Chikungunya vs Dengue: How to Tell the Difference
Chikungunya and dengue both come from Aedes mosquitoes but differ in joint pain, risks and recovery. Learn the signs, tests and care in Bangladesh.

Sudden high fever, body pain, maybe a rash. In Bangladesh, the first worry is dengue. But another mosquito-borne virus causes very similar early symptoms: chikungunya. Chikungunya outbreaks have occurred in Bangladesh, and cases still appear.
Knowing the difference helps you understand what to watch for. Dengue can turn dangerous suddenly, while chikungunya is rarely fatal but can cause joint pain that lasts for months. This chikungunya vs dengue guide compares the two side by side.
Same Mosquito, Different Viruses
Both illnesses are spread by Aedes mosquitoes, mainly Aedes aegypti and Aedes albopictus. These mosquitoes:
- Bite mostly during the day
- Breed in clean, still water in containers around homes
- Are common in cities like Dhaka and Chattogram, especially during and after the monsoon
Because they share a mosquito, both can circulate at the same time. A person can even have both infections together, though this is less common.
Chikungunya vs Dengue: Side-by-Side
| Feature | Chikungunya | Dengue |
|---|---|---|
| Cause | Chikungunya virus | Dengue virus (4 types) |
| Time to symptoms | Usually 4–8 days (range 2–12) after bite (WHO) | Usually 4–10 days after bite (WHO) |
| Fever | Sudden, high | Sudden, high |
| Main pain | Severe joint pain, often in hands, wrists, ankles, both sides | Muscle and bone pain, pain behind the eyes, headache |
| Joint swelling | Common | Uncommon |
| Rash | Common | Common |
| Bleeding | Rare | Can occur (gums, nose, skin spots) |
| Shock / severe illness | Rare | Severe dengue can cause shock — a key risk |
| Platelets | Usually mildly affected | Often drop significantly |
| Long-term problems | Joint pain may last weeks to months or longer | Tiredness for weeks; joint pain usually settles |
| Specific treatment | None — symptom relief | None — fluids and monitoring |
These are general patterns. Symptoms overlap, and only a doctor with tests can confirm which one you have.
Chikungunya Symptoms in Detail
The name "chikungunya" comes from a word in the Kimakonde language meaning "to become contorted" — describing the bent posture of people with severe joint pain.
Common symptoms (WHO, CDC):
- Sudden fever
- Severe joint pain, often in several joints on both sides of the body
- Joint swelling
- Headache
- Muscle pain
- Rash
- Tiredness and nausea
Most people feel better within about a week. But the joint pain can continue or return for months, sometimes years, in some people.
Who is at higher risk of severe chikungunya?
According to the CDC: newborns infected around birth, adults over 65, and people with high blood pressure, diabetes or heart disease.
Example
Rashed, 52, in Dhaka has fever and wakes up unable to close his hands. His wrists, fingers and ankles are swollen and painful. He has no bleeding and is drinking well. His doctor suspects chikungunya but still checks for dengue, because both are circulating.
Why Dengue Needs Closer Watching
Dengue is usually the bigger short-term danger (see dengue symptoms and warning signs). Around the time the fever goes down, some people develop plasma leakage, which can lead to shock. The CDC says warning signs often appear 24–48 hours after fever ends.
Go to hospital immediately or call 999 for:
- Severe belly pain
- Vomiting 3+ times in 24 hours
- Bleeding from gums or nose, vomiting blood, black stools
- Extreme tiredness, restlessness or confusion
- Cold, clammy skin or very little urine
- Difficulty breathing
Because early chikungunya and dengue look alike, treat any fever in mosquito season as possible dengue until a doctor says otherwise. That means avoiding certain painkillers (see below).
How Are They Tested?
Your doctor chooses tests based on symptoms and how many days you have been ill:
- Dengue NS1 antigen — early in illness
- Dengue IgM/IgG — later in illness
- Chikungunya RT-PCR — early; availability may be limited
- Chikungunya IgM antibody — after the first several days
- CBC — platelets and haematocrit help assess dengue risk
Not every test is available in every lab. Ask your doctor what is needed and when.
Treatment and Home Care
There is no specific antiviral medicine for either virus. Care focuses on relieving symptoms and, for dengue, close monitoring (see dengue home care).
For both (in the early days)
- Rest
- Plenty of fluids — water, ORS, soup, dab water
- Paracetamol for fever and pain, at the correct dose
The painkiller rule
Avoid aspirin, ibuprofen and other NSAIDs until dengue has been ruled out. The WHO and CDC give this advice because NSAIDs can increase bleeding risk in dengue. Once a doctor confirms chikungunya and rules out dengue, they may consider other pain relief for persistent joint pain.
Managing chikungunya joint pain
- Gentle movement and stretching when the acute pain eases
- Cool compresses on swollen joints may help some people
- Avoid heavy physical work until joints recover
- If joint pain lasts for weeks, see a doctor — a medicine or physiotherapy plan may be needed
Do not take steroids or other strong medicines without a prescription.
Prevention: Protect Against Both
The same steps protect against dengue and chikungunya:
- Empty or cover all water containers at least once a week
- Check flower pot trays, AC trays, tyres, rooftop tanks and construction sites
- Use window and door screens
- Wear long sleeves and trousers, especially during the day
- Use mosquito repellent according to the label
- Use bed nets, including for daytime sleep
- Keep sick people under nets so mosquitoes do not spread the virus further
Frequently Asked Questions
What is the main difference between chikungunya and dengue?
Chikungunya usually causes severe, often long-lasting joint pain and swelling. Dengue more often causes pain behind the eyes, low platelets, and carries a risk of severe dengue with shock.
Is chikungunya more dangerous than dengue?
Chikungunya is rarely fatal, but joint pain can last a long time. Dengue is more likely to become life-threatening in the short term.
Can I have chikungunya and dengue at the same time?
It is possible, since the same mosquito spreads both. Your doctor may test for both.
How long does chikungunya joint pain last?
Most people improve in about a week, but some have joint pain for months or longer.
Can I take ibuprofen for chikungunya?
Not until dengue is ruled out. Use paracetamol and ask your doctor.
Can you get chikungunya twice?
Infection is generally thought to give long-term protection against chikungunya, but you can still get dengue.
Not Sure If It Is Dengue or Chikungunya? Ask a ShifaMate Doctor
If you have fever with body or joint pain and no warning signs, you can consult a verified doctor through ShifaMate. Describe which joints hurt, how many days you have had fever, and share photos of any rash or test reports. The doctor can suggest tests and safe pain relief. You can also browse ShifaMate doctors.
Warning signs of severe dengue mean hospital, not home.
