2. Given COVID-19's unknowns, vigilance is key: WHO briefing

Early results from seroepidemiology data have begun to show the extent of the infection in people who may have been missed by surveillance measures, Dr Maria Van Kerkhove, a World Health Organization (WHO) Technical Lead, said at a briefing in Geneva Monday. This tool is helping experts detect antibody levels in those individuals, she said.

The results currently available suggest that there are many more people the disease can infect, said Van Kerkhove, making it all the more important that communities remain vigilant when it comes to identifying cases and stamping them out.

“It's important that we understand at this point in time, four months into a global pandemic, a large proportion of the population still remains susceptible", said Van Kerkhove.
