Shin Bambancin Mu yana da haɗari?

Tare da Mu a halin yanzu da aka jera a matsayin ɗayan bambance-bambancen ban sha'awa na WHO, ana iya fahimta idan kun ji rashin kwanciyar hankali. Amma yana da kyau a lura cewa, a halin yanzu, Cibiyar Kula da Cututtuka da Cututtuka ba ta lissafa Mu a ƙarƙashin bambance-bambancen ban sha'awa ko bambance-bambancen damuwa (wanda ya haɗa da bambance-bambancen, irin su Delta, waɗanda ke da shaidar haɓakar ƙwayar cuta, mafi munin cuta. , da rage tasiri a alluran rigakafi).

Amma game da kayan shafa na Mu, WHO ta lura cewa bambance-bambancen "yana da tarin maye gurbi wanda ke nuna yuwuwar kaddarorin tserewa na rigakafi." Wannan yana nufin cewa rigakafin da kuke da shi a halin yanzu (ko dai an samu ta allurar rigakafi ko rigakafin halitta bayan kamuwa da cutar) may ba zai yi tasiri ba idan aka kwatanta da nau'ikan da suka gabata ko asalin cutar ta SARS-CoV-2 (bambancin Alpha), saboda maye gurɓin da aka gano a cikin wannan nau'in, in ji Dokta Cherian.

(Kara karantawa: Me yasa Sabbin Cutar COVID-19 ke yaduwa da sauri?)

Dangane da tsananin Mu da yaduwarsa? Hukumar ta WHO tana "ci gaba da tattara bayanai da yawa, wanda zai tantance ikon bambance -bambancen da ke haifar da cutar da ta fi tsanani, ta kasance mai saurin yaduwa ko rage tasirin magunguna ko alluran rigakafi, wanda shine abin damuwa a yanzu" a cewar Dr. Cherian.

Har yanzu, yana sake nanatawa cewa "a ƙarshe, duk wannan ya dogara ne akan bayanan farko, kuma ana buƙatar ƙarin lokaci da bayanai don yin kowane tabbataccen bayani game da bambancin Mu." Ya yi wuri da wuri don sanin ko Mu zai zama babban abin damuwa ga Amurkawa masu cikakken allurar rigakafi.
