Causes of African horse sickness

African horse sickness is caused by a virus called African horse sickness virus. This virus is mainly spread through the bites of small insects called Culicoides, also known as midges. These insects become infected with the virus after feeding on the blood of infected animals, such as horses, zebras, or donkeys. The virus then replicates in the insect's body and can be transmitted to other animals when the infected insect feeds on them.

When an animal is infected with African horse sickness virus, it can develop different forms of the disease depending on the strain of the virus. The virus can affect the respiratory system, causing symptoms like coughing and difficulty breathing, or it can affect the circulatory system, leading to symptoms such as fever, swelling of the body, and ultimately, death in severe cases. The disease can spread quickly through a population of animals, especially in areas where the Culicoides insect vectors are abundant.

Who is affected by it

African horse sickness affects horses, mules, and donkeys. It is caused by a virus carried by certain insects like mosquitoes. When these insects bite an infected animal, they can transmit the virus to healthy animals. This sickness mainly affects animals in Africa, but it can also spread to other regions like the Middle East and Southern Europe. It can be very harmful to horses, causing symptoms like fever, difficulty breathing, and swelling, and in severe cases, it can be fatal. Additionally, African horse sickness can have a significant impact on the equine industry, as it may lead to restrictions on the movement of animals in affected areas.

Types of African horse sickness

African horse sickness comes in different types, called serotypes. There are nine serotypes of African horse sickness virus: serotype 1 through serotype 9. Each serotype has its own unique genetic makeup and characteristics. These serotypes may vary in their impact on horses, including the severity of the disease they cause. Some serotypes may be more common in certain regions, while others may be more rare. It is important to understand the different serotypes of African horse sickness virus in order to effectively prevent and control outbreaks of the disease.

Diagnostic of African horse sickness

African horse sickness is diagnosed by testing blood samples from horses suspected of being infected. These blood samples are usually analyzed using laboratory techniques to detect specific antibodies or viral genetic material associated with the disease. In addition to blood tests, veterinarians may also consider clinical signs and symptoms observed in infected horses to help make a diagnosis. It is important to diagnose African horse sickness promptly to prevent its spread and implement appropriate treatment and control measures.

Treatment of African horse sickness

African horse sickness is a serious disease that affects horses and other equids. Treatment for African horse sickness is mainly focused on alleviating the symptoms and providing supportive care.
