Fifth disease ndi chimodzi mwazinthu zingapo zomwe zingawonetsere matenda a parvovirus B19. Fifth disease amapezeka kwambiri mwa ana.

Fifth disease imayamba ndi malungo otsika pang'ono (low‑grade fever), mutu, totupa, ndi zizindikiro zozizira, monga mphuno yothamanga kapena yodzaza. Zizindikirozi zimadutsa, ndiye patapita masiku angapo, zidzolo zimawonekera. Ziphuphu zofiira kwambiri zimawonekera pankhope, makamaka m'masaya. (zotero dzina lakuti “slapped‑cheek disease” (slapped‑cheek disease)). Kuwonjezera pa masaya ofiira, ana nthawi zambiri amakhala ndi zidzolo zofiira, zofiira za lacy (lacy rash) pa thupi lonse, makamaka pa manja, torso, ndi miyendo zomwe zimakhala zofala kwambiri.

Matendawa nthawi zambiri ndi wofatsa, koma amayi omwe ali ndi m'toto (pregnant women) mu trimester yoyamba wakhala zogwirizana hydrops fetalis, kuchititsa mowiriza padera.

Fifth disease, yomwe imadziwikanso kuti erythema infectiosum, ndi matenda a virus omwe amayamba ndi human parvovirus B19. Imafala kwambiri mwa ana, nthawi zambiri imakhudza omwe ali pakati pa zaka 4 mpaka 14. Zizindikiro nthawi zambiri zimayamba ndi kutentha thupi pang'ono, mutu, zizindikiro, komanso kumva ngati chimfine. Ana amatha kukhala ndi zidzolo zofiira pankhope (slapped cheeks), pamodzi ndi zidzolo pathupi, mikono, ndi miyendo. Akuluakulu, ululu m'manja ndi m'mapazi (joint aches). Makamaka, pafupifupi 20 mpaka 30 peresenti ya akuluakulu omwe ali ndi parvovirus B19 sangawonetse zizindikiro zilizonse.
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.

Chiwopsezo chopatsira (Fifth disease) parvovirus B19 kuchokera kwa mayi kupita kwa mwana ndi pafupifupi 33%, ndipo pafupifupi 3% ya ana omwe ali ndi kachilombo amakumana ndi zovuta. Mayi akatenga titile za immunoglobulin (IgM) ndi IgG asanakwane milungu 20 yoyembekezera, mwayi wa mavuto monga hemolysis, anemia, ndi hydrops fetalis (hydrops fetalis) kumawonjezeka. Kuti tiyambe kuthana ndi matendawa, tiyenera kuyang'ana ngati wodwalayo ali ndi parvovirus popeza titile za immunoglobulin (IgM) ndi IgG. Ngati titile za IgG sikuwoneka koma titile za IgM zikuwoneka, wodwalayo amafunika kuyang'anitsitsa nthawi yomwe ali pakati, kuphatikizapo ultrasound nthawi zonse kuti awone ngati pali vuto la hydrops fetalis kapena anemia la mwana.
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.
