Imbangela

I-COVID-19 ibangelwa ukutheleleka ngegciwane elinzima le-coronavirus 2 (SARS-CoV-2).

Ukwelapha

Akukho ukwelashwa okuqondile, okusebenzayo noma okwelapha isifo se-coronavirus 2019 (COVID-19), isifo esibangelwe yigciwane le-SARS-CoV-2. [183] [idinga ukuvuselelwa] [184] Ngakho-ke, itshe legumbi lokuphathwa kwe-COVID- 19 ukunakekelwa okusekelayo, okubandakanya ukwelashwa ukuqeda izimpawu, ukwelashwa okunamanzi, ukwesekwa komoya-mpilo nokuma okujwayelekile njengoba kudingeka, kanye nemithi noma amadivayisi wokusekela ezinye izitho ezibalulekile ezithintekile.

Ezinye Izilwane

Abantu babonakala bekwazi ukusabalalisa leli gciwane kwezinye izilwane, uhlobo lokudluliswa kwezifo olubizwa nge-zooanthroponosis.

Ezinye izilwane ezifuywayo, ikakhulukazi amakati nama-ferrets, zingalithola leli gciwane kubantu abanaleli gciwane. [] Izimpawu emakati zihlanganisa ukuphefumula (okufana nokukhwehlela) kanye nezimpawu zokugaya ukudla. [] Amakati angasabalalisa leli gciwane kwamanye amakati, futhi angakwazi ukusabalala igciwane liya kubantu, kepha ukudluliswa kwekati-kuya-kumuntu kwe-SARS-CoV-2 akukatholakali. Uma kuqhathaniswa namakati, izinja azisengozini yokungenwa yileli gciwane.Iziphathimandla ezandisa ubungozi bokudlulisa zibandakanya ukuqabula, ukukhotha, nokuphulula isilwane

Umlando

Leli gciwane kucatshangwa ukuthi lingokwemvelo futhi livela ezilwaneni, [] ngokutheleleka nge-spillover. [] Kunemibono eminingi yokuthi icala lokuqala (okuthiwa yi-patient zero) lavelaphi futhi uphenyo ngemvelaphi yalolu bhubhane luyaqhubeka. [] I-Phylogenetics ilinganisela ukuthi i-SARS-CoV-2 yavela ngo-Okthoba noma ngoNovemba 2019. [] Ukuhlaziywa kwe-phylogenetic algorithm kwaphakamisa ukuthi kungenzeka ukuthi leli gciwane lalizungeza eGuangdong ngaphambi kweWuhan. [] Yize olunye ucwaningo lwase-Italy luphakamisa ukuthi lwalukhona lapho ekuqaleni Septhemba 2019. [] Ubufakazi buphakamisa ukuthi yehla ku-coronavirus ehlasela amalulwane asendle, futhi isakaze kubantu ngokusebenzisa umphathi wezilwane zasendle ongumxhumanisi. [] Ithuba lokuthi leli gciwane likhishwe ngephutha elabhorethri nalo lisacatshangelwa ngokuqhubekayo. []
