MADRID — One in ten residents in Spain had been infected by the coronavirus by mid-November and almost half that contagion occurred during the summer resurgence of outbreaks. That's according to preliminary results of an official survey on the presence of antibodies.
The fourth and latest round of a national seroprevalence study found that 9.9% of the more than 51,400 people tested had developed antibodies at some point since the onset of the pandemic, officials from Spain’s main epidemiological study center, the Carlos III Health Institute, and the Health Ministry said Tuesday.
The study suggests that at least 4.7 million people have contracted the virus so far, although official Health Ministry figures have logged 1.75 million infections from laboratory tests as of Monday.
Spain has also confirmed 48,000 deaths for COVID-19, although excess mortality registries suggest a much higher real death toll.
Marina Pollán, director of the National Epidemiological Center, said that health workers and women taking care of the elderly, working as cleaners and in nursing homes showed the highest prevalence of antibodies.
