Crimean-Congo haemorrhagic fever (CCHF) and Dengue in Pakistan

OCTOBER 25, 2010 - As of October 15, the IHR National Focal Point, Pakistan Ministry of Health, reported 26 cases to WHO, including 3 deaths, of Crimean-Congo Hemorrhagic Fever (CHF). In addition, more than 1,500 laboratory-confirmed dengue cases, including 15 deaths, have also been reported in Pakistan so far.




CCHF and dengue are endemic in Pakistan, with a seasonal increase in cases. Recently, however, transmission of CHF Canada and dengue fever has increased in the country with increased incidence and geographic expansion. The recent floods in Pakistan may have contributed to this upsurge due to changing risk factors for these diseases.




Operational Response

The Ministry of Health has intensified its response activities to prevent and mitigate FCC and dengue fever, including exposure awareness and preventive measures for the general public, strengthening clinical management and management. cases of patients with haemorrhagic fever, storing appropriate drugs and personal protective equi…

Crimean-Congo Haemorrhagic Fever Disease

CCHF is viral illness that occurs in Africa, the Balkans, the Middle East and Asia, in countries south of the 50° parallel north. • The principal reservoir and vector of CCHF are ticks of the genus Hyalomma, although other tick genera can be infected with CCHF virus. • The CCHF virus is transmitted to humans mainly by tick bites or through contact with infected animal blood or tissues during and immediately after slaughter. • 88% of people infected will have subclinical symptoms. One in eight people will develop a severe disease.



Clinical features of CCHF disease

• The incubation period ranges from 2-14 days. • 70% of CCHF cases have a history of tick bite. • It is estimated that 88% of infections are subclinical. • Case fatality ratio can reach 15% among patients hospitalized with severe presentation. • Most common symptoms include: • Abrupt onset fever, chills, shudders, myalgia, headaches, sicknesses and vomits, abdominal pain, arthralgia; • After a few days: bleeding from mucous mem…

Crimean-Congo haemorrhagic fever (CCHF)

Crimean-Congo haemorrhagic fever is a viral haemorrhagic fever transmitted by ticks. It can be responsible for serious epidemics in humans, but it is not pathogenic for ruminants, their amplifying host.




The disease was described for the first time in Crimea in 1944 as Crimean haemorrhagic fever. In 1969, it was recognized that the pathogen responsible for Crimean haemorrhagic fever was the same as that responsible for a disease identified in 1956 in Congo, and the coupling of the two place names gave the current name of the disease. disease and the virus.






Crimean-Congo haemorrhagic fever (CCHF) spreads to humans either by tick-bites, or through contact with viraemic animal tissues during and immediately post-slaughter. CCHF outbreaks constitute a threat to public health services because of its epidemic potential, its high case fatality ratio (10-40%), its potential for nosocomial outbreaks and the difficulties in treatment and prevention. CCHF is endemic in all of Africa, the Balkans, t…

Crimean-Congo haemorrhagic fever

Main facts

Crimean-Congo haemorrhagic fever virus (CCHF) causes outbreaks of severe viral haemorrhagic fever.

Outbreaks of Crimean-Congo haemorrhagic fever have a fatality rate of up to 40%.

The virus is transmitted primarily to humans from ticks and farm animals. Human-to-human transmission can occur as a result of direct contact with blood, secretions, organs, or body fluids of infected individuals.

Crimean-Congo hemorrhagic fever is endemic in Africa, the Balkans, the Middle East and Asia, in countries below 50 degrees north latitude.

There is no vaccine for humans or animals.

Crimean-Congo hemorrhagic fever (CCHF) is a common disease caused by a tick-transmitted virus (Nairovirus) of the family Bunyaviridae. It causes outbreaks of severe viral haemorrhagic fever, with a lethality rate of 10 to 40%.

It is endemic in Africa, the Balkans, the Middle East and Asia, in countries below 50 degrees north latitude, the geographical limit of the main vector species, a tick.
