An epizootic of Rift Valley fever in Egypt in 1977.
A disease causing increased mortality and abortion in domestic animals during a 1977 epizootic in Egypt was identified as Rift Valley fever (RVF) virus. The epizootic included extensive human involvement reflected clinically as either an acute febrile, ocular, encephalitic, or fatal haemorrhagic form of RVF disease. The virus was again isolated from humans and animals during a second RVF epizoo...
متن کاملMolecular Epidemiology of Rift Valley Fever Virus
Phylogenetic relationships were examined for 198 Rift Valley fever virus isolates and 5 derived strains obtained from various sources in Saudi Arabia and 16 countries in Africa during a 67-year period (1944-2010). A maximum-likelihood tree prepared with sequence data for a 490-nt section of the Gn glycoprotein gene showed that 95 unique sequences sorted into 15 lineages. A 2010 isolate from a p...
متن کاملModeling the spatial spread of Rift Valley fever in Egypt.
Rift Valley fever (RVF) is a severe viral zoonosis in Africa and the Middle East that harms both human health and livestock production. It is believed that RVF in Egypt has been repeatedly introduced by the importation of infected animals from Sudan. In this paper, we propose a three-patch model for the process by which animals enter Egypt from Sudan, are moved up the Nile, and then consumed at...
متن کاملA serological study of Rift Valley fever in Zambia
Evidence of infection of sheep and, to a lesser extent, cattle, with Rift Valley fever (RVF) virus was obtained from a sero-epidemiological study conducted on four farms in the Chisamba area of the Central Province of Zam bia. This area was affected by an epizootic of RVF in the 1973/74 rain season; clinical cases were again reported during the 1977/78 rains. The results suggest that RVF virus...
