38 CFR § 4.88b lists Diagnostic Code 6329 as “Hemorrhagic fevers, including dengue, yellow fever, and others.” The code says to evaluate under the General Rating Formula for Infectious Diseases. The note’s examples are conditions of the central nervous system, liver, or kidney. Section 3.309(b) lists “Yellow fever.” It does not list dengue. It does not list hemorrhagic fevers as a separate name.

The rating criteria at each level

General Rating Formula for Infectious Diseases — DC 6329 says to evaluate under this formula

Rating %: 100

Criteria (verbatim). For active disease

Rating %: —

Criteria (verbatim). After active disease has resolved, rate at 0 percent for infection. Rate any residual disability of infection within the appropriate body system.

Rating %	Criteria (verbatim)
100	For active disease
—	After active disease has resolved, rate at 0 percent for infection. Rate any residual disability of infection within the appropriate body system.

Note: Rate under the appropriate body system any residual disability of infection, which includes, but is not limited to, conditions of the central nervous system, liver, or kidney.

DC 6329’s own row does not print a percentage. It says: “Evaluate under the General Rating Formula.” The second line of the General Rating Formula does not print a number in the rating column. The words “rate at 0 percent” are inside the criteria cell. The cell also says to rate any residual disability of infection within the appropriate body system. 38 CFR § 4.7 assigns the higher rating when the disability picture more nearly approximates the criteria required for that rating. Otherwise, the lower rating will be assigned. 38 CFR § 4.6 requires each element affecting the evidence to be studied so that decisions will be equitable and just.

The schedule title uses “including” before dengue, yellow fever, and others. The 2026-10-01 text does not print a separate yellow-fever code and does not name the diseases covered by “others.”

The opening note of § 4.88b says to rate any residual disability of infection within the appropriate body system as indicated by the notes in the evaluation criteria. It then says, as applicable, to consider the long-term health effects potentially associated with infectious diseases as listed in § 3.317(d), specifically Brucellosis, Campylobacter jejuni, Coxiella burnetii (Q fever), Malaria, Mycobacterium Tuberculosis, Nontyphoid Salmonella, Shigella, Visceral Leishmaniasis, and West Nile virus. Yellow fever and dengue are not in that list. DC 6304 is malaria, which is in the opening note and is a separate § 3.309(b) name.

What the words mean in your records

Yellow fever is one name inside the title

Section 3.309(b) says “Yellow fever.” The schedule title is “Hemorrhagic fevers, including dengue, yellow fever, and others.” Dengue is in the title. Dengue is not a § 3.309(b) name. The tropical-disease row for yellow fever points at DC 6329 because that is the schedule title that uses the words.

“And others” is not a list

The title ends with “and others.” The 2026-10-01 text does not name those other hemorrhagic fevers in the DC 6329 row. This page does not supply names the schedule does not print.

The residual examples are three systems

The note says conditions of the central nervous system, liver, or kidney. It says “including, but is not limited to.” It does not print a second percentage under DC 6329 for those conditions.

Evidence that speaks to each level

100 — for active disease

What the rater needs to see. Active disease under the formula. The schedule title is hemorrhagic fevers, including dengue, yellow fever, and others.

Where that usually lives. The record that describes the active disease and which fever was diagnosed.

Residuals

What the rater needs to see. A residual disability of infection. The note’s examples are conditions of the central nervous system, liver, or kidney.

Where that usually lives. The examination of that body system.

Level	What the rater needs to see	Where that usually lives
100 — for active disease	Active disease under the formula. The schedule title is hemorrhagic fevers, including dengue, yellow fever, and others.	The record that describes the active disease and which fever was diagnosed.
Residuals	A residual disability of infection. The note’s examples are conditions of the central nervous system, liver, or kidney.	The examination of that body system.

VA’s public DBQ list, checked October 5, 2026, names “Infectious Diseases (other than HIV-related illness chronic fatigue syndrome and tuberculosis)” under Infectious Diseases. The file is Infectious Diseases (other than HIV-related illness chronic fatigue syndrome and tuberculosis). The public list prints that title without commas between “HIV-related illness,” “chronic fatigue syndrome,” and “tuberculosis.”

The exam form

DC 6329 says to evaluate under the General Rating Formula and prints a residual note. This page does not say the form replaces those lines.

Related codes and how they interact

Malaria is a different tropical-disease code

DC 6304 is malaria. Section 3.309(b) lists malaria and yellow fever as separate names. DC 6329’s title includes yellow fever. It does not include malaria.

Secondary conditions and presumptions

38 CFR § 3.309(b) says the listed tropical diseases shall be granted service connection as a result of tropical service, although not otherwise established as incurred in service if manifested to a compensable degree within the applicable time limits under § 3.307 or § 3.308 following service in a period of war or following peacetime service, provided the rebuttable presumption provisions of § 3.307 are also satisfied. The paragraph also covers resultant disorders or diseases originating because of therapy administered in connection with such diseases or as a preventative thereof. “Yellow fever” is one of the names. Dengue is not.

38 CFR § 3.307(a)(4) says a tropical disease must have become manifest to a degree of 10 percent or more within 1 year from date of separation from service as specified in paragraph (a)(2), or at a time when standard accepted treatises indicate that the incubation period commenced during such service. 38 CFR § 3.307(a)(1) says the veteran must have served 90 days or more during a war period or after December 31, 1946. The same paragraph then says any period of service is sufficient for a specified disease under the conditions listed in § 3.309(c) and (e). That sentence does not name § 3.309(b). 38 CFR § 3.308(b) applies to a veteran of 6 months or more of peacetime service before January 1, 1947 who contracts a tropical disease listed in § 3.309(b). It uses “standard and accepted treatises.” Section 3.307(a)(4) uses “standard accepted treatises.” The text of § 3.308 does not print the disease name. It reaches the condition by naming a tropical disease listed in § 3.309(b).

Section 3.309(a) does not name yellow fever. Section 3.309(c) does not name it. The 2026-10-01 text of 38 CFR § 3.309(e) does not name yellow fever. 38 CFR § 3.309(f) does not name yellow fever. 38 CFR § 3.309(d) does not name yellow fever. 38 CFR § 3.320 does not name yellow fever. 38 CFR § 3.320a does not name yellow fever. 38 CFR § 3.320b does not name yellow fever. 38 CFR § 3.316 does not name yellow fever. 38 CFR § 3.317 does not name yellow fever. The same 2026-10-01 sections do not name dengue.

A separate question, when a presumption does not decide it, is a medical question on the facts under 38 CFR § 3.310. Paragraph (a) covers disability proximately due to or the result of a service-connected disease or injury. Paragraph (b) covers increase in severity and requires a medical baseline.

Short answers

What is the VA rating for DC 6329?

Under 38 CFR § 4.88b, hemorrhagic fevers, including dengue, yellow fever, and others, are evaluated under the General Rating Formula for Infectious Diseases. Active disease is 100 percent. Residuals are rated under the appropriate body system. Education only. VA decides on the evidence.

Where does § 3.309(b) place yellow fever?

On the tropical-disease list, under the time limits in § 3.307(a)(4) or § 3.308. The schedule code that uses the words is DC 6329, whose title is broader than yellow fever.

FAQ

How does VA rate DC 6329?

The code says to evaluate under the General Rating Formula for Infectious Diseases. Active disease is 100 percent. After active disease has resolved, the formula says to rate at 0 percent for the infection and to rate residuals under the appropriate body system. The note’s examples are central nervous system, liver, or kidney conditions. Education only.

Does the tropical list include every disease in the title?

Section 3.309(b) lists “Yellow fever.” The schedule title also names dengue and “others.” Dengue is not a § 3.309(b) name. The text does not list the diseases covered by “others.”

Is yellow fever on the herbicide or particulate-matter list?

The 2026-10-01 text of §§ 3.309(e), 3.309(f), 3.320, 3.320a, 3.320b, and 3.316 does not name yellow fever. Section 3.317 does not name it.
