Qatar "red risk level" in Harvard COVID-19 map
The announcement came after the COVID-19 risk level map developed by teams at Harvard’s Global Health Institute and Edmond J. Safra Center for Ethics put Qatar as one of the three countries globally to be at the "red risk level."
Countries that report more than 25 cases for every 100,000 people a day are at the red risk level, the most severe stage of the outbreak. There are three countries in the red level category: Qatar, Bahrain, and French Guiana.
A complete lockdown is necessary at this stage to prevent the virus from spreading further, according to the experts.
Coronavirus cases have also jumped in the UAE and Saudi Arabia, following the lifting of some lockdown measures in both countries.
Oman and Kuwait were both ranked orange, while Bahrain joined Qatar as one of the three red risk countries.
