What to Expect During Your Exam

Exam Overview

To evaluate the nature, severity, and functional impact of malaria and any residual effects resulting from service-connected malarial infection, in order to assign an accurate disability rating under Diagnostic Code 6304 (38 CFR 4.88b).

What the examiner evaluates:

  • Confirmed diagnosis of malaria (Plasmodium species identification via blood smear, PCR, or other laboratory methods)
  • Active versus inactive disease status at time of examination
  • History and frequency of malarial attacks or relapses
  • Species of malaria parasite (P. vivax, P. falciparum, P. malariae, P. ovale) and implications for relapse potential
  • Severity and duration of febrile paroxysms (fever, chills, rigors)
  • Associated symptoms: profound fatigue, sweating, headache, myalgia, anemia, splenomegaly, hepatomegaly, nausea, vomiting
  • Complications: cerebral malaria, severe anemia, thrombocytopenia, renal impairment, pulmonary involvement
  • Treatment history and current antimalarial medications or prophylaxis
  • Residual conditions attributable to malaria (anemia, hepatic involvement, splenic enlargement, neurological sequelae)
  • Impact on daily functioning, occupational performance, and quality of life
  • Nexus between military service and current malaria diagnosis or residuals
  • Relevant laboratory and diagnostic test results supporting diagnosis

The exam will typically be conducted in person at a VA facility, contract exam site (e.g., LHI, QTC, VES), or via telehealth in some circumstances. Bring all relevant medical records, service treatment records showing deployments to malaria-endemic regions, and any private physician documentation. You have the right to request that the exam be recorded in most states - check your state's laws and notify the examiner in advance.

Typical duration: 30-45 minutes

Blood Smear Microscopy (Thick and Thin Smear)

Direct identification and species determination of Plasmodium parasites in peripheral blood; used to confirm active infection and assess parasite density.

What to expect:

A blood draw will be performed. The sample is examined under microscope. Results confirm active parasitemia, species, and approximate parasite load.

Key thresholds:

  • Positive blood smear with species identification — Supports active infection; critical for establishing diagnosis for rating purposes under DC 6304
  • Negative blood smear but prior positive documentation — Inactive disease status; rating based on frequency of prior attacks and residual symptoms

Tips:

  • Ensure prior positive smear results from service or post-service treatment are in your claims file before the exam.
  • If you have P. vivax or P. ovale, emphasize relapse history as these species form hypnozoite liver stages capable of causing recurring attacks years after initial infection.
  • Request that the examiner document the specific Plasmodium species identified, as this affects prognosis and relapse potential.

Pain considerations: Blood draw is minimally invasive. Alert the examiner to any vein access difficulties or prior complications from blood draws.

Rapid Diagnostic Test (RDT) / Malaria Antigen Test

Detects malaria-specific antigens (e.g., HRP-2 for P. falciparum, pLDH for other species) in blood as an alternative or adjunct to smear microscopy.

What to expect:

A fingerstick or venous blood sample is applied to a test strip. Results are available within 15-30 minutes. Often used when microscopy is unavailable or as a rapid screen.

Key thresholds:

  • Positive RDT — Supports active or recent infection; document species if determinable
  • Negative RDT with clinical history — Does not rule out inactive or previously treated infection; prior documentation remains relevant

Tips:

  • RDT results should be corroborated with smear or PCR for maximum diagnostic weight in your claims file.
  • A negative RDT does not invalidate your claim if service records or prior treatment records confirm the diagnosis.

Pain considerations: Fingerstick may cause brief discomfort. Inform the examiner if you have neuropathy or clotting concerns.

Polymerase Chain Reaction (PCR) Testing

Molecular detection and species typing of Plasmodium DNA in blood; most sensitive method, able to detect low-level parasitemia not visible on smear.

What to expect:

A blood sample is submitted to a laboratory for PCR analysis. Results may take several days. Not always performed at C&P exams but may be referenced from prior records.

Key thresholds:

  • Positive PCR with species identification — Highest sensitivity confirmation; strongly supports diagnosis and species-specific residual risk
  • PCR documented in service treatment records — Brings prior active infection into evidence record; supports nexus argument

Tips:

  • If PCR was performed during military service or at a DoD facility, request those records specifically and ensure they are in your VA claims file.
  • PCR is particularly important for P. vivax and P. ovale documentation due to relapse potential.

Pain considerations: Standard venipuncture; same considerations as blood smear collection.

Complete Blood Count (CBC)

Evaluates hemoglobin, hematocrit, red blood cell count (for malarial anemia), white blood cell count, and platelet count (thrombocytopenia is a hallmark of malaria).

What to expect:

Standard blood draw. Results reviewed for anemia, thrombocytopenia, and leukopenia - all common in active or recently active malaria.

Key thresholds:

  • Hemoglobin < 10 g/dL — Indicates significant anemia potentially ratable as a separate residual condition
  • Platelet count < 100,000/-L — Thrombocytopenia consistent with active or recent malaria; documents systemic involvement
  • Persistent anemia on multiple CBCs — Supports separate rating for malarial anemia as a residual condition

Tips:

  • Ensure the examiner documents any persistent anemia as a possible secondary condition to malaria.
  • Bring any prior CBC results showing anemia or thrombocytopenia during or immediately after malarial episodes.
  • Ask your primary care provider for a recent CBC to bring to the exam as supporting evidence.

Pain considerations: Standard venipuncture; alert examiner to any clotting disorders or anticoagulant medications.

Liver Function Tests (LFTs) / Hepatic Panel

Assesses hepatic involvement from malaria, including elevated AST, ALT, alkaline phosphatase, bilirubin - indicators of malarial hepatitis or hepatomegaly.

What to expect:

Blood draw with laboratory analysis. The examiner may review prior LFT results from your medical records rather than ordering new tests at the C&P exam.

Key thresholds:

  • Elevated bilirubin (> 2 mg/dL) — Indicates hemolysis or hepatic dysfunction attributable to malaria
  • Elevated transaminases (AST/ALT > 2x normal) — Supports hepatic involvement as a malarial residual

Tips:

  • If you have a history of jaundice or right upper quadrant pain after malarial episodes, explicitly describe this to the examiner.
  • Request that any hepatic residuals be evaluated as secondary conditions to malaria.

Pain considerations: Standard blood draw. No specific pain concerns beyond venipuncture.

Splenic Assessment (Physical Examination / Ultrasound)

Detects splenomegaly (enlarged spleen), a hallmark of malaria and chronic malarial infection. Hyperreactive malarial splenomegaly (HMS) is a recognized complication.

What to expect:

Physical palpation of the abdomen by the examiner to assess spleen size. May reference prior imaging studies (ultrasound, CT) from your records.

Key thresholds:

  • Spleen palpable below costal margin — Clinical evidence of splenomegaly supporting active or residual malarial disease
  • Ultrasound-confirmed splenomegaly (spleen > 12 cm) — Objective documentation of residual organ involvement from malaria

Tips:

  • If you have had prior imaging confirming splenomegaly, bring those reports to the exam.
  • Mention any left-sided abdominal discomfort, feelings of early satiety, or left shoulder pain (Kehr's sign) that could indicate splenic enlargement.
  • Splenomegaly may support rating for residual conditions beyond the primary malaria rating.

Pain considerations: Abdominal palpation may cause discomfort if spleen is enlarged. Tell the examiner if you experience pain during palpation and describe its severity and location accurately.

Estimate

Rating Criteria Breakdown

100% Active disease with severe, debilitating symptoms requiring ...

Active disease with severe, debilitating symptoms requiring ongoing treatment, or with serious systemic complications such as cerebral malaria, severe anemia (requiring transfusion), acute renal failure, or pulmonary edema. Veteran is essentially unable to maintain substantial gainful employment. Equivalent to a chronic, uncontrolled infectious process with major organ system involvement.

Key Symptoms

  • Continuous or near-continuous febrile episodes
  • Cerebral malaria with neurological deficits (altered mental status, seizures, focal deficits)
  • Severe hemolytic anemia requiring blood transfusions
  • Acute respiratory distress syndrome (ARDS) or pulmonary edema
  • Acute kidney injury or renal failure attributable to malaria
  • Profound and persistent debility preventing all normal activity
  • Hyperreactive malarial splenomegaly with massive organ enlargement
  • Multi-organ dysfunction syndrome

CFR: Under 38 CFR 4.88b DC 6304, a 100% rating reflects active malarial disease with incapacitating severity. The general policy under 38 CFR 4.88a directs that active infectious diseases be rated at 100% during active treatment, with rating reassessment after treatment completion based on residuals.

50% Moderately severe, active or frequently relapsing malaria wi ...

Moderately severe, active or frequently relapsing malaria with significant systemic symptoms. Veteran experiences recurring febrile paroxysms with substantial functional impairment between attacks. May include moderate anemia, hepatomegaly, or splenomegaly. Able to function but with significant limitation.

Key Symptoms

  • Recurring febrile paroxysms occurring multiple times per month
  • Significant fatigue and weakness persisting between episodes
  • Moderate anemia (hemoglobin 8-10 g/dL)
  • Palpable splenomegaly or hepatomegaly on examination
  • Persistent headaches, myalgias, and arthralgias between attacks
  • Nausea, vomiting, and gastrointestinal disturbance during paroxysms
  • Significant impact on work attendance and productivity
  • Ongoing need for antimalarial treatment

CFR: Under DC 6304, moderate to severe recurring malaria with systemic organ involvement and functional limitation corresponds to the 50% level. Frequent relapses (P. vivax or P. ovale) with documented parasitemia and systemic symptoms support this level.

10% Mild or infrequent malarial attacks, or inactive malaria wit ...

Mild or infrequent malarial attacks, or inactive malaria with minimal residual symptoms. Veteran may experience occasional relapses (fewer than once per year) or have only minor residual complaints such as mild fatigue, occasional headaches, or mild splenomegaly. Functional impairment is minimal.

Key Symptoms

  • Infrequent febrile episodes (fewer than 1-2 per year or in remission)
  • Mild residual fatigue not significantly affecting daily function
  • Minor hepatomegaly or splenomegaly on examination without significant symptoms
  • Mild, intermittent headaches
  • Occasional gastrointestinal symptoms
  • Malaria in inactive state with documented history of prior active disease
  • No current antimalarial treatment required

CFR: Under DC 6304 and general principles of 38 CFR 4.88b, a 10% rating reflects well-controlled, inactive, or minimally symptomatic malaria. Residuals that remain after successful treatment but cause some functional limitation are evaluated at this level. Note: Even inactive malaria can be rated based on documented history and residual organ effects.

How to Describe Your Symptoms

Febrile Paroxysms (Fever and Chills)

How to describe:

Describe the classic malarial fever cycle accurately: the onset of rigors (shaking chills), followed by high fever (often 103-105-F), followed by profuse sweating and resolution. Specify the frequency (daily, every 48 hours for P. vivax/ovale, every 72 hours for P. malariae), duration of each episode (typically 6-10 hours), and how incapacitating each episode is. Describe your worst episodes honestly.

Worst-day example:

“On my worst days, the chills hit so hard that I shake uncontrollably for 1-2 hours - I cannot hold a cup or type. The fever that follows reaches over 104-F and I am completely bedridden, confused, and unable to care for myself or my family. After the sweating phase, I am so exhausted I sleep for 12 hours and still feel weak the next day. These episodes have occurred [X] times in the past year.”

What the examiner listens for:

Cycle pattern of chills-fever-sweating, frequency of recurrence, degree of incapacitation during and between episodes, need for emergency care or hospitalization, effect on work attendance and family responsibilities.

Understatements to avoid:

Do not say 'just a fever' or minimize the cyclical pattern. Do not omit that you missed work, required bed rest, or needed someone to care for you during attacks. Do not fail to mention if you have gone to the ER or urgent care for malarial episodes.

Fatigue and Weakness Between Attacks

How to describe:

Accurately describe the inter-paroxysmal fatigue - the exhaustion that persists even when you do not have an active fever. Explain how this fatigue differs from normal tiredness: it limits your ability to work, exercise, care for your family, or complete daily tasks. Quantify it: 'I can only work 3-4 hours before I need to rest' or 'I cannot climb stairs without stopping.'

Worst-day example:

“Even on days without a full fever episode, I wake up feeling like I have not slept. I cannot complete a full workday - by noon I am so fatigued I have to lie down. I used to run 5 miles; now I cannot walk to the mailbox without feeling exhausted. This fatigue has cost me [X] sick days in the past year.”

What the examiner listens for:

Persistent fatigue not explained by other conditions, functional limitation on daily activities, impact on occupational capacity, need for rest periods during the day, inability to sustain physical or cognitive effort.

Understatements to avoid:

Do not say 'I get tired sometimes' without quantifying the severity. Do not minimize the difference between your pre-malaria energy levels and current state. Do not omit that fatigue affects your ability to work or function.

Relapses and Recurrences (P. vivax / P. ovale)

How to describe:

If your malaria is due to P. vivax or P. ovale, emphasize the relapse mechanism: these species form dormant liver stages (hypnozoites) that can reactivate months to years after initial infection, even after treatment. Describe each relapse episode, when it occurred, how it was treated, and whether relapses have continued or subsided. This ongoing relapse potential is critical to your rating.

Worst-day example:

“I was treated for malaria in [year] but had a full relapse in [year], [year], and [year] - each time requiring renewed antimalarial treatment. During my last relapse I was hospitalized for [X] days. I live with the constant anxiety that another relapse could occur at any time, which affects my ability to plan, work, and travel.”

What the examiner listens for:

Number and timing of documented relapses, treatment received for each relapse, whether the veteran has taken radical cure treatment (primaquine/tafenoquine for P. vivax), whether relapses continue to occur, and the functional and psychological impact of living with relapse risk.

Understatements to avoid:

Do not say malaria is 'cured' if you have P. vivax or P. ovale and have not confirmed eradication of liver-stage hypnozoites. Do not underreport relapses. Make sure each relapse episode is documented in your medical records.

Gastrointestinal Symptoms

How to describe:

Accurately describe nausea, vomiting, diarrhea, abdominal pain, and loss of appetite that occur during and between malarial episodes. Note if these symptoms are severe enough to prevent eating, require IV fluids, or result in significant weight loss.

Worst-day example:

“During my worst episodes, I vomited repeatedly for [X] hours and could not keep any food or water down. I lost [X] pounds during my acute illness. Even between fever episodes, I have chronic nausea that makes eating difficult and has contributed to ongoing weight loss.”

What the examiner listens for:

Frequency and severity of GI symptoms, documented weight loss, need for IV hydration or hospitalization, impact on nutritional status, and whether GI symptoms are attributable to malaria versus other conditions.

Understatements to avoid:

Do not minimize GI symptoms as 'just stomach issues.' Do not fail to mention significant weight loss or the need for IV fluids if applicable.

Neurological Sequelae (Post-Cerebral Malaria or Severe Disease)

How to describe:

If you experienced cerebral malaria or severe P. falciparum infection, describe any cognitive changes, memory impairment, concentration difficulties, mood changes, seizures, or focal neurological deficits that followed. These sequelae can persist long after the acute infection resolves and may be separately ratable.

Worst-day example:

“Since my episode of cerebral malaria in [year], I have difficulty concentrating at work, often losing my train of thought mid-sentence. My memory for recent events is significantly worse than before my illness. I had [X] seizures following my acute malaria episode, for which I take anticonvulsant medication.”

What the examiner listens for:

History of altered consciousness, seizures, or focal deficits during acute malaria; persistent cognitive or neurological complaints after recovery; impact on occupational and social functioning; current neurological medications.

Understatements to avoid:

Do not omit neurological complaints assuming they are unrelated to malaria. Explicitly connect any cognitive or neurological changes to your malarial illness timeline.

Impact on Daily Activities and Occupational Function

How to describe:

Describe specifically how malaria and its symptoms affect your ability to perform your job, maintain a household, care for dependents, participate in recreational activities, and maintain social relationships. Use concrete examples: missed work days, reduced hours, inability to meet physical job requirements, or having to change careers.

Worst-day example:

“In the past 12 months, I have missed [X] days of work due to malarial episodes or their after-effects. I was forced to reduce my hours from full-time to part-time and eventually had to leave my job as a [occupation] because I could not reliably perform the physical demands. I can no longer [specific activity] that I previously enjoyed.”

What the examiner listens for:

Specific occupational limitations, frequency of work absences, need to change jobs or reduce hours, inability to perform physical tasks, impact on family and social functioning, and whether the condition is getting better, worse, or staying the same.

Understatements to avoid:

Do not say 'I manage' or 'I get by' without explaining what accommodations or sacrifices you make to do so. Describe the full cost of managing your condition - rest periods, assistance from others, medications, and lifestyle restrictions.
