Dengue vs chikungunya: differences in symptoms, tests and treatment
Written & medically reviewed by Dr. Sanjay Anbu, MBBS · Last reviewed
Medically reviewedDengue and chikungunya are both viruses spread by the same Aedes mosquito, so they start in a very similar way with sudden fever and pain. Chikungunya is known for severe joint pain and swelling that can last weeks or months, while dengue carries a higher risk of bleeding and a dangerous drop in blood pressure. Blood tests confirm which one it is.
Side-by-side comparison
| Feature | Dengue | Chikungunya |
|---|---|---|
| Cause | Dengue virus, spread by the Aedes mosquito | Chikungunya virus, spread by the same Aedes mosquito |
| Typical symptoms | High fever, severe muscle and bone pain, pain behind the eyes, rash; platelets often fall | High fever with severe joint pain and swelling, often in hands, wrists, ankles and feet on both sides; rash; joints may be stiff |
| Onset & timing | Usually about 4 to 10 days after the bite | Usually about 3 to 7 days after the bite; joint pain may continue for weeks or months |
| Key tests | NS1 antigen early, dengue IgM/IgG later; CBC for platelets and haematocrit | Chikungunya RT-PCR in the first few days, IgM antibodies after about the first week; CBC |
| Treatment approach | Fluids, rest, fever control and monitoring for warning signs. Avoid ibuprofen and aspirin unless a doctor advises | Rest, fluids and pain relief as advised by a doctor; physiotherapy and gentle movement for long-lasting joint pain |
| Danger signs | Bleeding, severe belly pain, persistent vomiting, cold skin, drowsiness (severe dengue) | Severe illness is uncommon but newborns, older adults and people with other illnesses are at more risk; confusion or dehydration needs care |

How doctors tell them apart
- Where the pain is: joint pain and visible joint swelling point to chikungunya; deep muscle and bone pain with eye pain points to dengue.
- Platelet count: a marked fall is more typical of dengue.
- Timing of tests matters: NS1 or PCR early, antibody tests after several days.
- Because pain medicines like ibuprofen can be risky in dengue, doctors usually rule dengue out before recommending them.
See a doctor urgently if
- Bleeding from gums or nose, blood in vomit or stools
- Severe belly pain or repeated vomiting
- Drowsiness, confusion or restlessness
- Cold, clammy skin, fainting or very little urine
- Fever in a newborn, an elderly person or a pregnant woman near delivery
In an emergency, call your local emergency number (in India: 108 or 112).
Frequently asked questions
Can dengue and chikungunya happen together?
Yes. Because the same mosquito spreads both, co-infection is possible, and doctors sometimes test for both.
Why does chikungunya joint pain last so long?
In some people the virus triggers inflammation in the joints that continues after the fever has gone. It usually improves over weeks to months; a doctor can help with pain control and physiotherapy.
Is chikungunya more dangerous than dengue?
Chikungunya is painful but less often life-threatening. Dengue has a higher risk of severe complications such as bleeding and shock, so its warning signs need close watching.
Can I take painkillers for the fever?
Ask a doctor first. Medicines like ibuprofen and aspirin can increase bleeding risk if the illness turns out to be dengue.
