Prevention and control measures for Crimean-Congo haemorrhagic fever

Prevention and control of CCHF infection is achieved by avoiding or minimising exposure to infected ticks by using tick repellents. Wearing protective clothing and early and correct removal of ticks are recommended. Since nosocomial cases of CCHF are quite common and often result in high mortality, strict universal precautions, including barrier nursing, should be taken with hospitalised cases, as with other haemorrhagic fevers. A vaccine derived from inactivated mouse brain is used in Bulgaria, but is not widely available, and efficiency and safety have to be re-evaluated, as well as specific human immunoglobulin used for post-exposure prophylaxis. In endemic areas, a measure of tick control has been achieved by environmental sanitation of underbrush habitats. Acaricides may be useful on domestic animals to control CCHF virus-infected ticks if used 10–14 days prior to slaughter or to export of animals from enzootic regions.

Personal protective measures against tick bites

The risk of tick-borne infections is reduced by avoiding tick bites and removing ticks from the body. Ticks live on the ground and climb 20 to 70 cm onto grasses and bushes where they find hosts with the help of temperature-sensitive cells. The bite is painless, and often you will not sense a tick moving on your skin.
