Observations on African horse sickness in Saudi Arabia.

The research article is about studying the presence of African horse sickness in Saudi Arabia. The study found that there is no virus activity for this disease in the examined time period, indicating that it is not normally present in the region.

Overview of Research

The research focuses on the epidemiological status of African horse sickness in Saudi Arabia. An epidemiological study refers to the analysis and investigation of the patterns, causes and effects of certain diseases among particular populations. The researchers used several methods to identify whether the disease is present or not:

• Seroconversion: This refers to the process by which a bacterium or virus stimulates the immune system to produce antibodies. In this study, the researchers probably tested the blood of certain horses in Saudi Arabia to see if they had antibodies against the African horse sickness virus.
• Virus isolation: This technique implicates separating the virus from the blood samples to study its traits and properties.
• Clinical observation of sentinel horses: Sentinel animals are those that are used in studies to understand the prevalence of a certain disease. They are closely monitored and any signs of disease are noted.

Results of the Research

The research was conducted from November 1992 to March 1995 and during this period, no virus activity related to African horse sickness was detected in Saudi Arabia. This conclusion backs earlier reports stating that this disease is not endemic in the region. An endemic disease is one that is constantly present to a greater or lesser degree in people of a certain class or in people living in a particular location. So, in the context of this study, the absence of the disease signifies that it is not regularly found in the horse population of Saudi Arabia.
