As of May 2, 2023, there were roughly 687 million global cases of COVID-19. Around 660 million people had recovered from the disease, while there had been almost 6.87 million deaths. The United States, India, and Brazil have been among the countries hardest hit by the pandemic.

The various types of human coronavirus The SARS-CoV-2 virus is the seventh known coronavirus to infect humans. Its emergence makes it the third in recent years to cause widespread infectious disease following the viruses responsible for SARS and MERS. A continual problem is that viruses naturally mutate as they attempt to survive. Notable new variants of SARS-CoV-2 were first identified in the UK, South Africa, and Brazil. Variants are of particular interest because they are associated with increased transmission.

Vaccination campaigns Common human coronaviruses typically cause mild symptoms such as a cough or a cold, but the novel coronavirus SARS-CoV-2 has led to more severe respiratory illnesses and deaths worldwide. Several COVID-19 vaccines have now been approved and are being used around the world.

This applications maps the spread of coronavirus total cases, deaths, new cases, recovered cases and active cases to identify where COVID-19 infections exist or have occurred.

Background: It is not known how the number of deaths due to COVID-19 compare to the number of deaths due to "unsafe water, sanitation, and handwashing" during the COVID-19 global health emergency. Methods: A dataset of deaths due to COVID-19 was downloaded from the World Health Organization. A dataset summarizing deaths due to unsafe water, sanitation, and handwashing was obtained from the Institute for Health Metrics and Evaluation (IHME).
Results indicate that COVID-19 deaths in Africa and South East Asia regions exceeded those due to unsafe water, sanitation, and hygiene. Methods Two raw datasets were obtained and processed.
To construct the dataset, "Estimates of mortality due to inadequate water, sanitation, and hygiene (WASH) during the COVID-19 Global Health Emergency" raw data were downloaded from the Institute for Health Metrics and Evaluation (IHME). The raw dataset was reduced, eliminating variables. The original IHME dataset was for the year 2019. IMHE does not yet have data for 2020 or beyond. The final data contains calculations that project into 2020-2023 the estimated number of WASH-related deaths, by region. That was done by multiplying the 2019 estimated deaths by regions, by a factor of the duration of the pandemic period/the number of days in 2019, assuming a constant rate. To construct the dataset "Estimates of COVID-19 mortality, by region January 3 2020-May 5, 2023, with assumptions about undercounting" raw data were downloaded from the public WHO Coronavirus (COVID-19) Dashboard. The raw dataset contains COVID-19 mortality data by country, by date. The raw data were tabulated by region (rather than by country) and for the period of January 3, 2020-May 5, 2023 (rather than by date).
