The UK Health Security Agency (UKHSA) has issued a warning to holidaymakers heading to particular destinations after dozens of Brits have returned home carrying a grim infection.

The UK Health Security Agency (UKHSA) has issued an alert for travelers heading to specific destinations after several British citizens came back home infected with a concerning virus.

The initial signs of this infection often include a high fever and severe joint pain. Many affected individuals also experience muscle aches, headaches, sensitivity to light, and distinctive skin rashes.

While most people recover from the virus within one to two weeks, some may endure joint pain for a prolonged period, with up to 12% still feeling discomfort three years post-infection.

In a recent social media update on X, formerly known as Twitter, the UKHSA stated: “Planning a long-haul holiday this winter? Chikungunya, a mosquito-borne viral infection, is prevalent in countries like Thailand, Brazil, and India.”

Chikungunya is spread through the bite of infected Aedes mosquitoes, particularly Aedes aegypti and Aedes albopictus species.

Mosquitoes breed in natural and human-made sources of standing and stagnant water, such as blocked gutters and drains, litter, tarpaulins, open buckets, bins, plant pots and discarded items like tyres, and these are a risk factor for transmission if left around human habitation.

Unlike malaria-transmitting mosquitoes that come out at night, these insects remain most active throughout the day, particularly during dawn and dusk hours. This creates challenges for holidaymakers taking part in daytime activities.

Severe complications occur, though rarely, affecting roughly one in every 1,000 cases. Certain groups have higher risks, such as newborn babies, older adults, and people with pre-existing medical conditions.

Rare complications impacting the eyes, nervous system, heart, and digestive system have been reported.

There is no antiviral remedy for chikungunya, making prevention essential for holidaymakers. The most successful strategy involves thorough mosquito bite prevention tactics.

This includes applying repellents containing DEET or picardin to uncovered skin, and donning light-coloured, loose-fitting garments that protect arms and legs.

Application of insect repellents should follow the manufacturer’s guidelines, with particular attention required for infants and small children.

Holidaymakers should also be aware that these mosquitoes reproduce in stagnant water surrounding human dwellings. Steering clear of locations with natural and man-made water receptacles can help diminish exposure threats.

Unlike certain mosquito varieties that favour countryside locations, Aedes mosquitoes flourish in city environments and frequently bite inside buildings, making hotel room safeguards equally as important.
