Denmark potentially in the firing line of five mosquito-borne diseases, warns researcher

Rift Valley Fever, West Nile Fever and Japanese Encephalitis – they sound so exotic, don’t they? Like they’re the last things you’d ever catch in Denmark.

Ditto Rabbit Fever and Eastern Equine Encephalitis. Outside a badly-run petting zoo, it doesn’t sound plausible. 

But according to an academic at the University of Copenhagen, people in Denmark might very well be in the firing line from five mosquito-borne diseases in the near future. 

One disease already in north Germany
Researcher René Bødker, the head of a project on mosquito-borne diseases, tells DR that their arrival in Denmark over the next decade is entirely possible, with West Nile Fever at the front of the queue, as there have been documented cases in northern Germany already.

“We expect it to come to Denmark shortly,” he warned. 

Out of the five, however, it is probably the most mild disease. 

Important to be aware
Today, Denmark remains one of the very few countries where you can’t get ill from being bitten by a mosquito – irritated, perhaps, because somebody booked a summerhouse next to a flea-infested swamp – but not unwell.

Bødker’s project is mapping zoonotic infections/diseases that could potentially cause epidemics in Denmark – particularly if the weather continues to get warmer and cloudbursts become even more frequent.

The public risk being taken unaware, as their first reaction would most likely be that they have contracted mild flu. By the time the illness develops into encephalitis, which causes the inflammation of the brain, it could be too late.

Sweden and Germany better prepared
“If we get hit, we need to know exactly what to do. Right now we are one of the very few European countries that do not have control of mosquitoes,” urged Bødker.

“In Sweden and Germany there are large companies that fight mosquitoes, and in France there are special planes to spray against mosquitoes.”
