The Crimean Congo Hemorrhagic Fever (CCHF)

The Crimean Congo Hemorrhagic Fever (CCHF)

Context:

The Palghar, Maharashtra administration has asked authorities to remain alert against a possible spread of the Congo fever in the district.

Details:

  • This is a matter of concern for cattle- breeders, meat-sellers, and animal husbandry and it is necessary to take timely precautions as there is no specific and useful treatment for the Crimean Congo Hemorrhagic Fever (CCHF).
  • Palghar animal husbandry department’s deputy commissioner mentioned that the CCHF has been found in some districts of Gujarat and is likely to spread to border districts of Maharashtra.
  • The department has instructed authorities to take all necessary precautions and implement preventive measures.

The Crimean Congo Hemorrhagic Fever (CCHF):

  • It is commonly known as Congo fever. This viral disease is transmitted from one animal to another by a specific type of tick.
  • The disease is transmitted to humans through contact with the blood of infected animals and by eating the meat of infected animals.
  • If the disease is not diagnosed and treated in time, 30 % of patients die.
  • The CCHF is a widespread disease caused by a tick-borne virus (Nairovirus) of the Bunyaviridae family.
  • The virus causes severe viral haemorrhagic fever outbreaks, with a case fatality rate of 10 to 40 %, as per the World Health Organisation (WHO).
  • 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, according to the WHO.

Treatment:

  • The antiviral drug ribavirin has been used to treat CCHF infection with apparent benefit.
  • There are no vaccines widely available for human or animal use.
