The high sensitivity of COVID-19 and the need for high accuracy calculations causes the necessity to collect required data sets from reliable sources. Thus all information was collected and categorized from reputable sources such as WHO (World Health Organization) and worldometers site (www.worldometers.info). The worldometers site contains information such as daily mortality statistics, recovery, and newly confirmed cases. Research data including observation data is obtained from a collection of Iranian samples reports in three parts (i.e. death, confirmed and recovered). This countrywide daily information is confirmed by the World Health Organization(WHO). It should be noted that the relevant data was collected between February 19 and May16 2020.
