Mosquito-Borne Virus Prompts Fresh Travel Warnings
Health authorities have urged holidaymakers to protect themselves against mosquito bites as outbreaks of chikungunya affect parts of the world. The US Centers for Disease Control and Prevention (CDC) has issued "level 2" notices for the Seychelles, Bolivia and Suriname, advising visitors to consider vaccination before departure. Pregnant people have been told to reconsider travel to affected areas because of the risk of severe illness in newborns.
Chikungunya is a viral infection spread through the bite of an infected mosquito and cannot pass directly between people. It is present in tropical and subtropical regions across the Americas, Africa, Asia and parts of Europe. The Pan American Health Organisation reported more than 502,000 cases and 186 related deaths across 41 countries or territories last year, with Brazil recording the highest number, followed by Bolivia, Argentina and Peru.
“This is a new situation for us. Until a very short time ago, we had no vaccine, and the only approach to prevention was to make careful use of insect repellents and insect precautions. So now we've got this extra tool in the armoury, and because the vaccine gives long-lasting protection, it’s something that could be considered if you are planning to travel over a period of time."
The UK Health Security Agency describes chikungunya as causing a sudden fever, usually accompanied by intense joint pain. Other symptoms may include swelling, muscle aches, headaches, nausea, fatigue and rashes. Most people get better without lasting effects, but joint pain may continue for weeks or even longer. Serious complications are rare, yet they can occur in older adults, newborn babies and people with existing medical conditions, and in some cases hospital care is needed.
What travellers should know
- Spread by infected mosquitoes in tropical and subtropical regions
- Not transmitted directly between people
- Sudden fever and joint pain are typical symptoms
- Vaccines available in the UK by prescription
- Bite prevention remains essential
The recent advisories show how quickly public health developments can affect travel decisions. Destinations such as the Seychelles and parts of South America are still accessible, but preparation matters more. Checking official advice, weighing up vaccination where appropriate and using reliable mosquito protection can reduce the chance of illness. With long-haul holidays already being planned, careful preparation carries as much importance as having valid documents and confirmed bookings.
