The dire state of the COVID-19 pandemic crisis symbolized the urgency for efficient distribution and administration of vaccines to combat the virus as the most urgent public health service. This paper presents a prototype multi-criteria decision support model based on goal programming that can effectively support vaccination plans for the greater good of society. The optimization goals of the model include minimizing the number of fatalities and risk of spreading the disease, while complying with government health agency’s priority guidelines for vaccination. This study applied the model to a real-world dataset to demonstrate how it can be effectively applied as …

This study examines the impact of coronavirus disease 2019 (COVID-19) test accuracy (i.e., sensitivity and specificity) on the progression of the pandemic under two scenarios of limited and unlimited test capacity. We extend the classic susceptible–exposed–infectious–recovered model to incorporate test accuracy and compare the progression of the pandemic under various sensitivities and specificities. We find that high-sensitivity tests effectively reduce the total number of infections only with sufficient testing capacity. Nevertheless, with limited test capacity and a relatively high cross-infection rate, the total number of infected cases may increase when sensitivity is above a certain threshold. Despite the potential for …

Headquarters Report: A Look Back, A Step Forward, Karen Burgess Cae
The Journal of the Michigan Dental Association
In her Headquarters Report, MDA Executive Director Karen Burgess reflects on the dental landscape entering the third year of the COVID-19 pandemic, acknowledging the "new normal" with increased demand for services, staff shortages, and supply chain challenges. Despite uncertainties, the Michigan Dental Association (MDA) maintained membership numbers better than expected, with a slight decrease in market share. The report emphasizes the importance of member value, highlighted by a favorable Net Promoter Score (NPS) and positive feedback on MDA benefits. It also discusses efforts in diversity, equity, and inclusion, along with successful advocacy initiatives influencing oral health in Michigan.

The novel coronavirus disease 2019 (COVID-19) has caused a global pandemic. Some studies have suggested a negative association between sunlight intensity and COVID-19 infection, alluding to the belief that it might be safe to go out on sunny days. This paper examined whether solar radiation mitigated the association between human mobility and COVID-19 infection in Europe using a dynamic panel data model to investigate the effect of human mobility, solar radiation, and their interaction on COVID-19 infection. The results revealed that outgoing mobility was positively correlated and solar radiation was negatively correlated with COVID-19 infection at lag levels of 1, …
