Vole fever spreading further south in Sweden

Researchers have discovered that bank voles in Skåne, southern Sweden, carry a virus that can cause hemorrhagic fever in humans. This finding was made more than 500 km south of the previously known range.

Bleeding

Bleeding, technically known as hemorrhaging or haemorrhaging (see American and British spelling differences) is the loss of blood or blood escape from the circulatory system. Bleeding can occur internally, where blood leaks from blood vessels inside the body or externally, either through a natural opening such as the vagina, mouth, nose, ear or anus, or through a break in the skin. Desanguination is a massive blood loss, and the complete loss of blood is referred to as exsanguination. Typically, a healthy person can endure a loss of 10–15% of the total blood volume without serious medical difficulties, and blood donation typically takes 8–10% of the donor's blood volume.
