Rift valley fever virus infections in egypt: Pathological and virological findings in man

Ten strains of Rift Valley Fever virus were isolated from serum samples from acute human cases collected during an epidemic of undifferentiated febrile illness. Post-mortem samples were obtained from two fatal infections. Severe liver necrosis, interstitial pneumonia and myocardial degeneration were seen. Rift Valley Fever virus was isolated from post-mortem samples of liver, cerebro-spinal, pericardial and pleural fluid and from a throat swab. The virus was also isolated from nasopharyngeal washings suggesting that direct transmission from man to man may be possible. © 1978 Oxford university press.
