Machine learning algorithms (ML) are receiving a lot of attention in the development of predictive models for monitoring dengue transmission rates. Previous work has focused only on specific weather variables and algorithms, and there is still a need for a model that uses more variables and algorithms that have higher performance. In this study, we use vector indices and meteorological data as predictors to develop the ML models.

Community Insights in Phylogenetic HIV Research: The CIPHR Project Protocol.

Glob Public Health

January 2023

Institute for Global Public Health, Department of Community Health Sciences, University of Manitoba, Winnipeg, Canada.

Inferring HIV transmission networks from HIV sequences is gaining popularity in the field of HIV molecular epidemiology. However, HIV sequences are often analyzed at distance from those affected by HIV epidemics, namely without the involvement of communities most affected by HIV. These remote analyses often mean that knowledge is generated in absence of lived experiences and socio-economic realities that could inform the ethical application of network-derived information in 'real world' programmes.

Rotavirus molecular surveillance remains important in the postvaccine era to monitor the changes in transmission patterns, identify vaccine-induced antigenic changes and discover potentially pathogenic vaccine-related strains. The Canadian province of Alberta introduced rotavirus vaccination into its provincial vaccination schedule in June 2015. To evaluate the impact of this program on stool rotavirus positivity rate, strain diversity, and seasonal trends, we analyzed a prospective cohort of children with acute gastroenteritis recruited between December 2014 and August 2018.

Background: Yellow fever has become a re-emerging disease of public health importance, especially in endemic areas like Nigeria and South America. Since 2017, Nigeria has been riddled with yearly outbreaks of the disease despite the availability of a safe and effective vaccine which was introduced into the country's Expanded Programme on Immunization in 2004. We aim to describe the presentation pattern of patients with the disease who were managed in the 2020 outbreak that occurred in Delta State.

Article Synopsis
  • Trends in severe COVID-19 outcomes in Canada highlight a shift in hospitalization rates and associated risks during different waves of the pandemic, particularly higher admissions in the later waves.
  • A study conducted across 155 hospitals included both adults and children, examining data from March 2020 to May 2022, focusing on severe outcomes such as ICU admissions and death rates.
  • Findings indicate that while overall hospitalizations increased in later waves, the rates of severe outcomes were lower, especially among vaccinated patients compared to the unvaccinated.

We identified key risk factors for HIV among people who inject drugs (PWID) in Pakistan and explored access to free clean needles. Multivariable logistic regression was used to investigate associations between HIV prevalence and demographic, behavioral, and socio-economic characteristics of PWID. Data came from the Government of Pakistan's Integrated Biological and Behavioral Surveillance (IBBS) Round 5 (2016-17; 14 cities).

Background: Recording real-time data of vaccinations performed, vaccine stocks, and adverse events following immunization is a particularly useful activity in the effective development of any vaccination campaign or vaccination program, guiding the decisions of public health authorities. The aim of this paper is to present the benefits of the National Electronic Registry of Vaccinations in providing useful information for the optimization of healthcare vaccination policies, specifically related to COVID-19 vaccination.

Methods: We performed a descriptive study using data available in the reports generated from the National Electronic Registry of Vaccinations regarding COVID-19 vaccinations performed between 27 December 2020 and 31 December 2021.

The accurate measurement of serological response to SARS-CoV-2 vaccination is needed to correlate responses with effective protective immunity. The World Health Organization (WHO) has created an international standard to allow harmonization of immune response assessment to an arbitrary unit across different commercial assays; however, the accuracy of reporting of SARS-CoV-2 spike antibody titers in international standard units (BAU or IU/mL) from commercial assays is not well studied. Here, we report the performance comparison of four quantitative commercial assays testing for SARS-CoV-2 spike immunoglobins using the WHO's international standard.
