Epidemiology of influenza virus reinfection in Guangxi, China: a retrospective analysis of a nine-year influenza surveillance data: Characteristics of influenza virus reinfection.

Background: Epidemiological characteristic profile of the reinfection of the influenza virus has not been well described.

Methods: This study included all influenza cases of Guangxi, China from January 2011-December 2019 that were recorded in the National Notifiable Infectious Disease Reporting Information System (NIDRIS) within 24 hours after diagnosis.

Results: A total of 53,605.

Genetic Characterization of Two Human Cases Infected with the Avian Influenza A (H5N6) Viruses - Guangxi Zhuang Autonomous Region, China, 2021.

What Is Known About This Topic?: H5N6 has replaced H5N1 as a dominant avian influenza virus (AIV) subtype in southern China. The increasing genetic diversity and geographical distribution of H5N6 pose a serious threat to the poultry industry and human health.

What Is Added By This Report?: A total of 2 cases of H5N6 that occurred from February 2021 to July 2021 in Guangxi, China were reported in this study.

A Population-Based Acute Meningitis and Encephalitis Syndromes Surveillance in Guangxi, China, May 2007-June 2012.

Objectives: Acute meningitis and encephalitis (AME) are common diseases with the main pathogens being viruses and bacteria. As specific treatments are different, it is important to develop clinical prediction rules to distinguish aseptic from bacterial or fungal infection. In this study we evaluated the incidence rates, seasonal variety and the main etiologic agents of AME, and identified factors that could be used to predict the etiologic agents.

[Investigation of a family clustering of human infection with avian influenza A (H7N9) virus in Nanning, Guangxi].

Objective: To understand the transmission mode of human infection with avian influenza A (H7N9) virus.

Methods: Field epidemiological investigation was conducted for a family clustering of human infection with H7N9 virus in Hengxian county, Guangxi Zhuang Autonomous Region in February 2014. Two patients and their 82 close contacts were surveyed.

[Surveillance and research on acute meningitis, encephalitis syndrome in Guangxi, China].

Objective: To estimate disease burden and epidemiological characteristics of acute meningitis/encephalitis, and provide the basis for the disease control strategy development.

Methods: A syndrome surveillance system was established in Guigang city with a population of 5 020 000. For the suspected cases, serum and CSF were collected, and bacterial culture, latex agglutination test, real-time PCR and ELISA tests were carried out.

[Identification and analysis of an SEO strain of hemorrhagic fever with renal syndrome hantavirus from Guangxi].

Objective: To identify hantavirus from lung specimens of rats captured in Guangxi.

Methods: Rats were collected from various areas in Guangxi in combination with plague surveillance and rat lung specimens were examined by ELISA for hantavirus antigen, and M segment of positive specimen was partially amplified with RT-PCR and sequenced. Phylogenetic analysis was conducted for genotyping.
