Definition

Viral arthritis is swelling and irritation (inflammation) of a joint caused by a viral infection.

Alternative Names

Infectious arthritis - viral

Causes

Arthritis may be a symptom of many virus-related illnesses. It usually disappears on its own without any lasting effects.

It may occur with infection by:

• Enterovirus
• Dengue virus
• Hepatitis B
• Hepatitis C
• Human immunodeficiency virus (HIV)
• Human parvovirus
• Mumps
• Rubella
• Alphaviruses, including chikungunya
• Cytomegalovirus
• Zika virus
• Adenovirus
• Epstein-Barr virus
• Ebola virus

Note: This list is not all inclusive.

It may also occur after immunization with the rubella vaccine, which is typically given to children.

While many people are infected with these viruses or receive the rubella vaccine, only a few people develop arthritis. No risk factors are known.

Symptoms

The main symptoms are joint pain and swelling of one or more joints.

Exams and Tests

A physical examination shows joint inflammation. A blood test for viruses may be performed. In some cases, a small amount of fluid may be removed from the affected joint to determine the cause of the inflammation.

Treatment

Your health care provider may prescribe pain medicines to relieve discomfort. You may also be prescribed anti-inflammatory medicines.

If joint inflammation is severe, aspiration of fluid from the affected joint may relieve pain.

Outlook (Prognosis)

The outcome is usually good. Most viral arthritis disappears within several days or weeks when the virus-related disease goes away.

When to Contact a Medical Professional

Contact your provider for an appointment if arthritis symptoms last longer than a few weeks.
