The tick-borne Crimean-Congo hemorrhagic fever in Africa, Asia, Europe, and America: what about Egypt?

Globally, the recognized number of distinct and epidemiologically important diseases transmitted by ticks has increased considerably during the last 4 decades. Crimean-Congo haemorrhagic fever (CCHF) is a tick-borne disease caused by an arbovirus, which was first recognized during a large outbreak among agricultural workers in the mid-1940s in the Crimean Peninsula. Humans become infected through the bites of ticks, by contact with haemorrhage from nose, mouth, gums, vagina, and injection sites of a CCHF patient during the acute phase or follow-up, or by contact with blood or tissues from viremic livestock. This paper reported three human Crimean-Congo haemorrhagic fever cases, one in Almaza fever hospital and two in Gharbia Governorate. No doubt, distribution of tick-vector (Hyalomma spp.) worldwide including Egypt and presence of CCHF in regional countries must be considered by the Health and Veterinary Authorities.
