In recent times, Chikungunya has become a major concern for the global healthcare community, particularly in tropical and subtropical regions where Aedes mosquitoes thrive.

On July 22, 2025, the World Health Organization (WHO) issued a warning regarding the rapid spread of Chikungunya, with large outbreaks reported in Indian Ocean islands and subsequent spread to parts of Africa, South Asia, and Europe. The disease is showing an increasing trend in several countries, especially in China. Although Vietnam has not recorded any community-acquired Chikungunya cases since the beginning of 2025, the current peak breeding season of Aedes mosquitoes (the vector of transmission) combined with high travel activity to and from Vietnam poses a significant risk of disease introduction and rapid community spread.

What is Chikungunya?

Chikungunya is an infectious disease caused by the Chikungunya virus, transmitted mainly through the bite of infected Aedes mosquitoes – the same vector responsible for dengue and Zika.

The name “Chikungunya” originates from the Kimakonde language in Africa, meaning “that which bends up,” describing the severe joint pain that forces patients into a stooped posture.

Common Symptoms

The illness usually begins 3–7 days after being bitten by an infected mosquito. Typical symptoms include:

·        Sudden high fever (often > 39°C)

·        Severe joint pain, which may persist for weeks or even months

·        Muscle pain, headache, and fatigue

·        Skin rash in some cases

It is important to note that Chikungunya symptoms can easily be mistaken for dengue fever. However, unlike dengue, Chikungunya rarely causes death, but it significantly impacts quality of life due to prolonged joint pain.

Is there a specific treatment available?

At present, there is no specific antiviral medication or vaccine for Chikungunya. Treatment is mainly supportive and aimed at relieving symptoms:

·        Pain relievers and fever reducers such as paracetamol, under medical supervision

·        Drink plenty of fluids to prevent dehydration.

·        Get adequate rest to help the body recover and reduce fatigue caused by the virus.

Effective Prevention

The most important preventive strategy remains mosquito control and bite prevention:

·        Sleep under mosquito nets and use repellents (creams or sprays)

·        Wear long-sleeved, breathable clothing

·        Maintain a clean environment: eliminate water containers, change vase water, introduce larva-eating fish

·        Apply insecticide spraying in outbreak areas

In addition, individuals traveling to or working in regions with rising Chikungunya cases should take proactive measures to avoid mosquito bites. Travelers should also monitor their health and promptly report to healthcare authorities if unusual symptoms appear (sudden high fever, joint pain, skin rash, etc.).
