700 Bulgarians have been diagnosed with haemophilia. 100 of them are children. The disease is usually hereditary, and the recommendation to families is to have their newborn boys tested at birth. Until recently, it was thought that only males could be affected by hemophilia, but there are also women who have blood clotting problems, which can be life-threatening, and there is still no mechanism for their treatment in Bulgaria. Medical specialists drew attention to this issue on the occasion of April 17, World Haemophilia Day. 

World Haemophilia Day was started in 1989 by the World Federation of Hemophilia. It aims to raise awareness of Haemophilia and other inherited bleeding disorders. On the occasion of World Haemophilia Day, the Bulgarian Haemophilia Association organized a cycling event in Sofia, Plovdiv and Varna. The event will take place on April 20 under the motto "Together". 

In the capital city, the cycling event starts at 11 a.m. from the pylons in front of the National Palace of Culture. In Plovdiv, the event starts from Saedinenie Square. In Varna, cyclists will pass through the Sea Garden to draw attention to the scarce information about hemophilia that reaches our society."
