Post-chikungunya arthritis
The fever passes in days. For many people, the joint pain does not. Here is why it happens, how long it lasts, and when it needs a rheumatologist.

Chikungunya is a viral infection spread by Aedes mosquitoes — the same mosquitoes that spread dengue. It usually starts suddenly with high fever, a rash, and severe joint pain, often in the hands, wrists, ankles and feet on both sides. The word itself comes from a Makonde word describing someone bent over in pain.
The fever settles in a few days. The joint pain often does not. In many people it lasts weeks or months, and in some it becomes a long-term arthritis. This is called post-chikungunya arthritis (or chronic chikungunya arthritis), and it is one of the most common reasons people come to a rheumatology clinic after an outbreak in North India.
The three phases
| Phase | Timing | What usually happens |
|---|---|---|
| Acute | First 3 weeks | Fever, rash, severe joint pain and swelling, fatigue. The virus is active. |
| Post-acute | 3 weeks to 3 months | Fever has gone, but joint pain, stiffness and swelling continue or come and go. Wrist and finger tendon swelling is common. |
| Chronic | Beyond 3 months | Pain persists. In some it is inflammatory arthritis that needs disease-modifying treatment; in others it is non-inflammatory pain that improves with time and exercise. |
Who is more likely to have long-lasting joint pain
- People over about 40–45
- Those with very severe joint pain in the first weeks
- People who already had osteoarthritis or another joint problem
- Women are affected somewhat more often in many studies
Symptoms to recognise after the fever
- Pain and stiffness in the fingers, wrists, ankles, feet or knees — often both sides
- Morning stiffness lasting more than 30 minutes
- Swelling around the wrists and fingers, sometimes with tingling (carpal tunnel)
- Heel pain or pain where tendons attach
- Fatigue and poor sleep
- Pain that flares and settles in waves
How it is diagnosed
- Your history — a fever with severe joint pain during an outbreak is a strong clue
- Chikungunya blood tests — RT-PCR in the first week; IgM antibodies from about day 5 for a few months; IgG shows past infection
- ESR and CRP to measure inflammation
- Rheumatoid factor and anti-CCP — to look for rheumatoid arthritis, which can be unmasked or mimicked after chikungunya
- Ultrasound of the joints and tendons, which shows inflammation that may not be visible from outside
How it is treated
Treatment depends on the phase and on whether the arthritis is inflammatory:
| Phase | Usual approach |
|---|---|
| Acute | Rest, fluids and paracetamol. Avoid painkillers like ibuprofen, diclofenac and aspirin until dengue has been ruled out, because of bleeding risk. |
| Post-acute | Anti-inflammatory painkillers (NSAIDs) once dengue is excluded; gentle movement; sometimes a short course of low-dose steroids when pain is severe and NSAIDs are not enough. |
| Chronic inflammatory | Disease-modifying medicines — methotrexate has the most experience behind it; hydroxychloroquine or sulfasalazine are alternatives. Started and monitored by a rheumatologist. |
| Chronic non-inflammatory | Exercise, physiotherapy, pain management and time. Steroids and DMARDs do not help this type. |
Long courses of steroids, or repeated steroid injections from different sources, cause more harm than good. A clear plan from one doctor works best.
Approach based on the French Society of Infectious and Tropical Diseases 2014 guideline for chikungunya and subsequent experience in Indian rheumatology practice.
Prevention
- Prevent mosquito bites: repellent, full sleeves, nets, window screens
- Remove standing water around the home — coolers, pots, tyres, flower vases — where Aedes breed
- There is no routinely used chikungunya vaccine in India at present
