- Abstract
Crimean-Congo Haemorrhagic Fever (CCHF) is a severe viral disease with high mortality 30-50%. Following a short incubation period there is an influenza-like illness with fever and haemorrhagic manifestations. The virus is transmitted by ticks of genus Hyalomma, with intermediate vertebrate hosts. Human become infected through tick bites, crushing an infected tick, or at the slaughter of viraemic livestock. In naturally occurring epidemics, cases do not show narrow clustering and person-to-person spread is rare. However, nosocomial spread appears to occur. CCHF could be delivered by aerosol or vectors and is recognized (NATO Handbook) as potential agent of Biological Weapon.The prophylaxis in Bulgaria is complex of general epidemiological and hygiene activities and specific immunoprophylaxis on risky people (military men, forest and field workers) with the Bulgarian licensed, specific and original vaccine, has no analog in the world. The occurred relative reduction of Morbidity and Mortality rate of CCHF recent years in Bulgaria correlates with the adequate prophylactic policy of Ministry of Health, especially the National Program for Control and Prevention of Tick-born Diseases (2004).
