A virus originating from sloths and spread by midges has been detected in Europe for the first time, officials confirmed. The European Center for Disease Control (ECDC) reported 19 imported cases of the Oropouche virus in June and July. Spain had 12 cases, Italy five, and Germany two, according to the Manchester Evening News.

Also, The Lancet reported on July 25 that two deaths caused by Oropouche were recorded for the first time in Brazil. These involved two young women with no underlying health conditions.

The Oropouche virus (OROV) is a rapidly spreading arbovirus transmitted primarily by insects, particularly midges and mosquitoes. First identified in Trinidad in 1955, the virus has since become a significant public health concern in Central and South America, affecting hundreds of thousands of people. The virus is named after the Oropouche River in Trinidad, where it was initially discovered.

This illness caused by the virus, is similar in its presentation to dengue fever and can lead to large outbreaks, particularly in urban settings. Despite its prevalence, the virus remains relatively unknown outside the regions it directly affects.

Know the causes, symptoms, risk factors, prevention, and treatment of the Oropouche virus, whic is slowly emerging as a health threat.

Causes Of Oropouche Virus

The Oropouche virus is an RNA virus belonging to the family Peribunyaviridae. It is primarily transmitted to humans through the bite of an infected midge, specifically the Culicoides paraensis species. In some cases, mosquitoes, particularly the Culex species, have also been implicated in the transmission.

The virus has a zoonotic origin, with sloths and some bird species identified as potential reservoir hosts. The transmission cycle typically involves these animal hosts and the insect vectors, with humans becoming incidental hosts when bitten by an infected insect.

The rapid urbanization in tropical regions, combined with inadequate vector control measures, has facilitated the spread of the virus into densely populated areas. Unlike many other arboviruses, which are primarily confined to rural or forested regions, the Oropouche virus has shown a notable tendency to cause large-scale outbreaks in urban centers, making it a significant public health concern.

Symptoms Of Oropouche Virus

Oropouche fever, the illness caused by the Oropouche virus, typically manifests after an incubation period of 4 to 8 days following the bite of an infected insect. The symptoms are often sudden in onset and can resemble those of other viral infections, particularly dengue fever.

Common symptoms include:

1. High Fever: A sudden and intense fever is one of the hallmark symptoms of Oropouche fever. This fever can persist for several days, often accompanied by chills.
2. Headache: Severe headaches, often described as throbbing or pounding, are commonly reported by those infected.
3. Muscle and Joint Pain: Patients often experience significant muscle and joint pain, which can be debilitating and affect mobility.
4. Retro-orbital Pain: Pain behind the eyes is a specific symptom often associated with Oropouche virus infection.
5. Nausea and Vomiting: Gastrointestinal symptoms such as nausea and vomiting may occur, contributing to the overall discomfort.
6. Photophobia: Sensitivity to light, or photophobia, is a symptom that may develop, particularly during the acute phase of the illness.
7. Rash: A maculopapular rash, similar to that seen in other arboviral infections, may appear on the trunk and limbs.
8. Malaise and Fatigue: General feelings of malaise, extreme tiredness, and weakness are also common, sometimes persisting for weeks after the acute symptoms have resolved.

While Oropouche fever is generally not fatal, the symptoms can be severe and debilitating, leading to significant disruptions in daily life. In rare cases, complications such as meningitis or encephalitis may occur, particularly in individuals with weakened immune systems.

Risk Factors Of Oropouche Virus

Several factors can increase the risk of contracting the Oropouche virus:

1. Geographic Location: Living in or traveling to areas where the Oropouche virus is endemic, such as parts of Brazil, Peru, and Trinidad, significantly increases the risk of infection.
2. Seasonal Patterns: The risk of infection tends to be higher during the rainy season when insect vectors are more prevalent and active.
3. Urbanization: Rapid urbanization, particularly in tropical regions, can lead to increased human exposure to infected vectors, particularly in areas with poor sanitation and inadequate housing.
4. Outdoor Activities: Engaging in outdoor activities in endemic regions, especially in the evening or at night when insect vectors are most active, can increase the risk of bites and subsequent infection.
5. Lack of Vector Control: In regions where vector control measures are inadequate or ineffective, the population is at a higher risk of contracting the virus.

Prevention Of Oropouche Virus

Preventing Oropouche virus infection primarily involves reducing exposure to the insect vectors that transmit the virus. Key preventive measures include:

1. Use of Insect Repellents: Applying insect repellents containing DEET, picaridin, or oil of lemon eucalyptus on exposed skin can significantly reduce the risk of insect bites.
2. Protective Clothing: Wearing long-sleeved shirts, long pants, and socks can provide a physical barrier against insect bites.
3. Use of Bed Nets: Sleeping under insecticide-treated bed nets can offer protection, particularly in areas where insect vectors are prevalent.
4. Environmental Management: Reducing standing water around homes and communities, where insects breed, can help control the vector population.
5. Community Education: Raising awareness about the risks of the Oropouche virus and the importance of vector control can empower communities to take preventive actions.

Treatment Of Oropouche Virus Infection

Currently, there is no specific antiviral treatment for Oropouche virus infection. Management of the illness is primarily supportive and focuses on relieving symptoms. The main components of treatment include:

1. Hydration: Ensuring adequate fluid intake is crucial to prevent dehydration, particularly in cases with fever and vomiting.
2. Pain Relief: Over-the-counter pain relievers such as acetaminophen (paracetamol) can help alleviate headaches, muscle pain, and joint pain. It is important to avoid aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs) due to the potential risk of hemorrhagic complications.
3. Rest: Patients are advised to rest as much as possible to aid in recovery and reduce the severity of symptoms.
4. Medical Monitoring: In cases where complications arise, such as neurological symptoms, hospitalization and close medical monitoring may be required.
5. Management of Complications: If meningitis or encephalitis develops, more intensive medical interventions, including antiviral therapy and corticosteroids, may be necessary under a healthcare provider's guidance.

By taking proactive measures, both individuals and communities can reduce the risk of Oropouche virus infection and its associated complications.
