Chikungunya

Chikungunya is a mosquito-borne viral infection that becomes more common during the monsoon due to an increase in mosquito breeding. It can hinder daily life and lead to unexpected medical expenses if not managed in time. Early detection plays a key role in ensuring timely care and preventing complications. Having the right health insurance plan helps cover diagnostic and treatment costs, making recovery more manageable financially.

Chikungunya is a viral disease caused by the chikungunya virus and transmitted to humans through the bite of infected Aedes mosquitoes. It is primarily found in tropical and subtropical regions, including India, where environmental conditions support mosquito breeding. The infection spreads when mosquitoes carry the virus from one infected person to another, making it a public health concern during outbreaks.

• It was first identified during an outbreak in Tanzania in 1952, and the name “chikungunya” comes from a local language meaning “to become contorted,” referring to joint pain.

• The primary carriers of the virus are Aedes aegypti and Aedes albopictus, which are active during the daytime, unlike many other mosquitoes.

• According to the World Health Organisation, chikungunya has been reported in over 110 countries across Asia, Africa, Europe, and the Americas.

• Globally, over 445,000 chikungunya cases and 155 deaths were reported across 40 countries in 2025.

• In India alone, 30,000+ suspected cases were reported in early 2025, with Maharashtra among the most affected states.

Chikungunya spreads through infected mosquito bites. Here's how it spreads:

• Chikungunya spreads through the bite of infected Aedes mosquitoes, mainly Aedes aegypti and Aedes albopictus.

• The virus is transmitted when a mosquito bites an infected person and then spreads it to others through subsequent bites.

• It does not spread directly from person to person through touch, air, water, or food.

• Transmission risk increases in areas with stagnant water, which serves as breeding grounds for mosquitoes.

• Warm and humid climates, especially during the monsoon, accelerate mosquito growth and virus spread.

• Aedes mosquitoes are daytime biters, increasing exposure during regular daily activities.

Several environmental and individual factors contribute to the spread of chikungunya:

• Mosquito exposure: Frequent exposure to mosquito bites, especially during the day.

• Stagnant water: Open containers, clogged drains, and water accumulation promote mosquito breeding.

• Travel to endemic areas: Visiting regions where chikungunya outbreaks are common increases risk.

• Urban living conditions: High population density and poor sanitation support mosquito spread.

• Weakened immunity: Individuals with low immunity are more vulnerable to infection.

• Age-related risk: Infants and older adults may face higher susceptibility.

• Pregnancy: Pregnant women may have increased health risks if infected.

• **Pre-existing medical conditions: Chronic illnesses can increase the chances of complications.

• Outdoor exposure: Spending time outdoors during the day raises the likelihood of mosquito bites.

The symptoms of Chikungunya are:

• Sudden onset of high fever

• Severe joint pain, especially in hands, wrists, ankles, and knees

• Muscle pain and body aches

• Headache and eye discomfort

• Skin rashes usually appear a few days after a fever

• Fatigue and weakness

• Nausea or vomiting in some cases

• Swelling in joints, leading to reduced mobility

• Joint pain that may persist for weeks or months even after recovery

Early and accurate diagnosis of chikungunya is important to differentiate it from other mosquito-borne infections and ensure proper management. Doctors rely on a combination of clinical evaluation and laboratory tests to confirm Chikungunya.

• Clinical evaluation:

Doctors assess symptoms, recent travel history, and exposure to mosquito-prone areas.

• Blood tests:

Used to detect the presence of the chikungunya virus in the body.

• RT-PCR test:

Identifies viral genetic material in the early stages of infection.

• Serological tests (IgM & IgG antibodies):

Detect antibodies produced in response to the infection, usually after a few days.

• Differential diagnosis:

Helps rule out similar infections like Dengue and Zika virus infection.

While chikungunya is rarely life-threatening, it can lead to prolonged and serious health complications in some cases.

• Chronic joint pain lasting for months or even years

• Joint swelling and stiffness, affecting mobility

• Neurological complications such as encephalitis (rare)

• Cardiovascular issues in severe cases

• Eye complications, including inflammation or vision problems

• Increased risk for newborns if infection occurs during pregnancy

• Worsening of existing medical conditions like diabetes or heart disease

• Persistent fatigue and weakness affecting daily life

There is no specific antiviral cure for chikungunya, so treatment focuses on relieving symptoms and supporting recovery.

• Pain relievers and fever reducers: Paracetamol (acetaminophen) is commonly used to manage fever and joint pain

• Non-steroidal anti-inflammatory drugs (NSAIDs): Ibuprofen or naproxen may be prescribed after ruling out dengue

• Hydration therapy: Oral fluids or IV fluids in severe cases to prevent dehydration

• Rest and supportive care: Adequate rest to help the body recover faster

• Physiotherapy: Recommended in cases of prolonged joint pain to restore mobility

Vaccines

IXCHIQ: A recently approved single-dose chikungunya vaccine (for adults in high-risk areas in some countries), though not yet widely available in India

Advanced/Supportive Treatments (in severe cases)

• Corticosteroids: May be used for persistent joint inflammation under medical supervision

• Disease-modifying anti-rheumatic drugs (DMARDs): In chronic cases with long-term joint issues

Preventing chikungunya mainly involves avoiding mosquito bites and reducing mosquito breeding in your surroundings:

• Get rid of mosquito breeding sites and avoid water from collecting in and around your home

• Keep your surroundings clean and hygienic to reduce the chances of mosquito growth

• Use mosquito repellents regularly to protect yourself from bites

• If your area has a high mosquito presence, wear full-sleeved clothes and cover yourself when stepping out during the day

• Use mosquito nets while sleeping and keep doors and windows properly closed

• If there is an outbreak in a place you plan to visit, consider postponing your travel

• Avoid stepping out unnecessarily, especially during the daytime when mosquitoes are most active

Chikungunya is typically covered under vector-borne disease coverage in health insurance policies, along with illnesses like dengue and malaria. Most comprehensive health plans in India include such infections, especially when hospitalisation or medical treatment is required.

• Hospitalisation expenses covered, including room rent, ICU charges, and doctor fees for chikungunya treatment

• Diagnostic tests covered, such as blood tests and lab investigations, are required for confirmation

• Pre and post-hospitalisation costs are typically covered for a fixed period before and after treatment

• Medicines and treatment costs, including consultations and prescribed drugs,s are included in most plans

• Cashless treatment facility available at network hospitals, reducing out-of-pocket expenses

• Lump sum benefit plans are available under specific vector-borne disease policies, where a fixed amount is paid on diagnosis, regardless of actual expenses

• Day care treatments and ambulance charges may also be covered depending on the policy

• Some insurers also offer dedicated vector-borne disease covers that specifically include chikungunya and provide either reimbursement of treatment costs or a fixed payout, helping manage sudden medical expenses during outbreaks.
