Understanding Infectious Diseases & Immune Disorders Among Veterans
Your immune system serves as the body’s primary defense against illness but can be compromised or damaged through military service due to environmental exposures, chemical agents, stress, or infectious pathogens. Veterans exposed to certain deployment conditions or training environments may develop immune disorders, chronic infections, or nutritional deficiencies with lasting health impacts.
Medical evidence is the cornerstone of an accurate VA evaluation. Obtaining precise, comprehensive medical records and specialist documentation supports the evaluation of the true nature and severity of your health conditions.
Common Infectious Diseases & Immune Disorders: Medical Documentation Essentials
The Department of Veterans Affairs (VA) categorizes disabilities associated with infectious diseases, immune disorders, and nutritional deficiencies under 38 CFR Part 4 Subpart B – Infectious Diseases, Immune Disorders and Nutritional Deficiencies.
These conditions frequently identified by veterans include:
Chronic Fatigue Syndrome (CFS)
Medical Documentation Needed:
- Detailed notes confirming profound fatigue persisting at least 6 months, not improved by rest
- Clinical evaluations ruling out alternative explanations for fatigue (thyroid issues, anemia, infections)
- Documented symptoms such as post-exertional malaise, cognitive impairment, sore throat, and tender lymph nodes
- Records clearly indicating frequency and duration of incapacitating episodes
- Objective functional assessments stating impairment on daily tasks
Recommended Laboratory Tests:
- Complete Blood Count (CBC), Thyroid-stimulating Hormone (TSH), Erythrocyte Sedimentation Rate (ESR), Epstein-Barr Virus testing

Fibromyalgia
Medical Documentation Needed:
- Rheumatologist’s verified diagnosis meeting established criteria (pain duration, location, frequency)
- Documenting widespread musculoskeletal pain involving all body quadrants
- Records showing at least 11 of the 18 defined bilateral tender points
- Neuropsychological evaluations for cognitive (“fibro-fog”) symptoms
- Clear records of fatigue, sleep disturbances, and mood disorders included in symptoms
Recommended Diagnostic Assessments:
- Fibromyalgia Impact Questionnaire (FIQ)
- Tender point examination including location and severity documentation
- Sleep study results showing presence and quality of sleep disturbances
Autoimmune Diseases (Lupus, Rheumatoid Arthritis)
Medical Documentation Needed:
- Specialist evaluations documenting clear diagnostic criteria based on American College of Rheumatology standards
- Detailed symptom onset and progression timeline
- Laboratory tests confirming inflammation, immune markers (ANA, Anti-dsDNA, ESR, CRP), and organ involvement
- Reported involvement of specific organs and body systems with severity clearly assessed (e.g., joint erosions, renal impairment)
- Treatment history including medications used, responses, and side-effects
Recommended Laboratory Tests:
- Antinuclear Antibody (ANA), Rheumatoid Factor (RF), anti-CCP antibodies, specific inflammatory markers
- Imaging studies such as X-rays, MRI documenting joint or internal organ involvement
Gulf War-Related Illness
Medical Documentation Needed:
- Military records confirming service during the Gulf War period and related exposures
- Documentation excluding alternate diagnoses for the veteran’s symptoms
- Clear records of chronic multisymptom illness (fatigue, joint/muscle pain, cognitive difficulties, gastrointestinal issues)
- Date of symptom onset correlated to Gulf War service timeline

Essential Medical Documentation Checklist
The completeness and clarity of your medical records provide a foundation for accurate evaluations. Ensure medical documentation includes:
- Formal diagnosis clearly listed with official ICD-10 codes
- Comprehensive specialist evaluations documenting all symptoms, organ involvement, and functional impairment
- Detailed lab results specifically supporting diagnostic and clinical criteria
- Clear timeline for initial symptom onset, severity progression, and current health status
- Records of treatments used, effectiveness, and side effects experienced
- Frequency, duration, and severity of incapacitating episodes
- Documentation demonstrating functional impact on occupation and and daily life, including limitations, accommodations, and adjustments required
Common Secondary Conditions Associated with Infectious & Immune Disorders
Infectious diseases and immune disorders often lead to or exacerbate conditions in other body systems:
- Mental Health Disorders: Depression and anxiety frequently associated with chronic illness and unpredictable symptoms.
- Cognitive Impairment: Memory issues, reduced concentration, and mental fog can directly stem from immune disorders and chronic fatigue.
- Sleep Disorders: Chronic conditions often interfere significantly with sleep quality and duration.
- Gastrointestinal Disorders: IBS, inflammatory conditions, or malnutrition commonly linked to immune dysfunction.
- Neurological Conditions: Peripheral neuropathy, headaches, and other nervous system symptoms can be secondary to autoimmune or immune dysfunction conditions.
All secondary conditions should be clearly documented, demonstrating their direct relationship to your primary medical condition.
Examples of Medical Documentation: Weak vs. Strong
Chronic Fatigue Syndrome (CFS)
Weak:
“Veteran reports always being tired. Recommend rest and stress reduction.”
Strong:
“Veteran presents severe fatigue lasting over 24 months, unrelieved by rest, resulting in markedly restricted activity. Medical workup (CBC, CMP, ERS, sleep study) normal, ruling out alternative diagnoses. Meets CDC criteria with notable post-exertional malaise >24hrs, cognitive impairment confirmed by neuropsych evaluation (Sept 2023), persistent sore throat, tender lymph nodes. Documented 6 incapacitating episodes in past 12 months, each lasting over 3 days. Veteran unable to maintain full-time employment and reduced to part-time status with necessary accommodations due to unpredictable symptom patterns.”
Lupus (Systemic Lupus Erythematosus – SLE)
Weak:
“Veteran has lupus causing skin rash and joint pain. Continue prescribed treatment.”
Strong:
“Definitively diagnosed SLE (ANA positive 1:640 homogeneous pattern, anti-dsDNA positive). Current manifestations: inflammatory arthritis affecting multiple joints with significant functional impact and morning stiffness >1hr daily; recurrent documented pleurisy with chest CT confirming pleural effusion; mild renal involvement with proteinuria confirmed through urinalysis; consistent malar rash exacerbated by sunlight. Despite current treatment regimen (hydroxychloroquine, prednisone, mycophenolate mofetil) veteran experiences 4-6 annual flares, each incapacitating for multiple days and significantly affecting daily functions, employment capacity, and mobility.”
Understanding the VA Evaluation Process for These Conditions
When evaluating immune disorders or chronic infectious diseases, the VA generally conducts a comprehensive medical examination to assess all related symptoms, residuals, and functional impairments. VA-contracted medical examiners, specialized in these disorders, focus on:
- Confirming clinical diagnosis and associated diagnostic criteria
- Reviewing severity, frequency, and duration of incapacitating episodes
- Assessing functional impact on life, work, and physical capabilities
- Evaluating symptoms to determine total impairment accurately
Having thorough, specialized medical documentation prepared in advance allows the VA to assess more comprehensively and clearly.
Questions to Ask Your Healthcare Provider
To enhance detailed and accurate medical documentation, consider asking these questions during medical visits:
- “Can you clearly document the diagnostic criteria fulfilled for my condition?”
- “Could we record accurately the frequency, duration, and severity of my symptoms during flare-ups?”
- “Can you thoroughly document precisely how my condition limits my daily functionality and capacity to work consistently?”
- “Could you clearly record treatment regimens I’ve tried, including their effectiveness and any adverse effects?”
