Migratory Birds’ Ticks Can Spread Viral Haemorrhagic Fever

ScienceDaily (Oct. 22, 2012) — A type of haemorrhagic fever (Crimean-Congo) that is prevalent in Africa, Asia, and the Balkans has begun to spread to new areas in southern Europe. Now Swedish researchers have shown that migratory birds carrying ticks are the possible source of contagion.

The discovery is being published in the US Centers for Disease Control and Prevention journal Emerging Infectious Diseases.

Crimean-Congo Haemorrhagic fever is a serious disease that begins with influenza-like symptoms but can develop into a very serious condition with high mortality (30%). The disease occurs in Africa, Asia, and the Balkans but it has recently started to spread to new areas in southern Europe.
