Lebanon has reported 166 new cases in the last 24 hours - its highest record in a single day since February.
More than 133 of the newly registered infections are among Syrians working for Ramco, a waste management company that collects rubbish in Lebanon and employs Bengali and Syrian workers.
The company's car park has been turned into a quarantine area for those who have been infected, while hundreds of other workers will be tested.
Foreign workers are poorly paid in Lebanon with no legal rights to protect them, but in this case the employees' treatment and accommodation is being provided by Ramco and the Lebanese ministry of health.
With restrictions easing and the country opening up, many people are not adhering to protective measures such as social distancing and wearing masks in public spaces, and it is feared that Lebanon could face a second wave of infections.
