The fear of Congo fever and its symptoms


Crimean-Congo Hemorrhagic Fever (CCHF) is a viral infection that is often fatal and has been described and diagnosed in about 30 countries all over the world. Due to its widespread nature, it is extensively geographically distributed, given that it is one of the most crucial tick-borne viral diseases. Congo virus is more lethal than cancer and it grows in the skin of goats and other such animals. Talking about the virus, the fear of Congo fever and its symptoms are given below to help people understand it.


According to WHO, World Health Organization

The length of the incubation period depends on the mode of acquisition of the virus. Following infection by a tick bite, the incubation period is usually one to three days, with a maximum of nine days. The incubation period following contact with infected blood or tissues is usually five to six days, with a documented maximum of 13 days.


Onset of symptoms is sudden, with fever, myalgia, (muscle ache), dizziness, neck pain and stiffness, backache, headache, sore eyes and photophobia (sensitivity to light). There may be nausea, vomiting, diarrhoea, abdominal pain and sore throat early on, followed by sharp mood swings and confusion. After two to four days, the agitation may be replaced by sleepiness, depression and lassitude, and the abdominal pain may localize to the upper right quadrant, with detectable hepatomegaly (liver enlargement).

Other clinical signs include tachycardia (fast heart rate), lymphadenopathy (enlarged lymph nodes), and a petechial rash (a rash caused by bleeding into the skin) on internal mucosal surfaces, such as in the mouth and throat, and on the skin. The petechiae may give way to larger rashes called ecchymoses, and other haemorrhagic phenomena. There is usually evidence of hepatitis, and severely ill patients may experience rapid kidney deterioration, sudden liver failure or pulmonary failure after the fifth day of illness.

The mortality rate from CCHF is approximately 30%, with death occurring in the second week of illness. In patients who recover, improvement generally begins on the ninth or tenth day after the onset of illness.

Human beings become infected with this disease after being bitten by ticks. Exposure to ticks can be caused by a number of ways such as tick bites or by crushing the infected ticks. The disease is also transmitted via contact with a patient with CCHF during the acute phase of infection, or by contact with blood or tissues from viraemic livestock.

Precautionary measures should be taken to keep oneself safe from the virus.
