COVID-19 Daily Report and Data Analysis – February 12, 2020

Since the outbreak of COVID‑19, the total number of confirmed cases in China has continued to rise, reaching 59,804 by 24:00 on February 12, 2020, with 15,152 new confirmed cases reported on that day (including 13,332 clinically diagnosed cases in Hubei) and 2,807 new suspected cases.

On February 12, Hubei added a "clinical diagnosis" category to allow patients to receive standardized treatment earlier, which contributed to the apparent surge in confirmed cases.

National case‑fatality rate stood at 2.29% (Hubei 2.70%, Wuhan 5.58%). The report includes a breakdown of total confirmed, suspected, deaths, and recoveries, along with visual charts.

1. Trend of new confirmed and suspected cases nationwide – a sharp increase in confirmed cases driven mainly by Hubei, while suspected cases showed a decreasing trend.

2. Trend of new confirmed cases inside and outside Hubei – Hubei reported 14,840 new confirmed cases (including 13,332 clinical diagnoses), whereas provinces outside Hubei saw a decline to 312 new cases.

3. Ranking of key cities by new confirmed cases – Wuhan added 13,436 new cases; other major cities showed varying trends.

4. Overseas new confirmed cases – 46 cases were reported overseas, with slight decreases and no new affected countries.

5. Analysis of mortality and cure rates – mortality rates showed a slight decline while cure rates dropped for the first time since February 1.

6. Severe case mortality trend – severe mortality in Hubei rose to 18.49% after a brief decline; outside Hubei it rose to 6.03%.

7. Relationship between migration scale and confirmed cases (5‑day incubation) – migration peaks in early February correlated with subsequent case trends in Beijing, Guangzhou, Shanghai, and Shenzhen.

8. Infectivity activity coefficient – the coefficient surged in Hubei due to the inclusion of clinical diagnoses, while the rest of the country remained relatively stable.

9. Infection coefficient ranking – Jiangxi, Guangdong, and Zhejiang ranked highest; analysis links high infection rates to population mobility and travel during the Spring Festival.

The report also notes that mask and protective‑equipment production has recovered, public‑place access control measures were implemented in several provinces, and the government emphasized avoiding mass gatherings to curb cross‑infection.
