**Title: Five Horses Diagnosed with West Nile Virus in Cyprus**
The Veterinary Services Department of Cyprus has confirmed that five horses have tested positive for West Nile virus. The diagnosis was made following tests conducted between September 9 and the end of last week. All affected horses are reported to be alive but have shown symptoms such as fever and weakness while walking. Fortunately, these symptoms appear to have lessened in recent days.
According to the department, all five horses originate from the same premises, prompting an epidemiological investigation into the situation. The initial examination was initiated due to the symptoms exhibited by one of the horses, leading to further testing of the animals.
The Veterinary Services Department has clarified that West Nile virus is not transmitted directly between horses or from horses to humans. Instead, the virus is spread through infected mosquitoes. The World Health Organization (WHO) emphasizes that human infections typically occur as a result of mosquito bites. Mosquitoes become carriers of the virus after feeding on infected birds, which can harbor the virus in their bloodstream for a short period. The virus then migrates to the mosquito’s salivary glands, allowing it to be transmitted during subsequent blood meals.
West Nile virus is known to be asymptomatic in approximately 80% of cases. However, the remaining 20% of infected individuals may develop West Nile fever, characterized by symptoms such as fever, headache, fatigue, body aches, nausea, vomiting, and occasionally a skin rash or swollen lymph glands. In more severe instances, the virus can lead to complications such as encephalitis or meningitis, which present with symptoms including severe headache, high fever, neck stiffness, confusion, and in extreme cases, paralysis.
The WHO notes that while serious illness can occur in individuals of any age, those over 50 and individuals with compromised immune systems are at a heightened risk of severe outcomes from the virus. Approximately one in 150 people infected with West Nile virus may develop a more serious form of the disease.
The Veterinary Services Department is continuing to monitor the situation closely and has urged horse owners and the public to remain vigilant regarding mosquito control measures, especially in light of the recent diagnoses. They recommend that individuals take precautions to avoid mosquito bites, particularly in areas where the virus has been detected.
As the situation develops, the department will provide updates and guidance to ensure public health and safety.
