Methodological issues of confounding in analytical epidemiologic studies
Background: Confounding can be thought of as mixing the effect of exposure on the risk of disease with a third factor which distorts the measure of association such as risk ratio or odds ratio. This bias arises because of complex functional relationship of confounder with both exposure and disease (outcome). In this article, we provided a conceptual framework review of confounding issues in epi...

Inapparent infections in adults can lead months later to abortions, stillbirths and congenital defects in newborns. Most affected neonates die or must be euthanized. Before vaccines were developed, Akabane disease caused significant economic losses in some countries. Between 1972 and 1975, this virus r...
متن کاملAkabane Disease in Cattle
Akabane is a viral disease transmitted by mosquitoes and biting midges that affects cattle and less frequently sheep and goats. It is also commonly known as “curly calf disease” due to the deformities it can cause in foetuses when cows are infected with the virus during pregnancy. The stage of pregnancy during which the cow is infected determines the range and severity of clinical signs seen. C...
