Beirut, July 12 (RHC)-- Lebanon has recorded more than 100 new infections in the last day, its highest daily increase yet, with most of the cases among workers of a cleaning company, the health minister said.

"To reassure people, the source is known," health minister Hamad Hassan told broadcaster LBC.  He added that up to 75 percent of the cases were linked to what he described as a big cleaning company, were symptom-free and non-Lebanese.

Hassan said 800 workers from the cleaning company in question needed to be tested, along with another 1,000 workers from two other companies with whom they were connected.  "The number will remain high this week," he said.
