There are many COVID-19 vaccines currently available, however, Low- and middle-income countries (LMIC) still have large proportions of their populations unvaccinated. Decision-makers must decide how to effectively allocate available (e.g. boosters or primary series vaccination, which age groups target) but LMIC often lack the resources undergo quantitative analyses vaccine allocation, resulting in ad-hoc policies.

Mathematical models within the Ross–Macdonald framework increasingly play a role in our understanding of vector-borne disease dynamics and as tools for assessing scenarios to respond emerging threats. These threats are typically characterized by high degree heterogeneity, introducing range possible complexities challenges maintain link with empirical evidence. We systematically identified analysed total 77 published papers presenting compartmental West Nile virus (WNV) that use parameter values derived from studies. Using set 15 criteria, we measured dissimilarity compared framework. also retrieved purpose type traced sources their parameters. Our review highlights increasing refinements WNV models. Models prediction included highest number refinements. found uneven distributions evidence values. several parametrizing such complex For parameters common most models, synthesize ranges. The study potential improve quality applicability policy establishing closer collaboration between mathematical modelling work.

In July 2023, the Center of Excellence in Respiratory Pathogens organized a two-day workshop on infectious diseases modelling and lessons learnt from Covid-19 pandemic. This report summarizes rich discussions that occurred during workshop. The participants discussed multisource data integration highlighted benefits combining traditional surveillance with more novel sources like mobility data, social media, wastewater monitoring. Significant advancements were noted development predictive models, examples various countries showcasing use machine learning artificial intelligence detecting monitoring disease trends. role open collaboration between stakeholders was stressed, advocating for continuation such partnerships beyond A major gap identified absence common international framework sharing, which is crucial global pandemic preparedness. Overall, underscored need robust, adaptable frameworks different across sectors, as key elements enhancing future response

The COVID-19 pandemic demonstrated the key role that epidemiology and modelling play in analysing infectious threats supporting decision making real-time. Motivated by unprecedented volume breadth of data generated during pandemic, we review modern opportunities for analysis to address questions emerge a major epidemic. Following broad chronology insights required - from understanding initial dynamics retrospective evaluation interventions, describe theoretical foundations each approach underlying intuition. Through series case studies, illustrate real life applications, discuss implications future work.

Epidemiological delays are key quantities that inform public health policy and clinical practice. They used as inputs for mathematical statistical models, which in turn can guide control strategies. In recent work, we found censoring, right truncation, dynamical bias were rarely addressed correctly when estimating these biases large enough to have knock-on impacts across a number of use cases. Here, formulate checklist best practices reporting epidemiological delays. We also provide flowchart practitioners based on their data. Our examples focused the incubation period serial interval due importance outbreak response modeling, but our recommendations applicable other The recommendations, literature experience delay distributions during responses, help improve robustness utility reported estimates guidance evaluation downstream transmission models or analyses.

The COVID-19 pandemic led to an unprecedented demand for projections of disease burden and healthcare utilization under scenarios ranging from unmitigated spread strict social distancing policies. In response, members the Johns Hopkins Infectious Disease Dynamics Group developed flepiMoP (formerly called COVID Scenario Modeling Pipeline), a comprehensive open-source software pipeline designed creating simulating compartmental models infectious transmission inferring parameters through these models. framework has been used extensively produce short-term forecasts longer-term scenario at state county level in US, other countries various geographic scales, more recently seasonal influenza. this paper, we highlight how evolved throughout address changing epidemiological dynamics, new interventions, shifts policy-relevant model outputs. As reached mature state, provide detailed overview flepiMoP's key features remaining limitations, thereby distributing its documentation as flexible powerful tool researchers public health professionals rapidly build deploy large-scale complex any pathogen demographic setup.

Over the past several years, emergence of novel SARS-CoV-2 variants has led to multiple waves increased COVID-19 incidence. When Omicron variant emerged, there was considerable concern about its potential impact in winter 2021-2022 due fitness. However, also uncertainty regarding likely questions relative transmissibility, severity, and degree immune escape. We sought evaluate ability an agent-based model forecast incidence context this emerging pathogen variant. To project cases deaths Indiana, we calibrated our hospitalizations, deaths, test-positivity rates through November 2021, then projected April 2022 under four different scenarios that covered plausible ranges Omicron's Our initial projections from December 2021 March indicated a pessimistic scenario with high disease peak weekly Indiana would be larger than previous 2020. retrospective analyses indicate severity closer optimistic scenario, even though hospitalizations reached new peak, fewer occurred during peak. According results, rapid spread consistent combination higher transmissibility escape earlier variants. updated starting January accurately predicted mid-January decline rapidly over next months. The performance shows following variant, models can help quantify range outbreak magnitudes trajectories. Agent-based are particularly useful these because they efficiently track individual vaccination infection histories varying degrees cross-protection.
