Crimean-Congo hemorrhagic fever: Pathogenesis, transmission and public health challenges

Figure 4 Petechiae on the hand of a Crimean-Congo hemorrhagic fever patient. Petechiae are small red or purple spots resulting from capillary bleeding under the skin, commonly seen in the hemorrhagic phase of Crimean-Congo hemorrhagic fever. These non-blanching spots, distributed unevenly across the skin, indicate the severity of infection and can be accompanied by additional hemorrhagic symptoms like ecchymosis and mucosal bleeding.
