Paravaccinia virus originates from livestock infected with bovine papular stomatitis. Erythema multiforme minus is sometimes divided into papular and vesiculobullous forms. The severity of symptoms vary, with dermatitis, pruritus and papular urticaria being common. Actinic prurigo is a rare sunlight-induced, pruritic, papular or nodular skin eruption. The first documented case of papular urticaria was caused by the larvae. Frequently, all three forms are regarded as papular mucinosis. This condition is characterized by a papular or vesicular reaction that is sometimes scabies-like. Occasionally such reactions are seen with more widespread papular eruptions. The initial macular lesions exhibit a papular, then vesicular and pustular appearance. Parapoxvirus is common, though rarely fatal; Infection causes papular and nodular lesions. Papular mucinosis is chronic and may be progressive. Livestock may not show symptoms of bovine papular stomatitis and still be infected and contagious. Papular urticaria has been suggested as developing in some people. The rash is composed of small papular lesions, each on a separate reddened base. Symptoms might include erythematous papular rash with scaling or inflamed patches on skin.
