Ko te Fifth disease, e mohiotia ana ko te erythema infectiosum, he mate huaketo nā te parvovirus B19 tangata. Ka kaha ake i roto i ngā tamariki, ka pā ki te hunga kei waenga i te 4 ki te 14 tau. I te nuinga o te wā ka timata ngā tohu ki te kirikiri ngawari, ki te māhunga, ki te korokoro, me te āhua o te rewharewha.

I roto i ngā pakeke, ko te māuiui tuatahi he amuamu noa, tērā pea ka puta i ngā wiki i muri i te māuiui tuatahi. Ko te mea nui, tata ki te 20 ki te 30 % o ngā pakeke kua pangia e te parvovirus B19 kāore pea he tohu.
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.

Kei te 33 % te mōrea o te tuku parvovirus B19 mai i te whaea ki te pēpi, ā, 3 % o ngā wāhine kua pāngia e pā ki ngā raruraru i roto i ō rātou kohungahunga. Ka pāngia te whaea i mua i te 20 wiki o te haputanga, ka piki ake te tūpono o ngā raruraru pērā i te raruraru toto me te hanga wai i roto i te tinana o te pēpi. Hei timata i te whakahaere i tēnei mate, me tirotiro mēnā kua pā te mate ki te parvovirus mā te whakamātautau mō ētahi antibodies (IgM). Mēnā kāore he rongo o mua i te whakamātautau, engari ka tohu he mate nō tata nei, me aro turuki te manawanui i te wā e hapu ana, tae atu ki te tirotiro i te ultrasound mō ētahi take hauora o te pēpi.
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.
