Two more people have died in Spain as a deadly virus carried by mosquitoes continues to spread. Five people have now died of West Nile Virus in the Seville area of Spain. The regional Government for the area, the Junta de Andalucia has now identified another 10 cases of the disease. There are fears the disease could spread across Spain.
The UK Foreign Commonwealth and Development Office warns: “There is a risk of insect or tick-borne diseases in some areas of Southern Europe. This includes diseases such as Crimean-Congo haemorrhagic fever, leishmaniasis and West Nile virus. All travellers should avoid insect and tick bites day and night. There are no vaccinations (or medications) to prevent these diseases.”
The European Centre for Disease Prevention and Control has reported 713 cases of West Nile virus, and 67 deaths, across nine European countries, including Greece. West Nile Virus is a mosquito-borne virus that can cause severe neurological disease in humans. Discovered in Uganda in 1937, it has since spread worldwide due to climate change. Most infections are asymptomatic, but severe cases can lead to life-threatening conditions. Preventive measures, such as controlling mosquito populations and avoiding mosquito bites, are crucial in limiting the spread.
It is part of the Flavivirus genus, which also includes other viruses like Zika, dengue, and yellow fever. WNV is spread to humans mainly through the bite of an infected mosquito, particularly the Culex species. WNV began spreading to Europe in the 1950s, with several outbreaks in the Mediterranean region, and is now considered endemic in many parts of North America.
Most people infected with WNV do not show symptoms, but severe cases can have symptoms ranging from mild, such as fever and body aches, to severe symptoms like encephalitis and meningitis, with potential fatal outcomes, particularly in older adults or those with weakened immune systems. It is essential for travellers to be aware of the risks and take precautions when visiting affected areas to prevent infection and spread of the virus.
The UK and other European countries are closely monitoring the situation and providing guidance to the public on how to stay safe and avoid exposure to mosquitoes carrying the virus. Stay updated on the latest developments and follow health recommendations to protect yourself and others from the spread of mosquito-borne diseases.
