1 Name This is the Statement of Principles concerning herpes simplex (Reasonable Hypothesis) (No. 39 of 2018). 2 Commencement This instrument commences on 28 May 2018. 3 Authority This instrument is made under subsection 196B(2) of the Veterans' Entitlements Act 1986. 4 Revocation The Statement of Principles concerning herpes simplex No. 3 of 2010 made under subsection 196B(2) of the VEA is revoked. 5 Application This instrument applies to a claim to which section 120A of the VEA or section 338 of the Military Rehabilitation and Compensation Act 2004 applies. 6 Definitions The terms defined in the Schedule 1 - Dictionary have the meaning given when used in this instrument. 7 Kind of injury, disease or death to which this Statement of Principles relates (1) This Statement of Principles is about herpes simplex and death from herpes simplex. Meaning of herpes simplex (2) For the purposes of this Statement of Principles, herpes simplex means a clinical illness caused by herpes simplex virus type 1 (HSV-1) or herpes simplex virus type 2 (HSV-2). Lesions arising at an anatomical location where they have not previously occurred may be regarded as a new infection. Note 1: This infection is a lifelong, persistent infection of the peripheral nervous system ganglia. It is characterised by intermittent episodes of localised vesicular lesions on the skin or mucous membranes, but can also involve the central nervous system or other organs. Note 2: HSV-1 typically causes orofacial lesions and HSV-2 typically causes genital lesions, but either subtype may infect the oral mucosa or the genital tract and either may occur at other sites. Note 3: HSV complications include corneal scarring or significant skin scarring, eczema herpeticum, HSV dissemination or visceral involvement. Note 4: eczema herpeticum is defined in the Schedule 1 - Dictionary. (3) While herpes simplex attracts ICD‑10‑AM code B00 or A60, in applying this Statement of Principles the meaning of herpes simplex is that given in subsection (2). (4) For subsection (3), a reference to an ICD-10-AM code is a reference to the code assigned to a particular kind of injury or disease in The International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification (ICD-10-AM), Tenth Edition, effective date of 1 July 2017, copyrighted by the Independent Hospital Pricing Authority, ISBN 978-1-76007-296-4. Death from herpes simplex (5) For the purposes of this Statement of Principles, herpes simplex, in relation to a person, includes death from a terminal event or condition that was contributed to by the person's herpes simplex. Note: terminal event is defined in the Schedule 1 – Dictionary. 8 Basis for determining the factors The Repatriation Medical Authority is of the view that there is sound medical‑scientific evidence that indicates that herpes simplex and death from herpes simplex can be related to relevant service rendered by veterans, members of Peacekeeping Forces, or members of the Forces under the VEA, or members under the MRCA. Note: MRCA, relevant service and VEA are defined in the Schedule 1 – Dictionary. 9 Factors that must exist At least one of the following factors must as a minimum exist before it can be said that a reasonable hypothesis has been raised connecting herpes simplex or death from herpes simplex with the circumstances of a person's relevant service: (1) being exposed to HSV-1 or HSV-2 within the 30 days before the clinical onset of herpes simplex; Note: being exposed to HSV-1 or HSV-2 is defined in the Schedule 1 - Dictionary. (2) having a severe thermal burn within the 30 days before the clinical onset of herpes simplex; Note: severe thermal burn is defined in the Schedule 1 - Dictionary. (3) having a thermal or chemical burn within the seven days before the clinical onset of herpes simplex at or close to the site of the burn; Note: close to the site is defined in the Schedule 1 - Dictionary. (4) being in an immunocompromised state as specified at the time of the clinical onset of herpes simplex; Note: immunocompromised state as specified is defined in the Schedule 1 - Dictionary. (5) having surgery to nerve root ganglia within the 30 days before the clinical onset of herpes simplex, where the cutaneous distribution of herpes simplex corresponds with the nerve roots which were manipulated during surgery; (6) being exposed to sunlight or ultraviolet light at a level sufficient to induce at least mild erythema, within the seven days before the clinical onset of herpes simplex; (7) being pregnant at the time of the clinical onset of herpes simplex; (8) for acute herpes simplex encephalitis or acute herpes simplex retinal necrosis only, having surgery to the brain within the 30 days before the clinical onset of herpes simplex; (9) for orofacial herpes simplex only: (a) having surgery to the face within the 30 days before the clinical onset of herpes simplex; (b) having an upper respiratory tract infection within the seven days before the clinical onset of herpes simplex; or (c) having a fever of at least 39 degrees Celsius in the 72 hours before the clinical onset of herpes simplex; Note: surgery to the face is defined in the Schedule 1 - Dictionary. (10) for orofacial herpes simplex or genital herpes simplex only, having a category 2 stressor at the time of the clinical onset of herpes simplex; Note: category 2 stressor is defined in the Schedule 1 - Dictionary.

(12) for acute herpes simplex retinal necrosis of the eye only, having periocular trauma within the 30 days before the clinical onset of herpes simplex; (13) for herpes simplex of the eye only, having atopic dermatitis at the time of the clinical onset of herpes simplex; (14) for eczema herpeticum only: Note: eczema herpeticum is defined in the Schedule 1 - Dictionary. (a) having atopic dermatitis before the clinical onset of herpes simplex; or (b) having a specified dermatosis close to the site of the HSV-1 or HSV-2 infection, at the time of the clinical onset of herpes simplex; Note: close to the site and specified dermatosis are defined in the Schedule 1 - Dictionary. (15) for herpes simplex of the lip only: (a) having chapped lips in the 48 hours before the clinical onset of herpes simplex; or (b) playing a woodwind or brass musical instrument in the 48 hours before the clinical onset of herpes simplex; Note: chapped lips is defined in the Schedule 1 - Dictionary.
