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.
Bacterial Pneumonia
Bacterial pneumonia is an infection of the lungs caused by bacteria. It can cause inflammation and fluid or pus in the air sacs, making breathing more difficult. Common symptoms include cough, fever, chills, chest discomfort, shortness of breath, fatigue, and sometimes mucus production. Severity varies from mild illness to a potentially serious infection requiring hospitalization.

InfectionDiagnosis
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.
Bacterial Pneumonia
Diagnosis is based on symptoms, physical examination, and assessment of breathing and vital signs. Chest imaging, usually a chest X-ray, can help identify lung infection. Blood tests and sputum testing may be used in selected cases to identify bacterial infection or assess severity. Additional testing may be needed for people who are severely ill, hospitalized, or at increased risk of complications.
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.
Bacterial Pneumonia
Good hand hygiene, avoiding tobacco smoke, maintaining recommended vaccinations, managing chronic medical conditions, and reducing exposure to respiratory infections can lower pneumonia risk. Staying up to date with recommended pneumococcal and influenza vaccination is particularly important for eligible people. People who are ill should follow appropriate respiratory hygiene and seek care when symptoms become severe.
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.
Bacterial Pneumonia
Risk is higher in older adults, young children, and people with weakened immune systems or chronic heart, lung, kidney, or metabolic conditions. Smoking, recent respiratory infection, hospitalization, aspiration risk, and close exposure to infected individuals may also increase risk. People living in healthcare or long-term-care settings can have additional exposure to certain bacterial pathogens.
