NEW YORK (AP) – A top world health official Monday warned that countries are essentially driving blind in reopening their economies without setting up strong contact tracing to beat back flare-ups of the coronavirus.
The warning came as France and Belgium emerged from lockdowns, the Netherlands sent children back to school, and many U.S. states pressed ahead by lifting business restrictions. In California, Tesla CEO Elon Musk announced the company’s 10,000-worker electric car factory near San Francisco was operating Monday in defiance of coronavirus health orders that closed nonessential businesses.
Authorities have cautioned that the scourge could come back with a vengeance without widespread testing and tracing of infected people’s contacts with others.
Fears of infection spikes in countries that have loosened up came true in recent days in Germany, where new clusters were linked to three slaughterhouses; in Wuhan, the Chinese city where the crisis started; and in South Korea, where a single nightclub customer was linked to 85 new cases.
The World Health Organization’s emergencies chief, Dr. Michael Ryan, said that robust contact tracing measures adopted by Germany and South Korea provide hope that those countries can detect and stop virus clusters before they get out of control.
