of RVF virus. Four RVF viruses were isolated from five stool specimens and two RVF isolates from three pharyngeal washings. One of the patients had RVF virus isolated from serum, pharyngeal fluid and feces. It has been reported in the past that RVF virus was isolated from pharyngeal fluid, but this may be the first time that it has been isolated from faeces. The virus may be of primary origin in the blood because of visceral bleeding, including intestinal bleeding, in patients with RVF virus isolated from the stool.
