Chikungunya Residuals

DC 6304Infectious Diseases38 CFR 4.88b, DC 6304

Lasting joint pain and stiffness after a chikungunya viral infection spread by mosquitoes. Many people develop chronic joint problems that last months or years after the initial infection clears.

How the VA rates this condition

The VA rates this condition based on how often symptoms occur and how severe each episode is. The examiner will ask about the frequency, duration, and intensity of your episodes, as well as how they affect your ability to work.

Diagnostic code

DC 6304

Rating range

0% – 60%

Rating levels

Rating criteria are defined in 38 CFR 4.88b, DC 6304. This guide presents a plain-language summary and is not a substitute for the full regulatory text. Always consult a VSO or VA-accredited attorney for case-specific advice.

Rating Levels

You have severe chronic joint disease from chikungunya with inflammatory arthritis, significant joint damage, or debilitating symptoms that prevent you from working full time.

What the VA looks for

Severe chronic inflammatory arthritis
Joint damage visible on imaging
Requires disease-modifying antirheumatic drugs
Major limitation of daily activities
Significant impact on employment

Common Pitfalls

⚠Not getting chikungunya serology during the acute phase — IgM antibodies are the best proof of recent infection, and they fade over time.
⚠Failing to document service in chikungunya-endemic areas — Southeast Asia, Africa, the Caribbean, and Central America are common exposure zones.
⚠Not distinguishing post-chikungunya arthritis from other causes — a rheumatologist opinion linking chronic joint symptoms to the documented infection strengthens your claim.
⚠Assuming joint pain will resolve on its own — up to 60% of chikungunya patients develop chronic joint symptoms that last years.
