COVID-19 virus SARS-CoV-2

Epidemiological Profile of Spain

The evolution of COVID-19 epidemiology in Spain between March 1, 2020 and September 12, 2021. Data is expressed as the weekly number of reported positive cases per 100000 of the Spanish population. Spanish population (46,7 million) has reached its 60% herd immunity threshold just after February 2, 2021, however, it is now becoming clear that natural exposure to this mild disease must substantially exceed this threshold in order for the natural herd immunity to become effective. Also, notice the entrance into profound incidence fluctuations despite maintanance of very strict social distancing measures by the Spanish government.

Here, raw data of weekly reported cases is plotted together with the profile of Spanish infection fatality ratio (IFR). Despite very strict social distancing measures implemented by the Spanish authorities the COVID-19 epidemic in that country shows no sign of respite confirming the futility of the use of lock downs, and other severe restrictions to curb COVID-19 disease. In addition, in Spain the use of severe social distancing measures did not prevent excessive fatalities.

The mortality (IFR) at the beginning of 2021 associated with COVID-19 in Spain was excessive.
