HONG KONG – The Hong Kong government is studying the feasibility of introducing antibody tests for arrivals from overseas to reduce the risks of imported cases, Chief Executive Carrie Lam Cheng Yuet-ngor said on Tuesday.

Speaking to reporters ahead of her weekly Executive Council meeting, Lam said the government would extend the city’s current social distancing rules beyond Thursday in light of untraceable cases featuring a mutated strain.
