COVID-19 pandemic in Spain
The ongoing COVID-19 pandemic was first confirmed to have spread to Spain on 31 January 2020, when a German tourist tested positive for SARS-CoV-2 in La Gomera, Canary Islands. [Post-hoc genetic analysis has shown that at least 15 strains of the virus had been imported, and community transmission began by mid-February. By 13 March, cases had been confirmed in all 50 provinces of the country.
A state of alarm and national lockdown was imposed on 14 March. On 29 March it was announced that, beginning the following day, all non-essential workers were ordered to remain at home for the next 14 days. By late March, the Community of Madrid has recorded the most cases and deaths in the country. Medical professionals and those who live in retirement homes have experienced especially high infection rates. On 25 March the death toll in Spain surpassed that of mainland China, and only Italy's was higher. On 2 April, 950 people died of the virus in a 24-hour period—at the time, the most by any country in a single day.
As of 20 May 2020, there have been 232,555 confirmed cases and 27,888 deaths while there have been 150,376 recoveries. The actual number of cases was considered to be much higher, as many people with only mild or no symptoms were unlikely to have been tested. On 13 May, the results of the first wave of a Spanish Government nation-wide seroprevalence study showed that the percentage of population which could have been infected during the pandemic would be around 5%, approximately 2 million people, a figure ten times higher than the number of confirmed cases on that date. According to this study based on sample of more than 63,000 people, Madrid and Castilla–La Mancha would be the most affected regions with a percentage of infection greater than 10%. The number of deaths is also believed to be an underestimate due to lack of testing and reporting, perhaps by as much as 5,700–6,000 according to different excess mortality analysis. However, 17 May was the first time when the daily death toll announced by the Spanish government fell below 100 after two months.
