Zvirwere zvinopararira zvakanyanya zviri nyore kuparadzirwa nemhepo, zvinyararire-muromo uye mumisha. Nokudaro, chero munhu akave achitaurirana nemunhu anorwara ane ORVI, zvinokosha kuziva nguva yekudzivirira nguva yefivha. Izvi zvichabatsira munguva yekutanga kudzivirira kana kurapa kwehutachiona, izvo zvichabatsira kukurumidza kupora kana kunyange kudzivirira utachiona.
Kubatanidzwa nguva yemukumbo kana gastric flu
Zita rakakodzera rechirwere chiri mubvunzo ndechirwere cherotavirus . Iko kusanganiswa kwekufema uye intestinal syndrome, inoparidzirwa nefecal-oral nzira.
Nguva yekudzidzira kwechimiro ichi cheAARVI pane zvikamu zviviri:
- Kurwara. Mushure mokupinda kwepathogen mumuviri, mavairasi anowedzera uye anopararira, kuunganidza mumucu membrane. Iyi nguva inotora maawa 24-48 uye, sekutonga, haisi kuteverwa chero zviratidzo.
- Prodromal syndrome. Iyi nharaunda haisi nguva dzose inowanzoitika (kazhinji chirwere chinotanga kupera), hachina mazuva anopfuura 2 uye inoratidzirwa nokushayiwa uye kushaya simba, kuora musoro, kupererwa kwechido, kugunun'una uye kushungurudzika zvishoma mumimba.
Nguva yekudzivirira nguva ye "nguruve" uye "chirwere chekurwara"
Utachiona hwehutachiona hunoputika hunoita hutachiwana hutachiona hwemukati kana gastric virus.
Nokuda kwe "nguruve" chirwere (H1N1), nguva yekuberekwa, kupararira uye kuunganidza masero emagetsi mumuviri inenge mazuva maviri kusvika ku5, zvichienderana nehutachiona hwehutachiona hwevanhu. Ivhareji inokosha mazuva matatu.
Mushure mekunge vatapukirwa nehutachiona hwemagwenga (H5N1, H7N9), zviratidzo zvinowoneka kunyange gare gare - mushure memazuva mashanu kusvika ku17. Maererano neO WHO statistics, nguva yekudzivirirwa kwechirwere ichi chirwere mazuva manomwe.
