Herpetotheriidae is an extinct family of metatherians. Although sometimes placed in the living opossum family (Didelphidae, as a subfamily Herpetotheriinae), they may form the sister clade to all living marsupials. Species of this family are generally reconstructed as terrestrial. Fossils of herpetotheriids come from North America, Asia, Europe, Africa, and perhaps South America. The oldest representative is Maastrichtidelphys from the latest Cretaceous (Maastrichtian) of the Netherlands and the youngest member is Amphiperatherium from the Middle Miocene of Europe.The family includes the following genera:Amphiperatherium (Early Eocene to Middle Miocene, Europe; synonyms: Oxygomphius, Microtarsioides, Ceciliolemur)Asiadidelphis (Late Eocene to Early Oligocene, Kazakhstan and Pakistan)Copedelphys (Late Eocene to Early Oligocene, North America)Entomacodon (Middle Eocene, North America; synonym: Centracodon)Golerdelphys (Late Paleocene, North America)Herpetotherium (Early Eocene to Middle Miocene, North America)Maastrichtidelphys (Maastrichtian, Europe)Nortedelphys (Lancian, North America)Peratherium (Early Eocene to Early Miocene, Europe; Early Oligocene, Africa; synonyms: Alacodon, Qatranitherium)Swaindelphys (Early Paleocene, North America)The following genera have been placed in the family, but their placement is disputed or obsolete:Garatherium (Early Eocene of Algeria) – possibly an adapisoriculid eutherianIndodelphis (Early Eocene of India) – originally referred to PeradectidaeJaegeria (Early Eocene of India) – a batRumiodon (Paleogene of Peru) – placement uncertain^ a b Asher et al. 2007, p. 318.^ Asher et al. 2007, p. 322.^ Martin et al. 2005, p. 497; Asher et al. 2007, p. 318.^ Mörs, von der Hocht & Wutzler 2000, p. 159.^ McKenna & Bell 1997, pp. 69–70.^ Crochet et al. 2007, pp. 634–635.^ Thomas E.

Herpes gladiatorum is one of the most infectious of herpes-caused diseases, and is transmissible by skin-to-skin contact. The disease was first described in the 1960s in the New England Journal of Medicine. It is caused by contagious infection with human herpes simplex virus type 1 (HSV-1), which more commonly causes oral herpes (cold sores).

Herpes gladiatorum is one of the most infectious of herpes-caused diseases, and is transmissible by skin-to-skin contact. The disease was first described in the 1960s in the New England Journal of Medicine. It is caused by contagious infection with human herpes simplex virus type 1 (HSV-1), which more commonly causes oral herpes (cold sores). Another strain, HSV-2 usually causes genital herpes, although the strains are very similar and either can cause herpes in any location.While the disease is commonly passed through normal human contact, it is strongly associated with contact sports—outbreaks in sporting clubs being relatively common. Other names for the disease are herpes rugbiorum or "scrumpox" (after rugby football), "wrestler's herpes" or "mat pox" (after wrestling). In one of the largest outbreaks ever among high-school wrestlers at a four-week intensive training camp, HSV was identified in 60 of 175 wrestlers. Lesions were on the head in 73 percent of the wrestlers, the extremities in 42 percent, and the trunk in 28 percent. Physical symptoms sometimes recur in the skin. Previous adolescent HSV-1 seroconversion would preclude most herpes gladiatorum, but being that stress and trauma are recognized triggers, such a person would be likely to infect others.

Herpes simplex virus 1 and 2 (HSV-1 and HSV-2), also known as human herpesvirus 1 and 2 (HHV-1 and HHV-2), are two members of the herpesvirus family, Herpesviridae, that infect humans. Both HSV-1 (which produces most cold sores) and HSV-2 (which produces most genital herpes) are ubiquitous and contagious.

Herpes simplex virus 1 and 2 (HSV-1 and HSV-2), also known as human herpesvirus 1 and 2 (HHV-1 and HHV-2), are two members of the herpesvirus family, Herpesviridae, that infect humans. Both HSV-1 (which produces most cold sores) and HSV-2 (which produces most genital herpes) are ubiquitous and contagious. They can be spread when an infected person is producing and shedding the virus.In simple terms, herpes simplex 1 is most commonly known as a "cold sore," while herpes simplex 2 is the one known by the public as "herpes," or "genital herpes." Herpes simplex 1 is known to infect about 95% of the human populace, and is treated less seriously than herpes simplex 2, even though both are incurable.Symptoms of herpes simplex virus infection include watery blisters in the skin or mucous membranes of the mouth, lips, nose or genitals. Lesions heal with a scab characteristic of herpetic disease. Sometimes, the viruses cause very mild or atypical symptoms during outbreaks. However, they can also cause more troublesome forms of herpes simplex. As neurotropic and neuroinvasive viruses, HSV-1 and -2 persist in the body by becoming latent and hiding from the immune system in the cell bodies of neurons. After the initial or primary infection, some infected people experience sporadic episodes of viral reactivation or outbreaks. In an outbreak, the virus in a nerve cell becomes active and is transported via the neuron's axon to the skin, where virus replication and shedding occur and cause new sores. It is one of the most common sexually transmitted infections.

Herpesviridae is a large family of DNA viruses that cause diseases in animals, including humans. The members of this family are also known as herpesviruses. The family name is derived from the Greek word herpein ("to creep"), referring to the latent, recurring infections typical of this group of viruses.

The family name is derived from the Greek word herpein ("to creep"), referring to the latent, recurring infections typical of this group of viruses. Herpesviridae can cause latent or lytic infections.At least five species of Herpesviridae – HSV-1 and HSV-2 (both of which can cause orolabial herpes and genital herpes), Varicella zoster virus (which causes chicken-pox and shingles), Epstein-Barr virus (which causes mononucleosis), and Cytomegalovirus – are extremely widespread among humans. More than 90% of adults have been infected with at least one of these, and a latent form of the virus remains in most people. In total, there are 9 herpesvirus types that infect humans: herpes simplex viruses 1 and 2 (HSV-1 and HSV-2), varicella-zoster virus (VZV), Epstein-Barr virus (EBV), human cytomegalovirus (HCMV), human herpesvirus 6A and 6B (HHV-6A and HHV-6B), human herpesvirus 7 (HHV-7), and Kaposi's sarcoma-associated herpesvirus (KSHV). There are more than 130 herpesviruses, and some are from mammals, birds, fish, reptiles, amphibians, and molluscs.
