​Although Kawasaki Disease primarily affects children under five, adults can also be diagnosed—often after years of symptoms being misattributed or misunderstood. This page helps you understand the signs, challenges, and support available for adults living with or recovering from Kawasaki Disease.

​

❤️ Can Adults Get Kawasaki Disease?

Yes. While it’s rare, adult cases do occur. Some are diagnosed in their 20s, 30s, or even later. Others may only discover they had Kawasaki Disease in childhood after developing heart complications.

​

❤️ Symptoms of Kawasaki Disease in Adults

Symptoms may mirror childhood cases, including:

• Persistent fever (over 5 days)

• Rash across the body

• Conjunctivitis (red eyes) without discharge

• Swollen lymph nodes

• Red, cracked lips or tongue

• Swollen hands or feet / Peeling hands or feet

• Joint pain or inflammation 

Some adults may experience milder or atypical symptoms that lead to delayed diagnosis.

❤️ Diagnosis Challenges

Adult Kawasaki Disease is under-recognized and often misdiagnosed as:

• Viral infections

• Rheumatoid arthritis 

• Lupus

• COVID-19 or long COVID (in recent years)

A cardiologist may discover signs years later, such as coronary artery aneurysms during imaging.

​

❤️ Long-Term Complications

Adults may face:

• Heart valve issues

• Myocarditis

• Coronary artery aneurysms

• Chronic fatigue

• Mental health challenges
