The diagnosis of the confirmed case should be based on the suspected case with any of the following pathological or serological evidence: (1) positive real-time PCR test for SARS-CoV-2; (2) sequencing of the entire viral genome showing strong homogeneity with known novel coronaviruses; (3) positive serological test for SARS-CoV-2 IgM and IgG antibody; or change in SARS-CoV-2 specific IgG antibody from negative to positive or increase in titer ≥ 4-fold in the recovery phase compared to that in the acute phase.
Upimaji wa kisa kilichothibitishwa unapaswa kutegemea kisa kukiwa na kisa kinachoshukiwa chenye kipengee chochote cha ushahidi wa ugnojwa au serolojia ifuatavyo: (1) kupatikaka kwa virusi vya SARS-CoV-2 kwa muda halisi kupitia vipimo vya PCR; (2)msururu mzima wa genome ya virusi unaoonyesha mfanano mkubwa na virusi vipya vya korona vinavyofahamika; (3)kuwepo kwa antibodi mahususi ya IgM na IgG kwa SARS-CoV-2 katika kipimo cha serami; au kubadilika kwa antibodi mahususi ya IgG ya SARS-CoV-2 kutokuwepo hadi kuwepo au kuongezeka kwa mara 4 na zaidi katika awamu ya kupona zaidi ya awamu ya hali mbaya ya ugonjwa.
