2 Mideast countries, world's top virus rates per population

The small, neighboring sheikhdoms of Bahrain and Qatar have the world's highest per capita rates of coronavirus infections. In the two Mideast countries, COVID-19 epidemics initially swept undetected through camps housing healthy and young foreign laborers, studies now show. In Qatar, a new study found that nearly 60% of those testing positive showed no symptoms at all, calling into question the usefulness of mass temperature checks meant to stop the infected from mingling with others.
