Herpes Simplex

An acute infectious disease, characterised by the development of groups of super?cial vesicles, or blebs, in the skin and mucous membrane. It is due to either simplex type 1 or 2 virus, and infection can occur at any time from birth onwards; however the usual time for primary infection with type 1 is between the second and 15th year. Once an individual is infected, the virus persists in the body for the rest of their life. It is one of the causes of scrum-pox. Type 2 causes HERPES GENITALIS.

Symptoms Symptoms vary with the age of infection. In young infants, herpes simplex may cause a generalised infection which is sometimes fatal. In young children the infection is usually in the mouth, and this may be associated with enlargement of the glands in the neck, general irritability and fever. The condition usually settles in 7–10 days. In adults the vesicles may occur anywhere in the skin or mucous membranes: the more common sites are the lips, mouth and face, where they are known as cold sores. The vesicles may also appear on the genitalia (herpes genitalis) or in the conjunctiva or cornea of the EYE, and the brain may be infected, causing ENCEPHALITIS or MENINGITIS. The ?rst sign is the appearance of small painful swellings; these quickly develop into vesicles which contain clear ?uid and are surrounded by a reddened area of skin. Some people are particularly liable to recurrent attacks, and these often tend to be associated with some debilitating condition or infection, such as pneumonia.

Except in the case of herpes of the cornea, the eruption clears completely unless it becomes contaminated with some other organism. In the case of the cornea, there may be residual scarring, which may impair vision.

Treatment Aciclovir is e?ective both topically as cream or eye drops or orally. In severe systemic infections it can be given intravenously.... herpes simplex

Herpes, Genital

 Venereal disease. Caused by Herpes simplex virus, type 2, (HSV2) which infects the skin and mucosa of the genital organs and anus. The strain is more virulent than HSV1 which attacks face and lips. Contagious. STD. Blisters appear 4-7 days after coitus. May be transmitted by mother to baby at delivery. The condition is often misdiagnosed as thrush. To dispel doubts, refer to urological department of nearest hospital. Evidence exists between genital herpes and cancer of the cervix. Clinical diagnosis should be confirmed by virus culture. Attacks are recurrent and self-infective.

Symptoms: redness, soreness, itching followed by blisters on the penis or vulva. Blisters ulcerate before crusting over. Lesions on anus of homosexual men.

Treatment by general medical practitioner or hospital specialist.

Alternatives. Sarsaparilla, Echinacea, Chaparral and St John’s Wort often give dramatic relief to itching rash. See entry: ECHINACEA.

Tea. Formula. Equal parts: Clivers, Gotu Kola, Valerian. One heaped teaspoon to each cup boiling water; infuse 5-10 minutes. Dose: 1 cup thrice daily.

Decoction. Combine: Echinacea 2; Valerian 1; Jamaican Dogwood 1. One heaped teaspoon to each cup water gently simmered 20 minutes. Half-1 cup thrice daily.

Tablets/capsules. Poke root. Valerian. Passion flower. St John’s Wort. Echinacea. Chaparral. Pulsatilla. Red Clover.

Powders. Formula. Echinacea 2; Valerian 1; Jamaica Dogwood 1. Dose: 500mg (two 00 capsules or one- third teaspoon) thrice daily.

Tinctures. Formula. Echinacea 2; Sarsaparilla 1; Thuja quarter; Liquorice quarter. Dose: 1-2 teaspoons thrice daily.

Topical. Apply any of the following 3, 4 or more times daily. Pulp or gel of Aloe Vera, Houseleek, Echinacea lotion. Garlic – apply slice of fresh corm as an antihistamine. Yoghurt compresses (improved by pinch of Goldenseal powder). Zinc and Castor oil (impressive record). Apply direct or on tampons. Diet. Porridge oats, or muesli oats.

Supplementation: same as for Shingles.

Prevention. Women should be advised to submit for an annual cytosmear. Information. Herpes Association, 41 North Road, London N7 9DP, UK. Send SAE. ... herpes, genital

Coxsackie Viruses

A group of viruses so-called because they were ?rst isolated from two patients with a disease resembling paralytic POLIOMYELITIS, in the village of Coxsackie in New York State. Thirty distinct types have now been identi?ed. They constitute one of the three groups of viruses included in the family of ENTEROVIRUSES, and are divided into two groups: A and B. Despite the large number of types of group A virus (24) in existence, evidence of their role in causing human disease is limited. Some, however, cause aseptic MENINGITIS, non-specicifc upper respiratory infection and MYOCARDITIS, and others cause a condition known as HERPANGINA. HAND, FOOT AND MOUTH DISEASE is another disease caused by the A group. All six types of group B virus have been associated with outbreaks of aseptic meningitis, and they are also the cause of BORNHOLM DISEASE. Epidemics of type B2 infections tend to occur in alternate years. (See VIRUS.)... coxsackie viruses

Hepatitis Viruses

The most common causes of viral hepatitis are those caused by the Hepatitis A, B, C, D, E and G viruses. Hepatitis F virus has been described but is a doubtful entity. Other viruses which can cause hepatitis include the Epstein-Barr Virus, cytomegalovirus, and the Yellow Fever virus.... hepatitis viruses

Herpes Genitalis

An infection of the genitals (see GENITALIA) of either sex, caused by HERPES SIMPLEX virus type

2. It is mostly acquired as a result of sexual activity; some cases are caused by simplex type

1. After initial infection the virus lies latent in the dorsal nerve root ganglion (of the spinal cord) which enervates the affected area of the skin. Latent virus is never cured and reactivation results in either a recurrence of symptoms or in asymptomatic shedding of the virus which then infects a sexual partner. Around 30,000 cases of genital herpes are reported annually from clinics dealing with SEXUALLY TRANSMITTED DISEASES (STDS) in England, but there are also many unrecognised (by either patient or doctor) infections. Patients may have a history of painful attacks of ulceration of the genitals for many years before seeking medical advice. All patients with a ?rst episode of the infection should be given oral antiviral treatment, and those who suffer more than six attacks a year should be considered for suppressive antiviral treatment. ACICLOVIR, valaciclovir and famciclovir are all e?ective antiviral drugs. If a woman in the ?nal three months of her pregnancy contracts herpes genitalis, this can have serious consequences for the baby as he or she will be at risk of herpes encephalitis after delivery.... herpes genitalis

Papova Viruses

These include the human papilloma viruses (HPV), of which nearly a hundred strains have been identi?ed. HPV cause verrucae (see WARTS) on skin and, less often, on the mucous membranes of mouth, larynx, genitalia and the cervix. Some strains may predispose to eventual cancer.... papova viruses

Parainfluenza Viruses

These are included in the paramyxoviruses (see MYXOVIRUSES) and divided into four types, all of which cause infection of the respiratory system (see RESPIRATION). Infection with type 3 begins in May, reaches a maximum in July or August and returns to base-line level in October. Types 1 and 2 are predominantly winter viruses. Children are commonly affected and the manifestations include CROUP, fever, and a rash.... parainfluenza viruses

Picorna Viruses

These infectious agents derive their name from pico (small) and from RNA (because they contain ribonuleic acid). They are a group of viruses which includes the ENTEROVIRUSES and the RHINOVIRUSES.... picorna viruses

Herpes Gestationis

A rare skin disorder of pregnant women that produces crops of blisters on the legs and abdomen. The cause is not known.

Severe herpes gestationis is treated with corticosteroid drugs in tablet form and may require hospital admission.

The disorder usually clears up completely after birth of the baby, but tends to recur in subsequent pregnancies.... herpes gestationis

Viruses

The smallest known types of infectious agent. It is debatable whether viruses are truly living organisms or just collections of molecules capable of selfreplication under specific conditions. Their sole activity is to invade the cells of other organisms, which they then take over to make copies of themselves. Outside living cells, viruses are inert.

A single virus particle (virion) consists of an inner core of nucleic acid, which may be either DNA or RNA, surrounded

by 1 or 2 protective protein shells (capsids). Surrounding the outer capsid may be another layer, the viral envelope, which consists mainly of protein. The nucleic acid consists of a string of genes that contain coded instructions for making copies of the virus.

Common viral diseases include the common cold, influenza, and chickenpox (caused by the varicella–zoster virus). AIDS is caused by the human immunodeficiency virus (HIV).... viruses

Parainfluenza Viruses

a group of large RNA-containing viruses that cause infections of the respiratory tract producing mild influenza-like symptoms. They are included in the paramyxovirus group (see myxovirus).... parainfluenza viruses
