An 84-year-old man from the village of Botevo in Bulgaria’s Yambol district has died of West Nile fever, the regional inspectorate of health in Yambol said, Bulgarian National Radio reported on September 25.
The man had been treated for a week at the Yambol infectious diseases treatment centre before succumbing.
Samples previously sent to a laboratory in Sofia had confirmed the West Nile fever infection.
This is the third publicly announced case in recent weeks in Bulgaria. At the beginning of September, the municipality of Bourgas at the Black Sea issued a warning after a woman showed symptoms of West Nile fever.
On September 3, a man in Bulgaria’s second city Plovdiv was diagnosed with West Nile fever.
West Nile fever is a viral infection typically spread by mosquitoes. In about 75 per cent of infections people have few or no symptoms. About 20 per cent of people develop a fever, headache, vomiting, or a rash. In less than one per cent of people, encephalitis or meningitis occurs, with associated neck stiffness, confusion, or seizures.
The 84-year-old from Botevo had not visited any states in which the risk of West Nile fever infection is high, nor had signs of a mosquito bite been found, according to the clinic in Yambol.
At the beginning of September, health authorities in Yambol had issued a notice to health care professionals not to exclude West Nile fever from their diagnoses.
