What is Oropouche Virus?

Oropouche virus (OROV) is an arbovirus. It belongs to the Peribunyaviridae family. The virus is mainly transmitted by midges and mosquitoes. It causes Oropouche fever in humans. The illness is often mild but can be severe.

Origin and History

The virus was first isolated in 1955. It came from a blood sample in Trinidad. Since then, outbreaks have occurred in Brazil, Peru, and Panama. Over 500,000 cases have been reported. Most happen during rainy seasons.

How It Spreads

The primary vectors are Culicoides paraensis midges. Mosquitoes like Culex quinquefasciatus also spread it. These insects bite infected animals or humans. Then they pass the virus to new hosts. Outbreaks often follow seasonal patterns.

Symptoms of Oropouche Fever

Symptoms usually appear 3-8 days after a bite. They include sudden fever, headache, and muscle pain. Many people also experience chills and dizziness. Some may have nausea or vomiting. Symptoms typically last about a week.

Common Signs

• High fever (up to 104°F)
• Severe headache
• Muscle and joint pain
• Rash on trunk and limbs
• Photosensitivity (sensitivity to light)

When to Seek Help

Most cases resolve without treatment. But see a doctor if symptoms worsen. Warning signs include persistent vomiting or dehydration. Rare complications involve the central nervous system. Immediate care is crucial then.

Geographic Distribution and Risk Areas

Oropouche virus circulates in tropical regions of the Americas. Brazil reports the most cases. Peru, Panama, and Trinidad and Tobago are also affected. Outbreaks often occur in urban and rural areas. The Amazon basin is a hotspot.

Countries with Reported Cases

• Brazil (especially Amazonas and Pará states)
• Peru (Loreto region)
• Panama (Darien province)
• Trinidad and Tobago
• Bolivia (Beni department)

Travel Advisories

The CDC advises Level 1 precautions for travelers to affected areas. This means practice usual care. No travel restrictions are in place. But stay updated through CDC Travel Health Notices.

Prevention Strategies for Travelers

Preventing mosquito bites is key. Use insect repellent on exposed skin. Wear long sleeves and pants. Stay in accommodations with screens or air conditioning. Avoid outdoor activities during peak biting times.

Effective Repellents

Use EPA-registered repellents containing DEET, picaridin, or oil of lemon eucalyptus. Apply according to label instructions. Reapply after swimming or sweating. Treat clothing with permethrin for extra protection.

Environmental Controls

Eliminate standing water around your lodging. This includes flower pots, buckets, and discarded tires. Mosquitoes breed in stagnant water. Use bed nets if sleeping in open areas. Choose hotels with proper window screens.

Diagnosis and Treatment Options

Diagnosis requires laboratory testing. Blood tests can detect virus or antibodies. There is no specific antiviral treatment. Care focuses on relieving symptoms. Rest and hydration are important.

Medical Management

Use acetaminophen for fever and pain. Avoid aspirin due to bleeding risks. Drink plenty of fluids. Severe cases may require hospitalization. Most people recover fully within two weeks.

Seeking Medical Care Abroad

Know how to access healthcare at your destination. Travel health insurance is essential. Carry a list of local hospitals. The CDC offers guidance on finding medical care overseas.
