Meanwhile, the Government has announced that it will begin a National Epidemiological Study of SARS-CoV2 infection (this is the virus that causes covid19). The study, agreed yesterday in a meeting of the National Health System's Interterritorial Council, will be carried out by the Spanish Health Department and the Carlos III Health Institute in conjunction with the regional Health Departments. The study is intended to establish the percentage of the population that has developed antibodies to SARS-CoV-2, a factor known as the "seroprevalence".
The information obtained will be of enormous relevance for public health decision-making in Spain as a whole, and will involve more than 36,000 Spanish households randomly selected in collaboration with the National Institute of Statistics (INE) to ensure that the sample will have participants of all age groups and geographical locations. At least 60,000 people will be invited to participate in the study which has been designed in accordance with WHO recommendations for seroprevalence studies against SARS-CoV-2. Those taking part will answer a short questionnaire which will be examined alongside double serological tests to be performed either at home or in health centres to determine if they have antibodies to the virus.
