6,700 foreign workers in Penang screened so far

Big number: Workers at a construction site in Sungai Pinang, Penang. There are 14,436 foreign construction workers in the state.

GEORGE TOWN: Nearly 7,000 foreign construction workers here have been tested for Covid-19 but the question remains on how the screening could help contain the spread of the virus.

Penang Island City Council (MBPP) mayor Datuk Yew Tung Seang said it was difficult to gauge the effectiveness of the screening as most of these foreign workers were staying together with their counterparts working in other sectors.
