Health and Safety
When it comes to crime, Sweden has quite a lower rate than most Western countries. However, this isn’t to say that it never occurs. In the larger cities like Stockholm, petty theft and robberies do happen, and street violence associated with clubbing is not uncommon. Therefore, visitors should avoid walking alone at night, and if a fight does break out, keep your distance and use common sense.
When it comes to safety in Sweden, the weather is definitely one of the most influential factors in the country. During the cold long winter, blizzards are common in the central and northern areas. This makes driving difficult and dangerous during the colder months. In the mountainous areas, avalanches are common, which can be extremely fatal, so always check with local guides before going skiing, and make sure to bring company.
Wild animals are rare in Sweden. Mosquitoes can be quite nasty during the summer months. They generally don’t carry diseases, but the high numbers that hang around can cause annoying and sometimes painful bites. Ticks are a cause for concern in parts of Sweden. These little insects can carry viruses and diseases, including Lyme’s disease and a special type of encephalitis so be conscientious when hiking.
