Crimean-Congo hemorrhagic fever (CCHF) is a viral haemorrhagic fever transmitted by ticks.
The disease was first described in the Crimea in 1944 and given the name
Crimean haemorrhagic fever. In 1969 it was recognized that the pathogen causing
Crimean haemorrhagic fever was the same as that responsible for an illness
identified in 1956 in the Congo, and linkage of the two place names resulted in
the current name for the disease and the virus. It is endemic in
Eurasian countries such as, Turkey, Pakistan, Afghanistan and Iran. CCHF virus
is spread by the Hyalomma tick, which is found mainly on cattle and sheep.
Muslim countries, in which these animals are sacrificed during Eid-Al-Adha, are
among the countries where CCHF is endemic, and it has been observed that CCHF
is associated with practices surrounding the Eid-al-Adha festival. The dates
for Eid-Al-Adha drift 10 days earlier in each year according to Georgian
calendar. In this year, the eid is occurring in summer season.
 Environmental hygiene and personal protection are essential parts of


The CCHF virus is transmitted to people either by tick bites or through contact with infected animal blood or tissues during and immediately after slaughter. The majority of cases have occurred in people involved in the livestock industry, such as agricultural workers, slaughterhouse workers and veterinarians.

Human-to-human transmission can occur
resulting from close contact with the blood, secretions, organs or other bodily
fluids of infected persons. Hospital-acquired infections can also occur due to
improper sterilization of medical equipment, reuse of needles and contamination
of medical supplies.

Signs and Symptoms

If you get bitten by an infected tick,
or come in close contact of an infected person or animal’s body fluids, seek
immediate medical attention if you start showing the following symptoms. These
symptoms appear within 1 to 3 days of the transmission and initially resemble
symptoms of flu. As the disease progresses, you will most likely experience the
following indications:

After 2 days, you may start showing
additional symptoms including:

  • High grade fever
  • Stomach pain
  • Diarrhea
  • Myalgia (muscle aches)
  • Headache 
  • Nausea
  • Sensitivity to light
  • Excessive sleepiness
  • Depression
  • Localized abdominal pain in the upper right side
  • Rashes on the skin
  • Jaundice
  • Severe nosebleeds
  • Uncontrolled bleeding

Congo Virus has a high fatality rate
of up to 40%; thus if suspected, it needs immediate medical attention. If
diagnosed late, these symptoms are difficult to control and can lead to organ
failure and eventually death. Hence, early intervention is crucial.


General supportive care with treatment of symptoms is the main approach to managing CCHF in people.

The antiviral drug ribavirin has been used to
treat CCHF infection with apparent benefit. Both oral and intravenous
formulations seem to be effective. In severe cases, consult to veterinary

and Control

It is difficult to prevent or control CCHF infection in
animals and ticks as the tick-animal-tick cycle usually goes unnoticed and the
infection in domestic animals is usually not apparent. Furthermore, the tick
vectors are numerous and widespread, so tick control with acaricides (chemicals
intended to kill ticks) is only a realistic option for well-managed livestock
production facilities. There are no vaccines available for use in animals.

In the absence of a vaccine, the only way to reduce
infection in people is by raising awareness of the risk factors and educating
people about the measures they can take to reduce exposure to the virus.

When buying the sacrificial animals or caring
for animals

  • Inspect the animal body to check for ticks each day.
  • Do not touch or crush the tick with your bare hands.
  • Do not try to remove the tick with your fingers.
  • Wear light colored, full sleeve clothes and shoes with socks.
  • Apply an insect repellent on the exposed area of body.
  • Must take precautions against accidental exposure.
  • Should take precautions to prevent serious injury to themselves and others.
  • Take a shower and change your clothes as soon as you return home.


  • Cover
    your mouth and nose during start of slaughtering.
  • Avoid
    backyard animal slaughtering practice.
  • Slaughtering
    should be done in abattoirs or restricted places.
  • If your
    hands are blood stained, do not rub your eyes or nose.
  • Should
    not handle the hide without gloves.
  • Try to
    keep your hands clean by washing frequently.
  • If soap
    and water is not available, use plain water or tissue.
  • The offal
    and leftover of the animal should be disposed-off properly.
  • Slaughter
    area should be washed and cleaned after the Qurbani.
