Chinowanzozivikanwa sechirwere chechishanu, epidemic megalerythema, kana erythema infectiosum, chirwere chetachiona chinokonzerwa nehutachiona hwemunhu parvovirus B19, hutachiona hunobata vanhu chete. Kazhinji nyoro, inobatwa nenzira imwechete nevhairasi redzihwa. Iyo inoratidzirwa nekuonekwa kwekuputika, zviratidzo zvefuruwenza uye kurwadziwa kwemajoini. Chinangwa chekurapa ndechekubvisa zviratidzo.

Epidemic megalerythema, kana erythema infectiosum, chirwere chetachiona chinokonzerwa nemunhu parvovirus B19. Ichi chirwere chinotapukira, kazhinji chinyoro, chinowanzoitika mukupera kwechando uye kutanga kwechirimo, kazhinji sedenda renzvimbo, pakati pevana vadiki, kunyanya vane makore mashanu kusvika manomwe. Kunyange zvazvo 5% yezviitiko zvinowanikwa muvana vane makore mashanu kusvika kumakore gumi nemashanu, chirwere cheparvovirus B7 chinogona kukanganisa vana vaduku nevakuru. Inowanikwa pasi rose, inowanzoonekwa munyika dzine mwero. Zvinoratidzika zvakanyanya kuvasikana.

Parvovirus B19 chirwere chinowanzonzi chirwere chechishanu, sezvo chaiva chechishanu chechirwere chehuduku chinotapukira chinoratidzwa nekuputika kupiwa zita.

Parvovirus B19 yakatevedzana ichidaidzwa kuti SPLV yeSerum Parvovirus-Like Virus, HPV yeHuman Parvovirus uye B19 nemavara ekutanga anozivisa bhegi reropa payakatanga kuzivikanwa. Hutachiona hunobata vanhu chete.

Parvovirus B19 chirwere chinogona kutapurirwa nenzira yekufema. Inobatwa nenzira imwechete neiyo common cold virus, ne:

• kuisa minwe yavo kumuromo mushure mekubata munhu ane utachiona;
• kuisa minwe yake kumuromo mushure mekubata chinhu chine utachiona nemunhu ane utachiona;
• kufema madonhwe madiki ane utachiona hunobuditswa mumhepo nemunhu ane utachiona paanenge akosora kana kuhotsira..

Utachiona hunowanzopararira mukati mekutarisa kwakafanana. Munguva yedenda, vanhu vasina-immune vanobatwa nechirwere mu50% yezviitiko.

Utachiona hweParvovirus B19 hunogonawo kutapurirwa kubva kuna amai kuenda ku "fetus" panguva yekuzvitakura, kuburikidza ne placenta, izvo zvinogona kutungamirira kunonoka kufa kwe "fetus" kana kuti fetal anemia ine generalized edema (hydrops fetalis). Zvisinei, inenge hafu yevakadzi vane pamuviri haina kudzivirirwa kubva kuhutachiona hwekare. 

Pakupedzisira, chirwere ichi chinogonawo kutapurirwa kuburikidza neropa, kunyanya kuburikidza nekuwedzerwa ropa.

Zviratidzo nezviratidzo zvehutachiona hweparvovirus B19 zvinowanzoonekwa mazuva mana kusvika gumi nemana mushure mekuwana, dzimwe nguva kureba. 

Zviratidzo zvekutanga zvechirwere chechishanu zvinowanzovhiringidzika nevezvimwe zvirwere zvinotapukira zvakadai sechando. Vanonzwisisa:

• low fever;
• musoro;
• kuzara kwemhino;
• mhino inoyerera;
• kurwadziwa nemudumbu.

Mazuva akati wandei gare gare, kuputika kunoratidzika kunge kwakatsvuka kana kunosanganisira akasimudzwa dzvuku papules kana kutsvuka kwematama. Iyo mapundu inogona kupararira kumaoko, trunk, uye ipapo kune yese yemuviri, kazhinji isingabatanidzi tsoka dzetsoka uye zvanza zvemaoko. Kuputika kunowanikwa mu75% yevana uye 50% yevakuru. Inovava uye inoratidzwa nezvigamba zvitsvuku zvine mipendero yakaita semarashi, ayo anowedzerwa nekuratidzwa nechiedza chezuva.

Chero ani zvake ane utachiona hweparvovirus B19 anotapukira kwemazuva mashomanana izvi zvisati zvaitika. Nguva yekutapurirana inopera kana yangoonekwa. 

Kusimba kwezviratidzo kunosiyana pamunhu nemunhu. Mu50% yezviitiko, hutachiona hunoenda husingaonekwe kana kukanganiswa nekutonhora. Kazhinji yakapfava, inogona kuve yakakomba mune vamwe vanhu, kusanganisira:

• vana vane anemia kana sickle cell anemia;
• vanhu vane hosha dzakadai seAIDS, izvo zvinokanganisa simba regadziriro yomuviri yokurwisa hosha;
• vanhu vakuru;
• vakadzi vane pamuviri.

Muvana vane anemia, sickle cell anemia, kana zvirwere zvinoderedza masimba ezvirwere zvemuviri, parvovirus B19 inogona kukanganisa mapfupa emapfupa uye kukonzera anemia yakaoma.

Muvanhu vakuru, kuzvimba uye kurwadziwa kwakabatana (kwete-erosive arthritis) kunowanikwa mu70% yezviitiko. Aya maratidziro akabatanidzwa anonyanya kuwanda muvakadzi. Maoko, mawoko, zviziso zvemakumbo nemabvi ndizvo zvinonyanya kubatwa. Marwadzo aya anopera mumavhiki maviri kana matatu, asi anogona kuramba kana kudzoka kwemavhiki kana mwedzi kana makore.

Muvakadzi vane pamuviri, hutachiona hwekutanga hunogona kukonzera mu10% yezviitiko zve:

• kubvisa pamuviri kunongoerekana kwaitika;
• kufa kwe fetus;
• hydrops foeto-placental (kuwanda kweamniotic fluid mufetus extravascular compartment uye cavities) iyo inowanzoitika mukati mechikamu chechipiri chemimba;
• anemia yakaoma;
• fetal hydrops (fetus edema).

Ngozi yekufa kwe "fetus" i2-6% mushure mekutapukirwa kwaamai, ine njodzi yakanyanya mukati mehafu yekutanga yekuzvitakura.

Kuputika uye chirwere chose chinowanzogara mazuva 5-10. Mumavhiki mashoma anotevera, mapundu anogona kuonekazve kwenguva pfupi mushure mekusangana nezuva kana kupisa, kana nefivha, kushanda nesimba, kana kushushikana mupfungwa. Muvachiri kuyaruka, kurwadza kwemajoini kwakapfava uye kuzvimba kunogona kuramba kuripo kana kudzoka nguva nenguva kwemavhiki kana mwedzi.

Iko hakuna yekudzivirira parvovirus B19. Zvisinei, kana munhu achinge abatwa neutachiona uhwu, haakwanisi kutapukirwa nechirwere chemangwana kweupenyu hwose.

Iko hakuna zvakare kurapwa kwakananga kwehutachiona hweparvovirus B19. Chinangwa chekurapa ndechekubvisa zviratidzo.

Kusununguka kubva kufivha, kutemwa nemusoro uye kurwadza kwemajoini

Kurapwa kunokurudzirwa:

• paracetamol;
• nonsteroidal anti-inflammatory drugs (NSAIDs) yakadai se ibuprofen.

Kusununguka kubva pakukwenya kana kwakanyanya

Yakakurudzirwa mhinduro:

• cold compresses;
• colloidal oatmeal powder kuwedzera kumvura yekugeza;
• creams kana lotions.

Mamwe mazano

Zvinokurudzirwa zvakare kuti:

• inwai zvikuru;
• kupfeka chiedza, zvipfeko zvinyoro;
• dzivisa micheka yakaoma;
• kukurudzira kuzorora;
• kudzivisa kupisa kwakanyanya kana kutarisana nezuva, izvo zvinogona kukonzera kuipa kana kudzoka kweganda reganda;
• chengeta nzwara dzevana dziri pfupi uye dzakachena kana kutovaita kuti vapfeke magirovhosi usiku kudzivirira kukwenya.
