MADRID– Spanish health officials say large-scale testing for the new coronavirus has demonstrated there is no herd immunity in the country.
The head of the National Epidemiology Centre, Marina Pollan, says that a major, ongoing survey shows so far that about 5% of the population — around 2 million people — have been infected by the virus.
Officials presented Wednesday preliminary results from the survey, which started in the last week of April and is scheduled to last eight weeks, of 30,000 households which were tested for the virus.
Authorities hope the survey will reveal the true scale of the outbreak, help them monitor its dynamics and steer health policy.
Pollan, said it has revealed deep regional differences, with the worst-hit areas showing a number of infections five times higher than in the least-affected parts of the country.
She said no great difference in infection rates has been detected between age groups or sexes.
Spain has recorded at least 27,000 COVID-19 deaths and almost 229,000 cases.
