Factors associated with Rift Valley fever in south-west Saudi Arabia

Author(s) : A.A. Elfadil, K.A. Hasab-Allah & O.M. Dafa-Allah

Summary :

The authors undertook a study of environmental and animal risk factors associated with Rift Valley fever (RVF) in south-west Saudi Arabia. An enzyme linked immunosorbent assay was used to detect the presence of immunoglobulin M (IgM) and immunoglobulin G (IgG) antibodies against the RVF virus in serum samples from sentinel animals. In addition, a further 32 known IgM-positive serum samples were tested using the reverse transcription polymerase chain reaction (RT-PCR) to detect the RVF virus genome. The results were analysed using the univariate odds ratio (OR). To control for confounding, Mantel-Haenszel adjusted odds ratio (M-H OR) was used. Positive associations were found between RVF and the following factors: a dense mosquito population (OR = 4.2), high rainfall (M-H OR = 2) and the presence of lakes and/or ponds (M-H OR = 2.2). The RVF virus genome was detected in four (12.5%) serum samples, indicating an early stage of RVF.
