A virus that causes hemorrhagic fever was first detected in France this month in about 100 ticks collected during 2022 and 2023 on farms in the south of the country.
The Crimean-Congo hemorrhagic fever virus is usually spread through the bite of an infected Hyalomma tick, but there has yet to be a human infection in France.
Human cases of the virus have previously been reported in the Balkans, Spain, Russia and Turkey. Two cases, including one fatal, were reported during the summer in North Macedonia.
According to the World Health Organization (WHO), the virus can cause "severe outbreaks of viral hemorrhagic fevers," like Ebola, with a fatality rate of between 5 and 40 percent.
What is this type of virus?
A human can become infected with this virus through contact with infected ticks or animal blood from livestock such as cattle, sheep or goats. It can also be transmitted through person-to-person contact with infected blood or body fluids.
Symptoms of the virus are fever, dizziness, muscle aches, eye pain and sensitivity to light. A person may also experience vomiting, diarrhea and abdominal pain, according to the WHO.
Other signs include a fast heart rate, enlarged lymph nodes, and redness caused by bleeding.
