The technology I prefer most in the article is the data visualization tools for decision support for COVID-19. Those were widely used during the pandemic period to collect real-time health data, not only representing the confirmed cases but also deaths, hospitalization rates, testing numbers, and even vaccination data. Each country has developed its own dashboard to capture the disease pattern in the region and respond with the appropriate intervention, applying the figures. The WHO Covid-19 dashboard is a good example of a data visualization tool for Covid-19. To establish Data visualization tools, raw data related to Covid 19 has to be collected from all hospitals and healthcare services. Then, it has to be assigned which data are visualized with the type of charts, maps, or patterns in the tool.
Data visualization tools are important for healthcare providers, analysts, and the public. COVID-19 dashboards typically focus on time-lapse charts and geographic maps ranging from region-level statistics to case-level coordinate data. It helps to keep the informed public with the right information and supports policymakers in refining interventions. Public health officers decide on resource allocation, promoting community awareness, preventive measures in the community, etc. in the red zone area. The general public stays informed about the pandemic proximity in the area and it is also updated number of contacts in the district.
