A lesser-known but more worrying insect-borne illness is the Oropouche virus, which is expanding outside of its typical tropical home. Two lives have been lost as a result of this concerning tendency, and a third death is being looked into. As a result, health officials have issued cautions to tourists from the United States.
The Oropouche virus is mostly spread by insect bites, and travelers visiting locations where the virus is common are advised by the Centers for Disease Control and Prevention (CDC) to take preventative measures against mosquito and midge bites on August 16. Here’s what you need know to keep yourself informed and secure.
Oropouche Virus: What Is It?
In 1955, the Oropouche hamlet in Trinidad was the site of the first discovery of the Oropouche virus. Mosquitoes and infected midges, or small flies, are the main vectors of infection. When these insects bite people, the virus can spread from animals like birds, rats, sloths, and monkeys to people.
The Oropouche virus is a less well-known disease than Zika or dengue, but it may still produce fever, headaches, joint discomfort, and rashes. More severe symptoms including light sensitivity, vertigo, and eye discomfort may appear in certain instances.
The virus is mostly restricted to tropical areas of the Caribbean, South and Central America, and Brazil. It also frequently causes outbreaks in the Amazon regions of Peru and Brazil. Since there is currently no vaccine or targeted therapy for Oropouche virus, tourists visiting these areas must take precautions.
Oropouche Virus Expanding to Novel Regions
The Oropouche virus is expanding outside of its usual range, according to recent statistics. In 2024, there was a notable increase in cases in Brazil, which has typically had the highest number. Bolivia and Cuba also reported instances for the first time, suggesting the virus is spreading to new areas.
A number of European countries have reported cases of viral infection among its travelers, including Germany, Italy, and Spain. The potential for future spread is highlighted by the international movement of sick persons, despite the fact that no local transmission has been observed in Europe. Eleven travel-related cases were recorded in the United States this year.
Experts surmise that one of the main causes of the virus’s spread may be climate change. The habitats of mosquitoes and other vectors are being impacted by changes in temperature and weather patterns, which is bringing them closer to humans and raising the risk of transmission.
Deaths Associated with the Oropouche Virus
The Oropouche virus has not been thought to be lethal in the past. But in 2024, two seemingly healthy young ladies in Brazil lost their lives to the virus. Though researchers caution that additional deaths may have happened in the past but were incorrectly ascribed to other mosquito-borne illnesses like dengue fever, these deaths mark the first fatalities directly connected to the Oropouche virus.
Investigations are ongoing into a third fatality that is considered to have been caused by the Oropouche virus, which raises questions about the virus’s ability to cause more serious illnesses than previously assumed.
Travel Advice and Prevention Advice from the CDC
The CDC released a travel alert on August 16 in response to the expanding threat, especially advising pregnant women to avoid non-essential travel to locations where Oropouche infections are occurring. The virus, like the Zika virus, which puts pregnant women at increased risk, has been connected to stillbirths and birth malformations.
It’s critical to take safety measures to prevent mosquito bites if visiting high-risk locations is inevitable. The Centers for Disease Control and Prevention (CDC) advises use EPA-approved insect repellents, dressing in long sleeves, and avoiding areas of standing water where midges and mosquitoes grow.
In order to keep bugs out of their houses and hotels, travelers need also make sure that the air conditioning or insect screens are installed. Strollers covered with mosquito nets can offer an additional layer of protection for parents taking little children on vacation.
Actions to Take in the Event of Symptoms
It’s crucial to see a doctor if you have been to a region where the Oropouche virus is known to be present and you begin to experience symptoms like fever, headaches, and joint discomfort. The Oropouche virus does not currently have a particular therapy, although early discovery and supportive care can help control symptoms and avoid complications.
To protect yourself and others, it’s critical to be educated and abide by health recommendations while the virus spreads. Travelers can lower their risk of illness and remain safe in impacted regions by exercising caution.
