Risk assessment of public health emergencies concerned in China, February 2023

Objective: To assess the risk of public health emergencies occurring in China (except Hong Kong, Macao Special Administrative Regions and Taiwan Province, the same below) or possibly imported from outside China in February 2023. Methods: Based on various data and departmental notification information on domestic and foreign public health emergencies reports and surveillance of key infectious diseases, the expert consultation method was used and experts from provincial (autonomous regions and municipalities directly under the central government) centers for disease prevention and control were invited to participate in the assessment by video conference. Results: The number of public health emergencies to be reported in February 2023 is expected to increase compared to former month. In February 2023, affected by immune escape and reinfection of Omicron variants XBB, CH and other possible emerging subtypes, it is expected that the COVID-19 may become endemic in more areas of the world. In China, because of the increased flow of people after the Spring Festival and the opening of schools, the possibility of the spread of the virus will increase. The influenza viruses activity level may increase in February, and influenza A (H1N1) is more likely to be the main influenza virus. Conclusion: Special attention is given to COVID-19, and general attention is given to seasonal influenza.

Risk assessment of public health emergencies concerned in the mainland of China, January 2023

Objective: To assess the risk of public health emergencies occurring in the mainland of China or possibly imported from outside China in January 2023. Methods: Based on various data and departmental notification information on domestic and foreign public health emergencies reports and surveillance of key infectious diseases, the expert consultation method was used and experts from provincial (autonomous regions and municipalities directly under the central government) centers for disease prevention and control were invited to participate in the assessment by video conference. Results: The number of public health emergencies reported in January 2023 is expected to increase or be similar to that reported in December 2022. The COVID-19 rebound in the northern hemisphere is likely to continue in January 2023 due to immune escape of BQ, XBB and other possible emerging Omicron variants' subtypes. The increased migration of people in Chinese mainland during the Spring Festival in 2023 could increase the risk of the spread of the SARS-CoV-2 among uninfected people. The level of influenza virus activity is likely to increase in January, and influenza A is likely to dominate. January 2023 remains risky month for nonoccupational carbon monoxide poisoning. Conclusion: Special attention is given to COVID-19, and general attention is given to seasonal influenza and nonoccupational carbon monoxide poisoning.

Depression and anxiety and assciated factors among college students returned to campus during the outbreak of COVID-19

Objective: The purpose of this study was to investigate the state of depression and anxiety and associated factors of back-to-school college students during the outbreak of COVID-19, so as to provide theoretical basis for emotional counseling and psychological crisis intervention after long-term school closure due to epidemic outbreak.

The Association of Suicidal Ideation With Family Characteristics and Social Support of the First Batch of Students Returning to a College During the COVID-19 Epidemic Period: A Cross Sectional Study in China.

Objective: To investigate the prevalence of suicidal ideation among the first batch of students returning to a college during the COVID-19 epidemic, and to explore the correlation of suicidal ideation with family characteristics and social support. Methods: A cluster sampling survey with a self-designed questionnaire was conducted among the first batch of students returning to a college in Wuhu, China. The Positive and Negative Suicidal ideation (PANSI) and Social Support Scale (SSRS) were used to define students' suicidal ideation and social support, respectively. The influence of family characteristics and social support on the students' suicidal ideation was investigated using multivariate unconditional logistic regression analysis. Results: Two thousand seven hundred valid questionnaires were collected, including 673 males (24.9%) and 2,027 females (75.1%), in this study. A total of 146 students (5.4%) showed suicidal ideation. Male respondents reported higher rates (7.9%) than females (4.6%). Multivariate logistic regression analysis showed that a higher risk level of residence before returning to school and lower objective support were the risk factors for suicidal ideation in males. In contrast, a higher level of maternal education, a poorer relationship with the mother, and lower scores for subjective support and support availability had significant effects on females' suicidal ideation. Limitations: This is a cross-sectional study, and lacks comparison to the time point unaffected by COVID-19. Moreover, it was limited by COVID-19 epidemic prevention and control restrictions, and the differences in returning to school in different regions. Only one college was investigated in this study, and all of the respondents were sophomores, so there may be some limitations in the representativeness of the sample and extrapolation of the results. Conclusion: Family characteristics and social support have had an important influence on suicidal ideation among students returning to school during the COVID-19 epidemic. Some gender differences were identified. Targeted interventions are needed for early prevention and control.
