Travelers' essential guide on Chikungunya vaccinations: key points to consider

In the latest updates on Chikungunya virus outbreaks, significant activity has been reported in tropical and subtropical regions, with major outbreaks occurring particularly in the Indian Ocean islands and parts of Asia.

Notable outbreaks include China's Southeast Coast, especially in Guangdong Province, where 478 confirmed cases were reported by mid-July 2025, mostly with mild symptoms. Despite ongoing outbreaks, no Chikungunya vaccine is currently available in China. However, vaccines are commercially available in other countries, such as the United States.

The Indian Ocean islands of Reunion, Mayotte, and Mauritius have reported major outbreaks, with over one-third of the population estimated to have been infected on Reunion Island in 2025. Mayotte had over 1,098 confirmed cases by late June 2025, prompting local emergency response measures to control the outbreak.

Sri Lanka, Kenya, Madagascar, Bolivia, Somalia, and other tropical/subtropical countries also remain areas with reported outbreaks or high risk.

Standard mosquito-bite prevention remains crucial in preventing Chikungunya infection. This includes using insect repellents containing at least 30% DEET (Diethyltoluamide), wearing long and light clothing, preferably treated with insect repellent, and eliminating mosquito breeding sites. Travelers to endemic areas are advised to follow vaccine recommendations if available, avoid mosquito bites especially during peak mosquito activity times, and be vigilant for symptoms after travel.

The World Health Organization (WHO) has issued warnings about the potential for a global Chikungunya epidemic in 2025, urging urgent action to prevent widespread transmission similar to the major outbreaks two decades ago. The virus is transmitted by *Aedes* mosquitoes and causes fever and severe joint pain, which can be debilitating and occasionally fatal.

Two Chikungunya vaccines are now approved in the EU. Vimkunya, a killed vaccine, can be used in all those aged 12 and older, while Ixchiq, a live vaccine, should only be used in the age range of 12 to 59 years. For both vaccines, a single dose is sufficient to achieve basic immunity.

Despite the ongoing outbreaks, Chikungunya has been "very rare" among German travelers so far, according to the Robert Koch Institute (RKI). However, the risk of Chikungunya infection increases significantly when traveling in areas with outbreaks. The Standing Committee on Vaccination (STIKO) has issued a recommendation for these vaccines, and vaccination is recommended for all those aged 12 and older planning a long stay (more than four weeks) or repeated short trips to endemic areas, especially if they have an increased risk of severe illness.

It is not recommended to rely on vaccination for protection if less than two weeks remain between vaccination and travel, according to the RKI online. To further protect against bites, travelers are advised to install screens on windows and doors, and use mosquito nets over their bed.

These updates highlight active transmission zones primarily in tropical/subtropical countries, with emphasis on vaccination where accessible and proactive vector control and personal protection methods to contain spread. The WHO has warned of a global spread of the Chikungunya virus, urging urgent preventive measures to avoid a major epidemic.

Science continues to analyze the effects of Chikungunya on various aspects of health-and-wellness, including workplaces and chronic-diseases.
Sleep patterns of infected individuals have shown disruptions due to the severe joint pain associated with the virus, leading to potential productivity losses in the manufacturing industry.
With medical-conditions like autoimmune-disorders and neurological-disorders, the impact of Chikungunya can be even more severe, necessitating careful consideration in policy-making and therapies-and-treatments.
Meanwhile, climate-change plays a role in the proliferation of mosquito populations, possibly exacerbating the spread of Chikungunya and other respiratory-conditions.
Digestive-health can also be affected when Chikungunya patients experience nausea, vomiting, and appetite loss.
Eye-health, hearing, and skin-conditions can potentially manifest indirectly, as a result of medication side-effects or prolonged illness.
Fitness-and-exercise can help strengthen the immune system and improve recovery, providing a positive approach to managing the Chikungunya virus.

Weight-management becomes essential for managing the overall health of individuals with Chikungunya, as maintaining a balanced diet (nutrition) contributes to the body's ability to fight off the virus.
Aging populations face greater risks from Chikungunya due to weakened immune systems, emphasizing the need for special focus in older adults' care.
Womens-health also requires an emphasis on evaluating the effects of the virus during pregnancy, delivery, and post-partum periods.
Mens-health is equally impacted, with men of all ages at risk and recommendations for vaccination where accessible.
Skin-care becomes essential to monitor for potential skin-conditions arising as a side-effect from the virus or medication.
Collaboration between the public and private sectors (industry) in the development of Chikungunya prevention, treatment, and vaccines is critical to combat this global health threat.
Medicare and insurance coverage play a crucial role in ensuring equal access to Chikungunya vaccines in the United States.
