Insights
This study analyzed COVID-19 epidemic features in Henan Province, China. The peak incidence occurred January 24-28, with Xinyang being a high-incidence area, and males and those with Hubei contact history being most affected.
Area of Science:
- Epidemiology
- Public Health
- Infectious Disease Dynamics
Background:
- Coronavirus disease 2019 (COVID-19) emerged as a global pandemic.
- Understanding regional epidemic characteristics is crucial for effective control strategies.
Purpose of the Study:
- To analyze the regional epidemic features of COVID-19 in Henan Province, China.
- To describe the time, population, and regional distribution of COVID-19 cases.
Main Methods:
- Statistical description and analysis of COVID-19 patient data and resident population.
- Analysis included time, population, and regional distribution of cases.
- Spatial autocorrelation analysis was performed.
Main Results:
- The cumulative incidence was 1.32/100,000, with a cure rate of 98.03% and fatality rate of 1.73% by March 9, 2020.
- The epidemic peak was January 24-28; Xinyang was the high-incidence area.
- Males, individuals aged 20-69, and those with a history of travel/contact with Hubei were disproportionately affected. Spatial distribution showed moderate clustering.
Conclusions:
- COVID-19 morbidity and mortality varied across Henan Province.
- The epidemic was characterized by local cases, male predominance, and a significant proportion with Hubei contact history.
- The spatial distribution of cases indicated moderate clustering, highlighting the need for targeted interventions.
Objectives:
To analyze the regional epidemic features of coronavirus disease 2019 (COVID-19) in Henan Province, China.
Methods:
According to the data of COVID-19 patients and the resident population at the end of 2018 in Henan Province, statistical description and analysis of epidemiological characteristics of COVID-19 in Henan Province were conducted, including the time distribution, population distribution, and regional distribution.
Results:
The cumulative incidence of COVID-19 in Henan Province was 1.32/100 000, the cure rate was 98.03%, and the fatality rate was 1.73% by March 9, 2020. The incidence curve showed that the epidemic peak reached from January 24 to January 28. The high-incidence area was Xinyang, with a standardized cumulative incidence rate of 4.36/100 000. There were 580 female COVID-19 patients (45.60%), 688 males (54.09%) in Henan Province. The incidence of males was 1.41/100 000, while the incidence of females was 1.23/100 000. The age with the highest incidence of COVID-19 in Henan Province was 20-69 years old (88.68%). The incidence rate was highest in men aged 30-39 (2.51/ 100 000), while the lowest rate in women aged 0-9 (0.16/100 000). There were 1 225 local patients (96.31%), and the rural patients (45.73%) were slightly higher than the urban patients (44.02%) in Henan Province. A total of 63.60% patients had traveled or lived in Hubei or contacted with people who came from Hubei to Henan. The proportion of patients whose family members suffered from COVID-19 was 32.70%. Global spatial autocorrelation analysis suggested that there was a statistically significant positive correlation in the spatial distribution of COVID-19 patients in Henan Province (Moran's I=0.248, Z=2.955, P<0.01).
Conclusions:
There are differences in the morbidity and mortality of COVID-19 patients in different areas of Henan Province, with epidemic peak reaching from January 24 to January 28. Henan is dominated by local patients, male patients, and patients with contact history in Hubei. The space appears to be moderately clustered.
