Recently, I booked a vacation to Sweden (the south). Because I was so happy to go there, I bought a few books about it. Then, I noticed that there is a chance that you can be bitten by mosquitoes and another bug (which I don't know the name of) that causes Lyme disease. To verify if that was true I went to my doctor and she adviced me to take three syringes. I was completly shocked. I'm not really a city tripper, but I want to discover Sweden's nature. Is there a big chance that you can get a bite?
Is Sweden full of mosquitos during the summer?
Full, no, but mosquitos are pretty much everywhere. The most recent ECDPC data indicate little to no invasive mosquito activity in Sweden so at least Zika is not a specific concern. Details at Mosquito Maps
Is there a big chance that you can get a bite?
The chances of getting bit by Ticks or anything in Sweden are not meaningfully higher or lower than anywhere else. You should apply the same precautions you would in any wooded area. Preventing Tick Bites
