Gulf War Presumptive Conditions
The complete list under 38 CFR § 3.317 — MUCMI, undiagnosed illness, and infectious-disease presumptives for Southwest Asia and Afghanistan veterans.

★ At a Glance
Gulf War veterans who served in the Southwest Asia theater (Aug 2, 1990 – present) or Afghanistan (Sep 19, 2001 – present) may be presumed service-connected for three categories of conditions under 38 CFR § 3.317: medically unexplained chronic multisymptom illness (MUCMI), undiagnosed-illness symptom clusters, and a listed group of infectious diseases. This framework is separate from the PACT Act and often applies to the same veteran for different conditions.
Gulf War (§ 3.317) vs PACT Act (§ 1119) — Side by Side
These are the two presumptive frameworks most often confused. The biggest practical difference: § 3.317 covers symptoms without a diagnosis; the PACT Act covers specific named diagnoses.
| Feature | Gulf War (38 CFR § 3.317) | PACT Act (38 U.S.C. § 1119) |
|---|---|---|
| Statutory basis | 38 CFR § 3.317 (Persian Gulf War regulation) | Honoring Our PACT Act of 2022 (38 U.S.C. § 1119) |
| Service required | Southwest Asia theater (Aug 2, 1990 –); Afghanistan (Sep 19, 2001 –) | Burn-pit / airborne-hazard zones expanded under the Act (broader country list and dates) |
| Diagnosis required? | No — chronic symptoms qualify (undiagnosed illness pathway) | Yes — a specific named diagnosis is required |
| Typical conditions | Fibromyalgia, CFS, IBS / functional GI, chronic pain, chronic fatigue | Cancers, asthma, COPD, sinusitis, rhinitis, pulmonary fibrosis |
| Manifestation deadline | Dec 31, 2026 (subject to extension) | No sunset for most listed conditions |
| Can a veteran use both? | Yes — and many do. A Gulf War veteran with fibromyalgia and lung cancer would claim fibromyalgia under § 3.317 and lung cancer under the PACT Act. | |

Qualifying Service
- ★Southwest Asia theater (Aug 2, 1990 – present): Iraq, Kuwait, Saudi Arabia, Bahrain, Qatar, UAE, Oman, the Gulf of Aden, Gulf of Oman, Persian Gulf waters, Arabian Sea, Red Sea, and the airspace above any of these locations.
- ★Afghanistan (Sep 19, 2001 – present): added by later regulatory amendments.
- ★Service must have been on active duty in a qualifying location. Reservist and National Guard service counts if the veteran was on a qualifying period of active service.
MUCMI — Medically Unexplained Chronic Multisymptom Illness
Diagnosed conditions that lack a clear cause but have recognized symptom clusters. Service-connection is presumed for qualifying Gulf War veterans without needing a nexus opinion linking the diagnosis to a specific exposure.

Undiagnosed Illness — Symptom Clusters
Chronic symptoms (lasting 6+ months) that cannot be attributed to a known diagnosis. Symptoms must be at least 10% disabling and have manifested by December 31, 2026 (the current sunset date — periodically extended by Congress).
- Chronic fatigue (unexplained)
- Chronic skin signs or symptoms
- Chronic headache
- Chronic muscle pain
- Chronic joint pain
- Chronic neurological signs or symptoms
- Chronic neuropsychological signs or symptoms
- Chronic respiratory signs or symptoms (upper/lower)
- Chronic gastrointestinal signs or symptoms
- Chronic cardiovascular signs or symptoms
- Sleep disturbance
- Menstrual disorders (unexplained)
- Abnormal weight loss (unexplained)
Listed Infectious Diseases
Specific infectious diseases presumed service-connected when manifested to a degree of 10% or more during qualifying Southwest Asia service or within the regulatory timeframe afterward (38 CFR § 3.317(c)).
Evidence That Supports a § 3.317 Claim
- DD-214 or service records establishing qualifying Southwest Asia or Afghanistan service.
- Medical records documenting chronic symptoms (≥6 months) or the underlying MUCMI diagnosis (e.g. fibromyalgia, IBS, CFS).
- Lay statements from the veteran, family, or fellow service members describing onset, persistence, and functional impact. Lay evidence is particularly valuable for undiagnosed-illness claims.
- A treating provider's attempt at differential diagnosis — to demonstrate the symptoms cannot be attributed to a known cause.
- VA Form 21-526EZ as the application; symptom-specific DBQs are not required.
Common Pitfalls
- Assuming a diagnosis is needed — for the undiagnosed-illness pathway, the absence of a diagnosis is the whole point.
- Filing only one condition when multiple symptom clusters could each be rated separately (e.g. fibromyalgia + IBS + chronic headaches as three claims).
- Confusing the PACT Act with § 3.317 — and missing one because you assumed the other covered everything.
- Letting symptoms go undocumented for years — VA looks for evidence the condition is chronic and began during or near qualifying service.
- Overlooking § 3.317 conditions as a basis for TDIU when symptoms prevent substantially gainful employment.
