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.

Trends of SARS-CoV-2 Infection Among Couriers in Risky Business After the Optimization of Prevention and Control Measures - China, December 2022 to January 2023.

Introduction: On December 7, 2022, China implemented "Ten New Measures" to optimize prevention and control measures for coronavirus disease 2019 (COVID-19). The purpose of this study was to evaluate the national and regional trends of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among couriers in China from December 2022 to January 2023. Methods: Data from the National Sentinel Community-based Surveillance in China was utilized, including participants from 31 provincial-level administrative divisions and Xinjiang Production and Construction Corps. Participants were tested for SARS-CoV-2 infection twice a week from December 16, 2022 to January 12, 2023. Infection was defined as a positive result for SARS-CoV-2 nucleic acid or antigen. The daily average newly positive rate of SARS-CoV-2 infection and the estimated daily percentage change (EDPC) were calculated. Results: In this cohort, 8 rounds of data were collected. The daily average newly positive rate of SARS-CoV-2 infection decreased from 4.99% in Round 1 to 0.41% in Round 8, with an EDPC of -33.0%. Similar trends of the positive rate were also observed in the eastern (EDPC: -27.7%), central (EDPC: -38.0%) and western regions (EDPC: -25.5%). Couriers and community population showed a similar temporal trend, with the peak daily average newly positive rate of couriers being higher than that of community population. After Round 2, the daily average newly positive rate of couriers decreased sharply, becoming lower than that of community population in the same period. Conclusions: The peak of SARS-CoV-2 infection among couriers in China has passed. As couriers are a key population for SARS-CoV-2 infection, they should be monitored continuously.

Trends of SARS-CoV-2 Infection in Rural Area in Sentinel Community-Based Surveillance - China, December 2022 to January 2023.

Introduction: In late 2022, a rapid transmission of Omicron variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) occurred throughout China. The purpose of this study was to provide the latest data and evaluate trends of SARS-CoV-2 infection in rural China among the community population. Methods: Data on SARS-CoV-2 infection among approximately 90,000 participants in rural China were collected by the National Sentinel Community-Based Surveillance (NSCS) system. Participants were tested for SARS-CoV-2 infection (defined as positive for SARS-CoV-2 nucleic acid or antigen) twice weekly from December 16, 2022 to January 12, 2023. The daily average of newly positive rate and its estimated daily percentage change were calculated to describe the national and regional trends of SARS-CoV-2 infection in rural China. Results: In rural China, the daily average new positive rate of SARS-CoV-2 infection peaked at 4.79% between December 20-22, 2022 and then decreased to 0.57% between January 10-12, 2023, with an average decrease of 29.95% per round. The peak of new SARS-CoV-2 infection was slightly earlier and lower in North China (5.28% between December 20-22, 2022) than in South China (5.63% between December 23-26, 2022), and then converged from December 30, 2022 to January 2, 2023. The peak of 6.09% occurred between December 20-22, 2022 in eastern China, while the peak of 5.99% occurred later, between December 27-29, 2022, in central China. Conclusions: Overall, the epidemic wave in rural China peaked between December 20-22, 2022, and passed quickly following the optimization of prevention and control measures. Currently, SARS-CoV-2 infection in community populations in rural China is sporadic.

Understanding the Food Insecurity and Coping Strategies of Indigenous Households during COVID-19 Crisis in Chittagong Hill Tracts, Bangladesh: A Qualitative Study.

This study examined the food insecurity and coping mechanisms among the indigenous Bangladeshi population of the Chittagong Hill Tracts (CHT) region to extract empirical evidence on the ongoing discussion on the COVID-19 pandemic-exacerbated food-insecurity situation. The study adopted a qualitative approach by interviewing 60 indigenous households. Data were collected in two phases between 15 June 2020, and 30 July 2021 in Bangladesh's Chittagong Hill Tracts (CHT) region. Thematic data analyses were performed using the Granheim approach and NVivo-12 software. The authors used Huston's social-ecological theory to explain the indigenous coping mechanisms. The research evidence revealed that most households experienced challenges over daily foods, manifesting in the decreasing consumption of them, the increased price of food items, a food crisis due to an income shock, malnutrition, the shifting to unhealthy food consumption, starvation and hunger, and food insufficiency, thereby leading to mental stress. This study further revealed that the indigenous population took crucial coping strategies to survive the pandemic. In response to COVID-19, they took loans and borrowed foods, reduced expenses, changed their food habits, avoided nutritional foods, relied on vegetables, sold domestic animals and properties, collected forest and hill foods, and depended on governmental and societal relief. This study also provides the in-depth policy actions for the urgent intervention of government, stakeholders, policymakers, NGOs, and development practitioners to take necessary initiatives to enhance the quality of life of the people that were affected by the post-pandemic recovery period.

Risk assessment of public health emergencies concerned in the mainland of China, June 2022

Objective: To assess the risk of public health emergencies, including both indigenous and imported ones, which might occur in the mainland of China in June 2022.

Risk assessment of public health emergencies concerned in the mainland of China, June 2021

Objective: To assess the risk of public health emergencies, both the indigenous ones and the imported ones, which might occur in the mainland of China in June 2021. Methods: An internet based expert counsel was conducted to analyze the surveillance data of public health emergencies and priority communicable diseases in China reported through different channels, and the experts in all provincial centers for disease control and prevention attended this video conference. Results: Generally speaking, it is predicted that the incidence of public health emergencies would be similar in June with May. The risk of imported cases and secondary infections of COVID-19 would continue to exist, but would be controllable. It is the high incidence season of severe fever with thrombocytopenia syndrome and most cases would be sporadic, however, the risk of cluster exits especially in previous epidemic areas. The incidences of food poisoning caused by toxic animal or plant or poisonous mushroom would increase significantly, and the incidences of food poisoning caused by microbe would be high. The earthquake-stricken areas such as Yunnan and Qinghai should further strengthen post-disaster public health responses. The potential flood-stricken areas predicted by the meteorological department need to pay attention to the risks of water-borne, food-borne and vector-borne diseases that may increase after the disaster. Conclusion: Special attention should be paid to COVID-19, and general attention should be paid to severe fever with thrombocytopenia syndrome, food poisoning and natural disaster.

Community Wellbeing Under China-Pakistan Economic Corridor: Role of Social, Economic, Cultural, and Educational Factors in Improving Residents' Quality of Life.

This present article explores the effects of cultural value, economic prosperity, and community mental wellbeing through multi-sectoral infrastructure growth projects under the Belt and Road Initiative. The implications of the social exchange theory are applied to observe the support of the local community for the China-Pakistan Economic Corridor (CPEC). This study explores the CPEC initiative, it's direct social, cultural, economic development, and risk of environmental factors that affect residents' lives and the local community's wellbeing. CPEC is a multibillion-dollar project to uplift economic growth and free trade between Pakistan, China, and other regional stakeholders. Although CPEC is still in its initial phases with partial startups, policymakers and government officials claim this mega project as a "game-changer" in the region, mainly for Pakistan and China. This gigantic project offers the significant potential to generate business slews and employment opportunities with international outreach. Due to the term's newness, numerous studies have recently explored the macro and microeconomic benefits of the CPEC initiatives; still, these projects are theoretical. The existing literature insufficiently explored how helpful CPEC would be to a specific group and how residents perceive its advantages. This study fills in the literature gaps and explores the likely advantageous potential of the CPEC for the regional states. The study applied a convenient sampling technique for the data collection process. It used a mixed-method approach to gain scientific results, with a standardized questionnaire survey of 459 people (300 men and 159 women) from five major cities of Pakistan. The study results designate that residents believe that CPEC infrastructure projects will significantly improve residents' life quality through more job openings and community poverty reduction. Still, they raised their concerns regarding environmental protection issues in the region. The findings specified that residents had an optimistic approach to better educational productivity by adopting environment-oriented policies. Policymakers should establish new CPEC study centers in different areas, and investors should be encouraged to participate in the industrial sector. Officials can overwhelm community worries about environmental degradation. Government officials in both countries can utilize the findings to raise public awareness about CPEC's social, economic, cultural, mental wellbeing, and ecological implications.

COVID-19 induced impact on informal migrants in Bangladesh: a qualitative study

Purpose>This study intends to explore the impact of occupation and income on informal migrants in the face of COVID-19 induced lockdown in Bangladesh and their coping strategies to survive the pandemic situation.Design/methodology/approach>The study adopted a qualitative research design in which four urban areas were chosen purposively from various parts of Dhaka city. The authors conducted 21 semi-structured in-depth interviews, four FGDs and eight months over participant observation for achieving study objectives. The four stages of data analysis used a thematic approach in the interpretive phenomenological analysis.Findings>The results showed that respondents were massively affected due to loss of income and occupation in the period of induced lockdown. Besides, most people lost their earning sources entirely in this amid pandemic which bound them starvation in the mealtime along with several dynamic complications. The findings also revealed that they followed some surviving strategies such as taking loans, reducing expenses, consuming less food, selling land, jewelry, and goods, relatives and neighbor support, and government relief. Although these strategies somewhat supported them to struggle with the situation, their livelihood features became fragile immensely.Research limitations/implications>The findings will be an important guiding principle for the policymakers, aid organizations and development practitioners to prepare development policies for vulnerable informal migrants in developing countries like Bangladesh.Originality/value>This is the first study that explores the informal migrants’ occupation and income during COVID-19 induced lockdown in Bangladesh. This research also highlights coping strategies of the informal migrants to survive the pandemic situation.

Risk Factors for Death Among the First 80 543 Coronavirus Disease 2019 (COVID-19) Cases in China: Relationships Between Age, Underlying Disease, Case Severity, and Region.

BACKGROUND: Knowledge of COVID-19 epidemiology remains incomplete and crucial questions persist. We aimed to examine risk factors for COVID-19 death. METHODS: A total of 80 543 COVID-19 cases reported in China, nationwide, through 8 April 2020 were included. Risk factors for death were investigated by Cox proportional hazards regression and stratified analyses. RESULTS: Overall national case-fatality ratio (CFR) was 5.64%. Risk factors for death were older age (≥80: adjusted hazard ratio, 12.58; 95% confidence interval, 6.78-23.33), presence of underlying disease (1.33; 1.19-1.49), worse case severity (severe: 3.86; 3.15-4.73; critical: 11.34; 9.22-13.95), and near-epicenter region (Hubei: 2.64; 2.11-3.30; Wuhan: 6.35; 5.04-8.00). CFR increased from 0.35% (30-39 years) to 18.21% (≥70 years) without underlying disease. Regardless of age, CFR increased from 2.50% for no underlying disease to 7.72% for 1, 13.99% for 2, and 21.99% for ≥3 underlying diseases. CFR increased with worse case severity from 2.80% (mild) to 12.51% (severe) and 48.60% (critical), regardless of region. Compared with other regions, CFR was much higher in Wuhan regardless of case severity (mild: 3.83% vs 0.14% in Hubei and 0.03% elsewhere; moderate: 4.60% vs 0.21% and 0.06%; severe: 15.92% vs 5.84% and 1.86%; and critical: 58.57% vs 49.80% and 18.39%). CONCLUSIONS: Older patients regardless of underlying disease and patients with underlying disease regardless of age were at elevated risk of death. Higher death rates near the outbreak epicenter and during the surge of cases reflect the deleterious effects of allowing health systems to become overwhelmed.

Sustained Effects of Government Response on the COVID-19 Infection Rate in China: A Multiple Mediation Analysis.

Many scholars have considered the relationship between the government response to COVID-19, an important social intervention strategy, and the COVID-19 infection rate. However, few have examined the sustained impact of an early government response on the COVID-19 infection rate. The current paper fills this gap by investigating a national survey performed in February 2020 and infection data from Chinese cities surveyed 1.5 years after the outbreak of COVID-19. The results suggest that the Chinese government's early response to COVID-19 significantly and sustainedly reduced China's COVID-19 infection rate, and that this impact worked through risk perception, the adoption of protective action recommendations (PARs), and the chain-mediating effects of risk perception and the adoption of PARs, respectively. These findings have important practical value. In demonstrating how government response and infection rate at the macro level are connected to the behaviour of individuals at the micro level, they suggest feasible directions for curbing the spread of diseases such as COVID-19. When facing such public health emergencies, the focus should be on increasing the public's risk perception and adoption of PARs.
