I informed the Ministry of Health of Iran about these reports of COVID-19 epidemic models for Iran. They listened and went on their deficient way.
Not to forget:
(1) China reacted with the lowest speed, releasing the virus to the world. WHO reacted reluctantly. The world nagged and then let it go.
(2) The course of events showed that the function of the Ministers of Health and Public Health Officers (and their equivalent positions, e.g., Health Deputy Ministers) indicated that their decisions are primarily driven by POLITICS rather than PUBLIC HEALTH. This is particularly true about Iran and Canada. Iran deliberately chose free propagation of virus for a delusional objective of herd immunity.
(3) Epidemic models for COVD-19 are generally weak (i.e., of low predictive validity), and the emergence of newer variants practically makes them flail until the new wave has started to rise. I have looked at this, and the manuscript will be ready in future, with codes and details to be placed here: https://github.com/pourmalek/CovidLongitudinal
(4) The available vaccines do not substantially reduce the spread of the virus. This puts evolutionary pressure on the virus for the emergence of newer immune-evasive variants that are more spreadable and / or fatal. The problem will remain without vaccines that stop transmission and without effective suppression of airborne propagation. These are necessary components of the solution but not a sufficient collection of components.
(6) Governments have chosen to set the current and ongoing (low or high) levels of morbidity and mortality of the people to preserve the economy and stability. People have regressed into personal and family survival mode. Numerable individuals speak, and no one listens. Environmental degradation (consequences of which includes the infamous global warming) is an existential threat for Homo sapiens, and the causes and solutions have been explained since the 1970s.
Among the Eastern Mediterranean countries, only Tunisia had more COVID-19 deaths than Iran in July 2002.

CovidVisualized: Visualized compilation of international updated models’ estimates of COVID-19 pandemic at global and country levels
Farshad Pourmalek, MD PhD
SUMMARY
Objectives: To identify international and periodically updated models of the COVID-19 pandemic, compile and visualize their estimation results at the global and country levels, and periodically update the compilations. When one or more models predict an increase in daily cases or infections and deaths in the next one to three months, technical advisors to the national and subnational decision-makers can consider this early alarm for assessment and suggestion of augmentation of preventive measures and interventions.
Methods and Results: Five international and periodically updated models of the COVID-19 pandemic were identified, created by: (1) Massachusetts Institute of Technology, Cambridge, (2) Institute for Health Metrics and Evaluation, Seattle, (3) Imperial College, London, (4) Los Alamos National Laboratories, Los Alamos, and (5) University of Southern California, Los Angeles. Estimates of these five identified models were gathered, combined, and graphed at global and two country levels. Canada and Iran were chosen as countries with and without subnational estimates, respectively. Compilations of results are periodically updated. Three Github repositories were created that contain the codes and results, i.e., “CovidVisualizedGlobal” for the global and regional levels, “CovidVisualizedCountry” for a country with subnational estimates – Canada, and “covir2” for a country without subnational estimates – Iran.
Keywords: COVID-19, pandemic, epidemic, models, visualization, global, Canada, Iran
BACKGROUND
Objectives and rationale:
The objectives are to identify international and periodically updated models of the COVID-19 epidemic, compile and visualize their estimations’ results at the global and country levels, and periodically update the compilations. The ultimate objective is to provide an early warning system for technical advisors to the decision-makers. When the predictions of one or more models show an increase in daily cases or infections, hospitalizations, or deaths in the next one to three months, technical advisors to the national and subnational decision-makers may consider assessing the situation and suggesting augmentation of non-pharmacologic preventive interventions and vaccinations. No similar work provides visualization of the models’ results in one place and keeps records of the previous updates. This paper describes why and how the CovidVisualized tools were created and how countries can use them. It is possible to create and use such an early warning tool for future surges in the pandemic in a way that is usable by researchers and the technical advisers to policymakers.
METHODS
Eligibility criteria: The criteria for inclusion of target COVID-19 models were (1) an international model scope and (2) periodic updates. “International model” denotes a model that estimates COVID-19 cases or infections and deaths for all countries of the world, with global-level estimates that equate the sum of the national-level estimates. “Periodically updated” denotes a model with a record of periodically updated estimates since its first release, with continued updates in 2021.
Finding the eligible models: The eligible models were found within the literature search of a previous publication, “Rapid review of COVID-19 epidemic estimation studies for Iran” [1]. The results were verified by comparison with models found in a study on “Predictive performance of international COVID-19 mortality forecasting models” [2].
RESULTS
Results are described under the following items: (1) Identified eligible models, (2) The CovidVisualized repositories created in this work, (3) Data management, and (4) Periodical uptakes.
(1) Identified eligible models
Five international and periodically updated models of the COVID-19 pandemic were identified: (1) DELPHI , Massachusetts Institute of Technology, Cambridge (abbreviation used in this work: DELP) [3], (2) Institute for Health Metrics and Evaluation, Seattle (IHME) [4], (3) Imperial College, London (IMPE) [5], (4) Los Alamos National Laboratories, Los Alamos (LANL) [6], (5) University of Southern California, Los Angeles, by Srivastava, Ajitesh (SRIV) [7].

The COVID-19 pandemic model by Youyang Gu [https://covid19-projections.com and https://github.com/youyanggu/covid19_projections] and the model by University of California, Los Angeles model [https://covid19.uclaml.org/info.html and https://github.com/uclaml/ucla-covid19-forecasts/tree/master/current_projection] could not be categorized as international and periodically updated models. The COVID-19 International Modelling Consortium (CoMo Consortium) model, created by researchers at the University of Oxford and Cornell University [https://www.medsci.ox.ac.uk/news/como-consortium-the-covid-19-pandemic-modelling-in-context and https://github.com/ocelhay/como], and CovidSim (COVID Simulation) model, developed by researchers at Imperial College, London [https://covidsim.org/v5.20210727/?place=ca and https://covidsim.org/v5.20210727/?place=ir], provide templates for researchers to model the future of epidemic trajectory at national and subnational levels of their choice, through adjusting the model inputs and setting the time horizon into future for the estimations. Unlike the five international and periodically updated models mentioned above, the latter two models are not intended for periodic updates by their original creators. The CoMo Consortium has engaged some countries, including Iran, but not Canada. There is no evidence of either model being used on a periodically updated basis in Iran or Canada.
(2) The CovidVisualized repositories created in this work
Repositories for codes and data sharing: Three Github repositories were created for this project: “CovidVisualizedGlobal” [8] for the global and regional levels, “CovidVisualizedCountry” [9] for countries with subnational estimates, and “covir2” [10] for countries without subnational estimates. Canada and Iran were chosen for case representation of each of the two types of countries, respectively. These are referred to as CovidVisualized GitHub repositories hereon . Six World Health Organization regions were used for the regional level: African Region (AFR), Americas Region (AMR), Eastern Mediterranean Region (EMR), European Region (EUR), South-East Asian Region (SEAR), and Western Pacific Region (WPR).
Four of the five identified models share codes and estimates updates via GitHub repositories, and the IHME estimates are released on IHME’s website [4].
GitHub repositories allow others to view and/or download, scrutinize, and verify the integrity of the codes and data. It is also possible to minimally modify the codes to recreate similar repositories for any other country that reports COVID-19 cases and deaths to World Health Organization. Such use of the codes and data in GitHub is free of charge and bound to the pertinent licenses.

(3) Data management
Data management: A template was created to assign comparable variable names to various outcomes from different models. The CovidVisualized methodology document explains the conceptual and computational details of the development of CovidVisualized tools and provides example [11]. Stata SE 14.2 (Stata Statistical Software. StataCorp. College Station, Texas) was used to write and run the codes. Graphs for all types of predicted outcomes, their mean estimates and uncertainty limits, and different scenarios within each model where available are created. IHME and IMPE models have alternative (e.g., “better” and “worse) scenarios besides their reference (aka status quo) scenario. Predictions’ graphs are shown on the pages of the three CovidVisualized GitHub repositories [8-10] and in periodical Situation Reports created with each uptake. The DELP and IHME models provide subnational-level estimates for countries reporting national and subnational level COVID-19 outcomes. Graphs were created for national and subnational-level locations (i.e., provinces in Canada) available in DELP and IHME model outputs.
(4) Periodical uptakes
Periodical uptakes: The two models with the least frequency of periodic updates of estimates are IHME and IMPE, updated almost weekly and bi-weekly, respectively – until November 2021. After the spread of the Omicron variants, these models reduced the frequency of their update releases. Therefore, two sets of arrangements ruled the frequency of performing uptakes in the CovidVisualized tools. The first set covered the year 2021: With the release of each update of either of these two models, the whole set of the five included models are updated in all the three CovidVisualized GitHub repositories. The most recent update of each model is used. The conventions for periodical uptake are described in detail in CovidVisualized methodology document [11]. R software via RStudio 1.4 (Integrated Development for R. RStudio. PBC, Boston, Massachusetts) was used for semi-automatization of the uptakes’ execution. Estimates of the LANL model get updated about every 3-4 days, and DELP and SRIV models get updated daily. The second set of arrangements for the frequency of performing uptakes in the CovidVisualized tools started in 2022. Uptakes are conducted each week on Friday. Each uptake uses the latest available update of each model.
Similar work: The “covidcompare” tool [12] provides graph visualization of the latest estimates of daily and total deaths from international and periodically updated COVID-19 models for countries of the world and US states, along with historical forecasts and model performance, based on IHME’s “Predictive performance of international COVID-19 mortality forecasting models” [2].
LIMITATIONS, STRENGTHS, AND FURTHER DIRECTIONS
Limitations: Limitations of this work include the programming languages, automatization of uptakes, and choice of the website for presentation of the results.
Stata programming language constitutes about 99% of the codes. Whereas Stata is a commercial software package, using non-commercial packages such as R and/or Python can increase the accessibility and adaptability of the codes for other researchers. Further use of R and/or Python can also make the uptakes almost fully automatized. Some health researchers may not be familiar with GitHub and GIT programming. Therefore, additional use of a dedicated website that is more visible to and accessible for the target audience can increase the reach and effect of this work.
Strengths and weaknesses of individual international and periodically updated COVID-19 pandemic models are not mentioned here, but they have been discussed elsewhere [1-2,11].
Strengths: Strengths of this work include usability for informing technical advisors to the decision-makers, adaptability for use in other countries, and automatized data acquisition.
Tested usability for informing technical advisors to the decision-makers at the country level: Results of the GitHub repository “covir2” [15] were used to present the predictions of the five international and periodically updated models of COVID-19 pandemic about the possibility, timing, slope, height, and drivers of a potential fifth wave of the epidemic in Iran. This presentation was done using the results of the covir2 repository along with the results of an e-mail survey of more than 40 epidemiologists and public health specialists. The predictions and results were presented and described in a live online session for four Deputy Ministers of Health and six epidemiologists selected by Iran’s Ministry of Health and Medical Education (MOHME). Periodical situation reports based on each uptake are also shared with MOHME.
Adaptability of the codes for use in other countries or regions in the world: The codes available in GitHub repositories “CovidVisualizedCountry” [9] and “covir2” [10] can be slightly modified by any researcher to be used for countries with and without subnational estimates respectively. See examples for Afghanistan, Pakistan, Japan 20210506, Japan 20210928. “CovidVisualizedCountry” can be adjusted for use for any type of regionalization of the countries / locations of the world, e.g., World Health Organization regions.
Automatized data acquisition: The Stata codes in these repositories automatically download the estimates’ data files from the five included models once executed. There is no additional need for users to locate, download, and edit the estimates’ data of individual models before running the codes. This automatic data acquisition further enhances computational reproducibility – “obtaining consistent results using the same input data; computational steps, methods, and code; and conditions of analysis” [https://doi.org/10.17226/25303].
Further research: Further directions include using the “ensemble” method to statistically combine models’ estimates, and retrospective assessment of models’ predictive performance. In ensemble methods, individual models are evaluated for minimum requirements of quality and reporting. They are statistically combined using specific relative weights for each model, where the weights reflect the comparative accuracy of each model. Such ensemble methods are used by European Centre for Disease Prevention and Control [https://covid19forecasthub.eu/background.html and https://github.com/epiforecasts/covid19-forecast-hub-europe] and US COVID-19 Forecast Hub [https://covid19forecasthub.org/doc/ensemble and https://github.com/reichlab/covid19-forecast-hub]. The ensemble models have been empirically shown to be more accurate than any of the individual models used in the ensemble method [https://www.medrxiv.org/content/10.1101/2021.02.03.21250974v3]. Retrospective assessment of models’ predictive performance includes using statistical and graphical methods to estimate and visualize the accuracy of models’ estimations [2].
