Changing spatiotemporal patterns for hepatitis of unspecified aetiology in China, 2004-2021: a population-based surveillance study. Front Public Health 2023; 11:1177965. [PMID: 37213628 PMCID: PMC10196104 DOI: 10.3389/fpubh.2023.1177965] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2023] [Accepted: 04/14/2023] [Indexed: 05/23/2023] Open
Abstract
Objectives As global efforts continue toward the target of eliminating viral hepatitis by 2030, the emergence of acute hepatitis of unspecified aetiology (HUA) remains a concern. This study assesses the overall trends and changes in spatiotemporal patterns in HUA in China from 2004 to 2021. Methods We extracted the incidence and mortality rates of HUA from the Public Health Data Center, the official website of the National Health Commission of the People's Republic of China, and the National Notifiable Infectious Disease Surveillance System from 2004 to 2021. We used R software, ArcGIS, Moran's statistical analysis, and joinpoint regression to examine the spatiotemporal patterns and annual percentage change in incidence and mortality of the HUA across China. Results From 2004 to 2021, a total of 707,559 cases of HUA have been diagnosed, including 636 deaths. The proportion of HUA in viral hepatitis gradually decreased from 7.55% in 2004 to 0.72% in 2021. The annual incidence of HUA decreased sharply from 6.6957 per 100,000 population in 2004 to 0.6302 per 100,000 population in 2021, with an average annual percentage change (APC) reduction of -13.1% (p < 0.001). The same result was seen in the mortality (APC, -22.14%, from 0.0089/100,000 in 2004 to 0.0002/100,000 in 2021, p < 0.001). All Chinese provinces saw a decline in incidence and mortality. Longitudinal analysis identified the age distribution in the incidence and mortality of HUA did not change and was highest in persons aged 15-59 years, accounting for 70% of all reported cases. During the COVID-19 pandemic, no significant increase was seen in pediatric HUA cases in China. Conclusion China is experiencing an unprecedented decline in HUA, with the lowest incidence and mortality for 18 years. However, it is still important to sensitively monitor the overall trends of HUA and further improve HUA public health policy and practice in China.

Du M, Yuan J, Jing W, Liu M, Liu J. The Effect of International Travel Arrivals on the New HIV Infections in 15–49 Years Aged Group Among 109 Countries or Territories From 2000 to 2018. Front Public Health 2022; 10:833551. [PMID: 35252102 PMCID: PMC8888525 DOI: 10.3389/fpubh.2022.833551] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2021] [Accepted: 01/18/2022] [Indexed: 11/13/2022] Open
Abstract
Objective The prevalent international travel may have an impact on new HIV infections, but related studies were lacking. We aimed to explore the association between international travel arrivals and new HIV infections in 15–49 years aged group from 2000 to 2018, to make tailored implications for HIV prevention. Methods We obtained the data of new HIV infections from the Joint United Nations Programme on HIV/AIDS and international travel arrivals from the World Bank. Correlation analysis was used to explore the relation briefly. Log-linear models were built to analyze the association between international travel arrivals and new HIV infections. Results International travel arrivals were positively correlated with new HIV infections (correlation coefficients: 0.916, p < 0.001). After controlling population density, the median age of the total population (years), socio-demographic index (SDI), travel-related mandatory HIV testing, HIV-related restrictions, and antiretroviral therapy coverage, there were 6.61% (95% CI: 5.73, 7.50; p < 0.001) percentage changes in new HIV infections of 15–49 years aged group associated with a 1 million increase in international travel arrivals. Conclusions Higher international travel arrivals were correlated with new HIV infections in 15–49 years aged group. Therefore, multipronged structural and effective strategies and management should be implemented and strengthened.

Blood-borne chronic viral infections in a large cohort of immigrants in southern Italy: A seven-centre, prospective, screening study. Travel Med Infect Dis 2020; 35:101551. [PMID: 31945499 DOI: 10.1016/j.tmaid.2020.101551] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2019] [Revised: 12/31/2019] [Accepted: 01/02/2020] [Indexed: 12/18/2022]
Abstract
BACKGROUND Aim of this study was to evaluate the prevalence of blood-borne chronic viral infections in immigrants living in southern Italy and identify factors associated to viral infections. METHODS A prospective screening program was performed in seven clinical centers operating in Campania, Apulia and Calabria regions in southern Italy, in order to identify immigrants with HBV, HCV or HIV infections. RESULTS Of 4,125 immigrants observed in the study period, 3,839 (93.0%) agreed to be screened: 381 (9.9%) resulted HBsAg-positive, 136 (3.5%) anti-HCV, 62 (1.6%) anti-HIV and 1,448 (37.7%) HBsAg-negative and anti-HBc-positive. Ongoing or previous HBV infection was observed more frequently in males (p = 0.02 and p < 0.001, respectively), whereas HIV infection in females (p = 0.01). Immigrants from western Africa showed a higher rate of HBsAg positivity (p < 0.0001), HBsAg negativity/anti-HBc positivity (p < 0.0001) and anti-HIV positivity (p = 0.004) compared with those from other geographical areas. At multivariate analysis, ongoing HBV infection was associated with male sex (OR 1.49, 95% CI: 1.04-2.14) and origin from western Africa (OR 4.67, 95% CI: 1.70-12.80) and eastern Europe (OR 3.44, 95% CI: 1.17-10.08). HCV infection showed the tendency to be more frequent among males (OR 1.84, 95% CI: 0.99-3.42). HIV infection was associated with an older age (OR 1.04, 95% CI: 1.01-1.06), origin from western Africa (OR 4.09, 95% CI: 1.26-13.29) and female sex (OR 2.38, 95% CI: 1.29-4,39; p = 0.006). CONCLUSIONS The high prevalence of HBV, HCV and HIV infections in our large cohort of immigrants should definitively prompt Italian Healthcare Authorities to develop adequate cost-effective screening policies.
