Viral arthritis is an acute form of arthritis caused by a viral infection. According to a 2016 review in the journal Clinical Medicine, about 1% of acute arthritis cases are associated with a viral infection. Unlike osteoarthritis, in which symptoms are persistent, viral arthritis tends to come and go within a short span of time with no lasting after-effects.

Many viruses have been linked to viral arthritis. Treatments are generally directed at alleviating joint pain and inflammation. The resolution of the underlying infection will usually resolve the arthritis symptoms.

Symptoms of viral arthritis tend to develop suddenly, be of short duration, and not recur. Many cases of viral arthritis resolve within six weeks. The classic triad of symptoms are similar to those of rheumatoid arthritis:

  • Joint pain and stiffness, particularly in the morning
  • Loss of range of motion of a joint
  • Symmetrical joint involvement

The joint symptoms often are preceded by or coincide with the signs and symptoms of a viral infection (such as fever, muscle ache, and fatigue). In some cases, there may be a rash similar to that seen in rheumatic diseases.

Viral arthritis also tends to manifest with polyarthritis (arthritis in more than five joints). People with pre-existing osteoarthritis or rheumatoid arthritis may experience a worsening of joint symptoms due to the rapid onset of viral inflammation.

Viral arthritis does generally not cause joint destruction, although some viral causes (like the chikungunya virus) may cause joint pain for months and even years after the infection has cleared.


Viruses can sometimes invade a joint during an infection. When this occurs in the synovium or surrounding tissues, the viral particles are recognized as antigens (substances that trigger an immune response) by the immune system.

In such an event, the immune system will not only attacks the viruses freely circulating in the bloodstream but also deposits substances called immune complexes into the joint space. Immune complexes help defensive antibodies bind to antigens but also trigger acute inflammation, causing joint pain and swelling. Viral arthritis is the result.

The viruses most commonly linked to viral arthritis include:

Other viruses less commonly associated with viral arthritis include the hepatitis E virus (HEV), human T-lymphotropic virus type-1 (HTLV-1), enteroviruses, and the dengue virus.

Due to the widespread vaccination of mumps and other viral diseases, viral arthritis is less common in the United States than it once was.


Diagnosis of viral arthritis can be tricky because there is no single presentation of the disease that is considered "typical." The classic signs of viral arthritis—fever, rash, and joint pain—can occur with other illnesses, many of which are not viral.

Moreover, different viruses affect different organs and can manifest with a wide variety of symptoms. Viral arthritis caused by HBV, for example, can manifest with jaundice (yellowing of the eyes and skin), while viral arthritis caused by the rubella virus may present with a widespread rash.

Viral arthritis should be suspected if multiple joints on both sides of the body are affected, and the joint symptoms are accompanied by (or preceded by) symptoms of systemic infection.

Blood Tests

Viral arthritis is diagnosed with blood tests that confirm the underlying infection. These may include:

  • Antibody tests that detect disease-specific antibodies
  • Polymerase chain reaction (PCR) tests that detect disease-specific viral DNA
  • Immunoglobulin tests that measure the rise and fall of specific antibodies—known immunoglobulin M (IgM) and immunoglobulin G (IgG)—to help track the stage and duration of an infection

Depending on the suspected cause, these and other tests may be performed. Immunoglobulin tests are especially useful in directing the appropriate treatment based on whether the infection is acute (as indicated by an elevated IgM) or persistent (as indicated by a stable elevation of IgG).

Additional blood tests may also be ordered to rule out other possible causes for the joint symptoms. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels will be normal in OA but elevated in viral arthritis as well as inflammatory/immune arthritis, such as RA.


The treatment of viral arthritis focuses on symptom relief and the restoration of joint function. In some cases, treatments will be started presumptively since they are commonly used to treat many inflammatory joint conditions. Other prescription treatments may be delayed until more definitive results are obtained.

Treatment options for viral arthritis may include:

Corticosteroids are generally avoided since they can mask or worsen the underlying viral disease. Moreover, most cases of viral arthritis are self-limiting and resolve on their own in tandem with the underlying infection.

Physical therapy may help improve joint function in rare cases, like chikungunya infection, where joint symptoms are persistent.

A Word From Verywell

Viral arthritis is a frequently overlooked condition but one that can cause significant impairment and discomfort, particularly in people who already have arthritis. Early diagnosis can help doctors dispense the appropriate treatment so that you are neither undertreated nor overtreated.

If you suspect you have viral arthritis, you can seek a diagnosis from your primary care physician or ask for a referral to an orthopedist (who specializes in diseases of the muscles and joints) or a rheumatologist (who specializes in rheumatic diseases).
