Law firms and multinational corporations in Mexico say they are taking precautions to protect their staff from the spread of COVID-19 and are busy advising clients, despite the decision by Mexican officials to keep its borders open to international travelers — even as the U.S. and several other countries in Latin America impose temporary bans on European arrivals.

Ana López Mestre, a lawyer and director of the American Chamber of Commerce in Mexico, said Wednesday that the group’s 1,400 members are adopting corporate guidelines such as avoiding unnecessary international trips.
