Introduction Crimean congo hemorrhagic fever virus: The Crimean-Congo hemorrhagic fever virus is the source of the viral illness known as Crimean-Congo hemorrhagic fever (CCHF). In the Crimea in 1944 and then in the Congo in 1956, the disease was first identified. The virus mainly spreads to people through tick bites or contact with contaminated blood or body fluids from humans or other animals.

In many regions of Africa, Asia, and Europe, CCHF is endemic and has a widespread geographic distribution. It is categorised as a zoonotic illness, which means that it mostly affects animals but can also affect humans.

Causes of Crimean Congo hemorrhagic Fever

The Crimean-Congo hemorrhagic fever virus (CCHFV), a member of the Nairovirus genus in the Bunyaviridae family, is what causes Crimean-Congo hemorrhagic fever (CCHF).

The majority of the time, infected ticks, especially those belonging to the Hyalomma genus, bite humans and spread the virus to them.

Through direct contact with blood or body fluids, the virus can spread between humans or from animals to humans.

Infected objects or surfaces, such as infected needles or medical supplies, can also spread the infection. There is also proof of vertical transmission during pregnancy from an infected mother to her foetus.

Those who work with cattle, such as farmers, veterinarians, and abattoir employees, as well as healthcare professionals who come into touch with infected patients, are at a higher risk of developing CCHF. Also at risk are visitors to regions where the virus is endemic.

It is significant to remember that not all ticks carry the CCHF virus, and not everyone bitten by an infected tick will become ill. However, persons who have had close contact with sick humans or animals or those who live in locations where the virus is endemic are at the highest risk of transmission.

Geography of crimean Congo hemorrhagic Fever virus

The virus that causes Crimean-Congo hemorrhagic fever (CCHF) is mainly transmitted by ticks. The disease is named after the nations of Crimea and Congo, where it was initially discovered.

Africa, Asia, and parts of Europe are where CCHF is most prevalent. The virus has been discovered in numerous nations, including South Africa, Uganda, Zimbabwe, Afghanistan, Iran, Iraq, Pakistan, Tajikistan, Turkey, and Uzbekistan in Asia; Albania, Bulgaria, Kosovo, Romania, and Russia in Europe; and Afghanistan, Iran, Iraq, and Tajikistan in Asia.

Rural and agricultural settings, CCHF is largely linked to them in these places. Healthcare professionals and family members who are caring for ill people should be aware of the disease's potential for transmission by contact with the blood or other body fluids of infected individuals.

Sign and symptoms of Crimean congo hemorrhagic fever virus

Information on the Crimean-Congo hemorrhagic fever (CCHF) symptoms and signs:

Fever: A fever, which can range in severity from mild to severe, is frequently the first sign of CCHF.

CCHF patients may feel joint discomfort and muscular aches.

Headache: Headaches are frequent and serious in CCHF.

Dizziness: If a person is dehydrated, CCHF might make them feel lightheaded, dizzy, and even faint.

Vomiting and nausea are common symptoms of CCHF, which might make people more susceptible to being dehydrated.

Diarrhoea : Diarrhoea is yet another typical CCHF symptom.

  • CCHF patients may suffer mild to severe abdominal pain, which can range in intensity.
  • painful throat: A painful throat is a typical sign of CCHF and can make swallowing challenging.
  • Bleeding is one of the CCHF's defining symptoms. This can happen through the nose, mouth, or rectum, and in severe situations, it can result in internal organ haemorrhaging.
  • Bruising and petechiae: Petechiae are tiny, flat, red or purple spots that can appear on the skin in CCHF patients. Additionally, they might develop bruises as a result of the disease's accompanying bleeding.

Hemorrhagic fever, which is characterised by internal bleeding and shock, can develop from severe episodes of CCHF. In as many as 40% of instances, this can result in coma and death.

Diagnosis of Crimean fever Hemorrhagic Fever

The following procedures are commonly used to determine a Crimean-Congo hemorrhagic fever (CCHF) diagnosis:

Medical history and physical exam: The doctor will inquire about your recent travel experiences and any encounters with ticks or diseased animals. Additionally, they will conduct a physical examination to check for CCHF symptoms like fever, haemorrhage, and rash.

Blood and other physiological fluids will be collected for examination in a laboratory. This could involve serology testing to look for antibodies to the virus as well as polymerase chain reaction (PCR) assays to look for the virus's existence.

Differential diagnosis : The medical professional will look at several conditions that could be the source of the symptoms, such as bacterial infections or other viral hemorrhagic fevers.

Clinical diagnosis : The healthcare practitioner will determine a clinical diagnosis of CCHF based on the findings of the medical history, physical examination, laboratory testing, and imaging studies.

Confirmation : Additional laboratory testing, such as repeat PCR or serology tests, may be necessary to confirm the diagnosis.

Prevention and control of crimean Congo hemorrhagic fever

The following are some of the Crimean-Congo hemorrhagic fever (CCHF) prevention and control measures:

To prevent coming into contact with ticks, stay away from tick-prone areas, wear long sleeves and long pants for protection, use insect repellent and check your body and clothing for ticks after being outside.

Avoiding contact with infected animals: Keep your distance from any animals, including livestock, that may be carrying the CCHF virus, especially if they are ill or have recently passed away.

Use protective gear and gloves while handling animal products, such as blood or meat, and make sure the meat is completely cooked before eating.

Normal infection control measures: To stop the virus from spreading, healthcare professionals who are caring for patients with CCHF should take normal infection control measures.

Early identification and treatment can lessen the risk of complications and improve outcomes in patients with CCHF.

Vaccination : There isn't a CCHF vaccination on the market right now. However, work on a vaccination is still being done.

Public health education : Campaigns for public health education can assist spread awareness of the risk factors and safeguards against CCHF.

In addition to these precautions, surveillance systems can be set up to watch for CCHF outbreaks and react swiftly to stop further viral spread.

Research and surveillance of crimean Congo hemorrhagic fever

Understanding the epidemiology and transmission of Crimean-Congo hemorrhagic fever (CCHF) is crucial for creating efficient prevention and control strategies.

Studies are being done to comprehend the virus's biochemistry, how it spreads, and how the immune system reacts to infection. As well as improving diagnostic techniques for the quick detection of the virus, this research can assist in discovering possible targets for the development of antiviral medications or vaccines.

Systems of surveillance are crucial for spotting CCHF outbreaks and tracking the virus's spread. These methods can include passive surveillance, where cases are reported to public health authorities, as well as active surveillance, when healthcare providers actively search for cases of CCHF. Monitoring animal populations for the presence of the virus is another form of surveillance.

Public health organisations can use surveillance data to pinpoint the locations where CCHF is most prevalent and focus their prevention and control initiatives there. Additionally, surveillance can be used to monitor CCHF epidemiological changes, such as modifications to the geographic distribution or viral transmission patterns.

Finally, it should be noted that Crimean-Congo hemorrhagic fever (CCHF) is a dangerous viral disease that can result in significant illness and even death in people. The virus is mostly spread by ticks and contact with infected animals, and places with these conditions may experience outbreaks.

To save ourselves and one another against the devastating impacts of infectious diseases, the entire human race must continue to support these initiatives and cooperate. Thus, we may contribute to making the world a safer and healthier place for everyone.
