Fifth disease , tamén coñecido como eritema infeccioso, é unha infección viral causada polo parvovirus humano B19. É máis frecuente nos nenos, afectando normalmente a persoas de entre 4 e 14 anos. Os síntomas adoitan comezar cunha febre leve, dor de cabeza, dor de garganta e sentimentos similares á gripe. Os nenos poden desenvolver unha erupción vermella na cara que se asemella a slapped cheeks , xunto cunha erupción no corpo, brazos e pernas. Nos adultos, a dor nas articulacións é unha queixa común, que pode aparecer semanas despois da infección inicial. En particular, entre o 20 e o 30% dos adultos infectados co parvovirus B19 poden non presentar ningún síntoma.
Fifth disease (erythema infectiosum) is a viral infection caused by human parvovirus B19. It is more common in children than adults and usually affects children ages 4 to 14. The disease often starts with mild fever, headache, sore throat, and other flu-like symptoms. Children can also develop a bright red rash on the face that looks like “slapped cheeks”, along with a lacy or bumpy rash on the body, arms, and legs. In adults, joint aches are a common symptom. Rash and joint symptoms may develop several weeks after infection. About 20 to 30% of adults who are infected with parvovirus B19 will not have symptoms.

O risco de pasar parvovirus B19 de nai a bebé é de arredor do 33 %, e preto do 3 % das mulleres infectadas experimentan complicacións nos seus bebés. Cando a nai se infecta antes das 20 semanas de embarazo, aumentan as posibilidades de complicacións como problemas de sangue e acumulación de líquidos no corpo do bebé. Para comezar a xestionar esta enfermidade, debemos comprobar se o paciente estivo algunha vez exposto ao parvovirus mediante a proba de certos anticorpos (IgM) . Se a proba non mostra exposición pasada pero indica unha infección recente, a paciente necesita un seguimento estreito durante o embarazo, incluíndo ecografías regulares para comprobar se hai certos problemas de saúde do bebé.
The rate of vertical transmission during maternal parvovirus B19 infection is estimated at 33%, with fetal complications occurring in 3% of infected women. Fetal complications comprising hemolysis, anemia, and nonimmune hydrops fetalis and fetal loss are more frequent when maternal infection occurs before 20 weeks of gestation. The first step in the management of this patient would be to obtain immunoglobulin (Ig) M and IgG titres against parvovirus to evaluate if the patient has had previous immunity against the disease. If results are negative for IgG but positive for IgM (ie, primary infection), this patient would need close obstetrical monitoring for the following weeks, including serial ultrasounds to rule out fetal anemia and hydrops fetalis.

A quinta enfermidade (fifth disease) comeza cunha febre leve, dor de cabeza, erupción cutánea e síntomas parecidos ao resfriado, como secreción nasal ou confusión nasal. Estes síntomas pasan e, uns días despois, aparece a erupción cutánea. A erupción vermella brillante aparece máis comúnmente na cara, especialmente nas meixelas. (de aí o nome de "enfermidade das meixelas labazadas"). Ademais das meixelas vermellas, os nenos adoitan desenvolver unha erupción vermella e de encaixe no resto do corpo, sendo os brazos, o tronco e as pernas os lugares máis comúns.
A enfermidade adoita ser leve, pero nas mulleres embarazadas, a infección no primeiro trimestre relacionouse coa hidropesía fetal, causando un aborto espontáneo.

Non é necesario un tratamento específico xa que normalmente mellora co paso do tempo.
