Objective: This study explored vaccine exemption clustering in Michigan and examined whether vaccine exemptions clustered by exemption type (medical, religious, and philosophical). Furthermore, the study investigated whether Michigan's nonmedical vaccine exemption policy change had an impact on type-specific vaccine exemption clusters following its implementation.
Methods: The study used the ArcGIS optimized hot spot analysis tool to visually examine vaccine exemption clustering by type in Michigan. The study analyzed secondary kindergarten vaccine exemption data from 2301 elementary school buildings in Michigan for years spanning 2008 to 2015 and 2016 to 2017 post policy change.
Results: Clustering of vaccine exemptions by type was present both before and after implementation of the policy with fewer statistically significant features and differences regarding the distribution of hot spot clusters following the policy change.
Conclusion: Considering the heterogeneity in vaccine exemption hot spot clustering by type can help to inform public health officials to areas/communities at high risk for vaccine preventable disease outbreaks. Such analysis can allow for the implementation of vaccine exemption interventions that are exemption type specific and tailored for a given area, thus maximizing impact and making best use of limited public health resources. This analysis was also able to showcase the impact of Michigan's nonmedical vaccine exemption policy on vaccine exemption hot spot clusters.

Mistrust and barriers to influenza vaccination are well-documented in the literature. Underserved populations, including the Hispanic community, experience social determinants of health that exacerbate their health outcomes, including for common preventable illnesses such as influenza (flu). There is currently a gap in the literature regarding the knowledge, barriers to access, and trust of the Hispanic community regarding the influenza vaccine.

Background: To analyse the epidemiological characteristics and variation trend of influenza in Zhejiang Province from 2018 to 2023, so as to provide reference for the prevention and control of influenza after COVID-19 pandemic.
Methods: Throat swab samples of influenza-like illness (ILI) cases from 16 local sentinel hospitals were collected every week, and real-time reverse transcription-polymerase chain reaction (RT-PCR) was used to detect and identify the specific types of influenza viruses. Descriptive epidemiological method was used to analyse the surveillance data from sentinel hospitals and network laboratories.

Background: Occupational COVID-19 remains a challenge among healthcare personnel (HCP).
Methods: This study documents three COVID-19 outbreaks that occurred among vaccinated HCP within a single health care system (HCS) in California, USA in June and August 2023. The Employee Health (EH) unit for the HCS conducted surveillance with structured interviews, identifying outbreaks in real-time.

A total of 2079 healthcare workers (HCWs) responded to an anonymous survey on vaccine hesitancy conducted between December 2022 and October 2023 at centers in Lithuania, Portugal, Poland, Germany, and Brazil. Only 55.7% were confident about the long-term safety of the COVID-19 vaccine; 10% believed the risk of having COVID-19 vaccines was greater than the risk of COVID-19 itself.

Background: Unsafe sex remains a critical threat to the life and health of females. Following the latest Global Burden of Disease (GBD) 2021 estimates, this study updated the global spatiotemporal trends of disease burden attributable to unsafe sex in females, and firstly conducted forecasts to 2035, to guide the resource allocation and the development of public health strategies.
Methods: The number and age-standardized rates (ASRs) of unsafe-sex-related deaths and disability-adjusted life years (DALYs) in females from 1990 to 2021 were retrieved from GBD 2021.
