The world is suffering from a pandemic called COVID-19, caused by the SARS-CoV-2 virus. The different national governments have problems evaluating the reach of the epidemic, having limited resources and tests to their disposal. Hence, any means to evaluate the number of persons with symptoms compatible with COVID-19 with reasonable level of accuracy is useful.
The objective of this study is the collection and publication of data concerning the number of people that show symptoms compatible with COVID-19 in different countries. This data is useful to estimate the number of infected persons with the COVID-19 virus at a given point in time in these countries, and the evolution of this number over time, using techniques like the Network Scale-up Method.
