MEXICO CITY — Mexico President Andrés Manuel López Obrador says he does not plan to get tested for COVID-19, one day after the announcement that a high-ranking member of his administration he’d recently been in contact with was infected.

Zoé Robledo, director of Mexico’s social security system, announced Sunday night that he had tested positive, two days after he appeared with López Obrador at an event in the Tabasco state capital of Villahermosa. The president’s security cabinet had also been present during that event.

López Obrador returned to the capital Sunday after a week-long tour of the country’s southeast. He used the trip to kick off construction of a tourist train, one of his signature projects, and to illustrate the government’s efforts to reactivate the economy.
