Anxiety ! Climate change contributes to the spread of a deadly virus in Europe!

Climate change is causing significant changes in weather conditions, which have a direct impact on the habitats of some species. In this context, ticks carrying the CCHF virus migrate to more temperate regions, including Europe.

A study led by Ali Mirasimi, a virologist at the Karolinska Institute in Sweden, found that ticks migrate to the European continent due to longer and drier summers.

CHF Canada: silent bleeding – what are the modes of transmission?

CHF Canada, also known as CHF Canada, a very dangerous disease that is on the list of WHO priority pathogens due to its ability to cause epidemics and pandemics. The main symptoms are headache, high fever, joint pain, abdominal pain and vomiting. Jaundice and mood disorders may also appear. The disease is called “hemorrhagic” because of the severe consequences it has for patients, including bruising, nosebleeds, and skin hemorrhages.

The virus is spread by ticks of the Ixodidae family, such as Hyalomma ticks, which can transmit the disease to humans and other animals through biting and sucking. Except, the virus can also be transmitted through infected bodily fluids such as blood.

Global distribution of CCHF: from tropical countries to an emerging threat in Europe

With rising temperatures, these disease vectors are entering previously inaccessible regions, allowing the virus to spread. Cases have already been reported in Spain. and other European countries are likely to face the same problem soon.

However, it should be noted that, despite the concern caused by this geographical expansion, CCHF is already endemic in several countries in Africa, the Middle East, Central Asia and Eastern Europe. So far, these are mostly countries with a warmer climate than in most of Western, Central and Northern Europe.

List of countries where the disease is endemic includes the following African countries: Benin, Burkina Faso, Central African Republic, Democratic Republic of the Congo, Egypt, Ethiopia, Guinea, Kenya, Madagascar, Mauritania, Namibia, Nigeria, Senegal, South Africa, Sudan, Tanzania, Uganda and Zimbabwe. The list also includes several countries in the Middle East: Iran, Iraq, Oman, Saudi Arabia and the United Arab Emirates.

interesting to note that the disease is also endemic in various regions of China, India, Pakistan and Russia, as well as in the following countries of Central Asia: Azerbaijan, Kazakhstan, Kyrgyzstan, Tajikistan and Turkmenistan. Then come the countries of Eastern Europe. such as Albania, Armenia, Bosnia and Herzegovina, Bulgaria, Croatia, Georgia, Greece, Macedonia, Montenegro, Serbia, Slovenia, Turkey and Ukraine.

A therapeutic challenge and an urgent call for climate action

Although there is no specific treatment for CCHF, the antiviral drug ribavirin was used as a treatment option. However, the effectiveness of this drug remains controversial. Medical care provided to patients includes maintaining proper hydration, electrolyte monitoring and correction, oxygen administration and, if necessary, blood transfusion. Precautions are also necessary to avoid possible secondary bacterial infections.

The accelerated spread of HFCS in Europe calls for urgent action against climate change. Political and economic leaders are called upon to take effective action to curb pollution and reduce greenhouse gas emissions. Rising global temperatures and the spread of disease pose a serious threat to public health. If steps are not taken to address these issues, European countries will be increasingly at risk of epidemics and even a possible pandemic of the CCHF virus.
