Overview

Rheumatoid Arthritis
Rheumatoid arthritis is a chronic autoimmune disease that primarily causes inflammation of the joints. The immune system mistakenly attacks tissues around the joints, leading to pain, swelling, stiffness and reduced movement. It often affects the hands, wrists and feet symmetrically, but can involve other joints and organs. Persistent inflammation can damage joints and affect overall health.
Avian Influenza
Avian influenza is an infection caused by influenza A viruses that primarily affect birds but can occasionally infect humans and other animals. Human infections are uncommon but can sometimes cause severe respiratory illness. Most human infections occur after close or prolonged contact with infected birds, animals, or contaminated environments.

Diagnosis

Rheumatoid Arthritis
Diagnosis is based on symptoms, physical examination, blood tests and imaging. Blood tests may measure rheumatoid factor and anti-CCP antibodies and assess inflammation. X-rays, ultrasound or MRI can show joint inflammation or damage. No single test confirms rheumatoid arthritis in every person, so the overall clinical picture is considered.
Avian Influenza
Diagnosis of avian influenza requires laboratory testing because symptoms can resemble other respiratory infections. Testing may involve molecular methods such as polymerase chain reaction on respiratory specimens. A detailed history of contact with birds, animals, contaminated environments, and relevant travel or outbreak exposure is important when evaluating possible infection.

Prevention

Rheumatoid Arthritis
Rheumatoid arthritis cannot always be prevented because genetic and immune factors contribute to its development. Avoiding tobacco use is an important way to reduce risk. Maintaining a healthy weight and addressing other modifiable health factors may also be beneficial. Early medical evaluation of persistent joint swelling and stiffness allows appropriate treatment to begin before significant joint damage develops.
Avian Influenza
Reducing contact with sick or dead birds and animals, avoiding contaminated environments, using appropriate protective equipment when exposure cannot be avoided, and practicing good hand hygiene can reduce risk. People working with poultry or infected animals should follow public-health and occupational infection-control guidance.

Risk Factors

Rheumatoid Arthritis
Risk factors include having certain genetic traits, being female, increasing age and having a family history of rheumatoid arthritis. Smoking is an important modifiable risk factor. Obesity and some environmental exposures may also contribute. The disease can occur in people without any known risk factor.
Avian Influenza
Risk is mainly associated with close or prolonged contact with infected birds or animals, contaminated environments, or surfaces containing infectious material. People working with poultry or other potentially infected animals may have greater exposure. Risk can vary according to the circulating virus and local animal infections.
