Oropouche Virus Disease: A growing concern in Central and South America.
As of mid-2024, Central and South America are experiencing a significant outbreak of Oropouche virus disease, impacting countries such as Brazil, Bolivia, Colombia, Peru, and Cuba.
The Oropouche virus is primarily transmitted through the bites of infected midges (Culicoides paraensis) and mosquitoes. The virus is mainly spread in tropical and subtropical regions where these vectors are prevalent.
Symptoms of Oropouche virus disease include:
- sudden-onset fever,
- severe headaches,
- muscle and joint pain,
- rash,
- eye pain,
- nausea,
- and dizziness.
While most cases are mild and self-limiting, lasting 3 to 7 days, some individuals may experience more severe symptoms like meningitis and encephalitis.
There is no specific antiviral treatment or vaccine for the disease, so care focuses on symptom relief, such as rest, hydration, and pain management.
How to protect yourself from Oropouche virus
Preventing Oropouche virus disease involves reducing exposure to vector bites. Unlike mosquitoes, the main vector (midges) lacks a proboscis, and so is unable to bite through clothing.
Covering up, and wearing long-sleeved clothing, is therefore a keyway of preventing infective bites.
Other key measures include using plenty of insect repellent, impregnating clothing with Permethrin insecticide, using bed nets, and staying indoors during peak biting times.
Eliminating standing water where vectors breed is an important public health measure.
Prevention is key!
With no vaccine available, prevention remains the best defence against Oropouche virus disease.
Personal protective measures against insect bites also help protect against dengue, yellow fever, Zika, chikungunya, malaria, and a wide range of other tropical insect-borne infections, and should be followed carefully by travellers to tropical countries.
Cases found in Europe
Spain, Italy and Germany reported infections in numerous patients who had recently travelled to Cuba and Brazil.
The European Centre for Disease Prevention and Control (ECDC) warned of a moderate threat to travellers visiting Brazil, Bolivia, Colombia, Peru and Cuba, where Oropouche virus (Orov) is currently spreading.
If you’ve recently travelled to a known outbreak area and are experiencing any of the symptoms mentioned above, it is important to mention this to your doctor. This will help them rule out an Oropouche virus infection.
Worried about your upcoming travel plans?
Schedule a travel consultation with one of our specialist travel nurses.
They will guide you through potential health risks and recommend the necessary preventive measures and vaccinations to ensure your safety while travelling.

Bolivia is famous for its salt flats and varied terrain spanning over the Andes Mountains, the Atacama Desert and Amazon Basin rainforest. Located in South America, the climate varies drastically from one eco-region to the other. Travelling around Bolivia you’ll experience different climatic extremes, such as humid tropical climates to subtropical climates to desert-polar climates. It is important to seek travel advice before travelling as medical advice can vary dependent on the area/s you plan to visit.
Our general advice includes:
Vaccines
Routine immunisations are a high priority; it is good to check that they are all up-to-date before travelling anywhere. Given the current worldwide outbreaks, we strongly recommend checking your immunity status to measles. A simple immunity test can confirm all those who are unable to source vaccine proof. The best protection against measles is having 2 doses of a measles-containing vaccination, such as the MMR.
Travel vaccinations for Bolivia vary depending on where you plan to travel, and what you plan to do. It is best to book a consultation with a travel nurse to discuss your upcoming adventure. They will assess what risks you will potentially be exposed to. From this, they can develop a bespoke treatment plan specifically for your holiday.
As a minimum, travellers should be protected against Hepatitis A, and diphtheria, tetanus and polio. Certain travellers may consider vaccinations against typhoid, Rabies, Hepatitis B and Yellow Fever.
Yellow Fever
Yellow Fever is an unpleasant virus spread by the Aedes aegypti mosquito. This mosquito tends to bite during the day and is present in many lowland areas of South America and in all areas below 2,300m in Bolivia. Travellers who intend to visit the lowlands, such as the Chaco, Santa Cruz district and the Amazon may be advised to have the vaccine.
If your travel route includes other South American countries, you may also require the vaccination and an accompanying Yellow Fever Certificate in order to enter that country. The vaccination is not suitable for everybody. A careful risk assessment should be undertaken by a practitioner that specialises in the vaccine. Yellow Fever can only be given at designated Yellow Fever vaccination centres (YFVCs) – Fleet Street Clinic is a registered clinic.
Altitude
Bolivia is home to some of the highest peaks of the Andes mountains, with elevations of over 6,000m. The frequently visited cities of La Paz, Potosi and Uyuni all soar over 3,500m, making altitude sickness a real risk. The risk can be reduced by ensuring you stay hydrated, plan a slow ascent and factor in some acclimatisation days. Acetazolamide (Diamox) can be used to help aid the process. Book a pre-travel assessment and speak to a travel nurse about your options.
Insects
Mosquitoes, bugs and flies do more than just bite. They have the ability to transmit diseases that aren’t always preventable by vaccination or medication. Illnesses such as dengue fever, chikungunya, Zika, yellow fever, malaria and sleeping sickness are a few risks.
The best prevention is to entirely avoid mosquito bites. Cover up as much as possible and apply a minimum concentration of 50% DEET to any areas of exposed skin. Spraying your clothes with permethrin before travelling can provide extra protection. Sleep under a mosquito net, especially, if you plan to stay anywhere remote or rural.
See our Ultimate Bug Kit.
Malaria
Malaria occurs in the northern parts of Bolivia, in the Beni and Pando districts. Travellers heading to these areas should ensure they take anti-malarial medication. Mosquitoes that spread malaria are predominantly night-time biters. So, extra precautions should be taken between dusk and dawn. Any travellers who experience fever or flu-like symptoms on return from their trip should ensure they get tested for malaria, as unfortunately, no single prevention method is 100% effective.
First Aid
Whilst medical services and pharmacies are available in bigger cities, access to basic services is limited or even non-existent in the remote regions. Travel prepared and take a small medical kit that can treat basic complaints. Pack painkillers, antiseptic cream, plasters or dressing, and medication in case you suffer from an upset stomach. Head over to our online shop to purchase an essential first aid medical kit. This contains all your travelling medical essentials.
If you are prone to allergies, a non-drowsy antihistamine is helpful. Furthermore, if you take prescription medication, be sure to pack enough to last you for your entire trip.

Brazil: Yellow Fever
The incidence of Yellow Fever cases in Brazil has been increasing recently, with over 1000 cases of Yellow Fever in Brazil since July 2017. The cases were reported in Sao Paolo, Minas Gerais, Rio de Janeiro, Espiritu Santo and Distrito Federal.
As well as an increase in human cases of yellow fever, 738 cases of yellow fever virus in monkeys have been reported. Since the outbreak, several unvaccinated travellers have contracted yellow fever, and there has been at least one death. Due to the ongoing outbreak, travellers going to at risk areas of Brazil are advised to get the Yellow Fever vaccination.
In addition the World Health Organisation also advised travellers heading to the states of Parana, Santa Catarina and Rio Grande do Sul should receive the vaccination, irrespective of location.
What is Yellow Fever?
Yellow Fever is a flavirus found in the tropics of Africa and South America.
Monkeys are a natural carrier for the virus and it is spread between monkeys and humans via the bite of an aedes mosquito.
Illness: It causes an acute viral illness which has a 50% mortality rate.
Prevention: The yellow fever vaccination should be considered for travellers who are visiting a high risk area. A single vaccination affords life long protection. The vaccination many not be suitable for everyone, so ensure you seek a full travel consultation.
