The World Health Organization’s top official criticized some nations for not doing enough to detect and contain the deadly coronavirus that’s infected more than 174,000 people across the world.
“We have not seen an urgent enough escalation in testing, isolation and contact tracing, which is the backbone of the response,” WHO Director-General Tedros Adhanom Ghebreyesus said.
“We have a simple message for all countries: Test, test, test,” he said.
