Chikungunya Fever: A Growing Concern in Hong Kong and How to Protect Yourself

With the recent rise in Chikungunya fever cases in neighbouring regions, it's more important than ever for Hong Kong residents to be vigilant. This mosquito-borne illness, while not typically fatal, can cause severe and debilitating symptoms. At Rentokil Initial Hong Kong, we believe that awareness and proactive pest control are the best defences against this emerging health threat.

What is Chikungunya Fever?

Chikungunya fever is a viral disease transmitted to humans by infected mosquitoes. The name "Chikungunya" originates from the Kimakonde language, meaning "to become contorted," which aptly describes the severe joint pain that is a hallmark of the illness.

The primary vectors for Chikungunya are the Aedes aegypti and Aedes albopictus mosquitoes. While the Aedes aegypti is not found in Hong Kong, the Aedes albopictus, or Asian tiger mosquito, is common in our region. This is the same mosquito responsible for transmitting dengue fever.

Symptoms to Watch For

Symptoms of Chikungunya fever typically appear within three to seven days of being bitten by an infected mosquito. The most common signs include:

• Sudden high fever
• Severe and often debilitating joint pain, particularly in the hands and feet
• Muscle pain
• Headache
• Nausea
• Fatigue
• Rash

Most patients recover within a week, but for some, the joint pain can persist for months or even years. While complications are rare, the very young, the elderly, and those with underlying health conditions are at a higher risk of more severe illness.

The Chikungunya Situation in Hong Kong

While Hong Kong has not recorded any local cases of Chikungunya fever in recent years, the risk of imported cases is a significant concern. The recent outbreaks in nearby areas, coupled with frequent travel, increase the likelihood of the virus being introduced to the local mosquito population. The presence of the Aedes albopictus mosquito means that if an infected person is bitten by a local mosquito, a local transmission cycle could begin.

The Hong Kong government has already issued warnings and is stepping up mosquito control measures. However, individual and community-level efforts are crucial to prevent the spread of this disease.

Reducing Your Risk: A Proactive Approach

The most effective way to prevent Chikungunya fever is to avoid mosquito bites and eliminate their breeding grounds. Here are some essential steps you can take to protect yourself and your family:

Eliminate Mosquito Breeding Sites:

Aedes mosquitoes breed in stagnant water. Regularly check for and eliminate any standing water around your home and workplace. This includes:

• Flowerpot saucers
• Clogged gutters
• Old tyres
• Buckets and containers
• Air conditioner drip trays
• Any other items that can collect water

Personal Protection:

• Wear light-coloured, long-sleeved clothing and long trousers, especially during peak mosquito biting times (early morning and late afternoon)
• Use an effective insect repellent containing DEET, picaridin, or oil of lemon eucalyptus on exposed skin
• Install or repair screens on windows and doors to keep mosquitoes out
