WHO: Not all countries followed WHO advice on COVID-19

World Health Organization (WHO) on Tuesday tweeted that since January 30, the organization has been urging countries to prepare to find, test, treat and isolate every COVID-19 patient and trace all contacts. Some, but not all, countries have followed the international health body's advice.

WHO Director-General Tedros Adhanom Ghebreyesus on Tuesday said the "WHO has no power or force to reinforce its advice, except the willingness of the countries to accept or reject. ... WHO will continue to give advice based on science and evidence and then it will be up to countries whether to take it or not."

As of Tuesday, the number of global confirmed COVID-19 cases exceeded three million, with the death toll surpassing 210,000. The U.S. has recorded the most COVID-19 cases at nearly one million, according to the latest statistics released by Johns Hopkins University.
