Covid-19 Pandemic: 2020 Coronavirus outbreak
Broader definition of confirmed cases
On 12 February, the Hubei government adopted a broader definition of confirmed cases, which now includes clinically diagnosed patients diagnosed by their symptoms and CT scans but without a nucleic acid test, which can take days to process and delay treatment. "Using CT scans that reveal lung infection would help patients receive treatment as soon as possible and improve their chances of recovery," the provincial health commission said. This new methodology accounts for the sharp increase in Hubei's daily confirmed cases: 13,332 of the 14,840 newly confirmed cases in the province on 12 February were diagnosed clinically under the new definition.
