ATHENS — Greece’s Health Ministry says it will carry out coronavirus antibody tests on public health and support workers across Greece this month as part of its efforts to monitor the course of the nation's outbreak.

The Health Ministry said Tuesday that the testing will be carried out on a voluntary basis.. The plan was announced as Greece prepares to reopen to foreign tourists starting June 15.

Early and strictly enforced lockdown measures helped keep Greece's infection rates comparatively low, and officials hope that will help entice summer visitors.

The government is racing to reopen international access to its resorts and to augment health care resources on the Greek islands and in mainland cities popular with vacationers.
