MEXICO CITY (AP) - The governor of the Mexican border state of Tamaulipas said Thursday he has tested positive for COVID-19, becoming the fourth state leader in the country to be infected by the new coronavirus.

Gov. Francisco Cabeza de Vaca said on his official Twitter account that he will continue working and noted that the state south of Texas is passing through “a critical moment of infections.”

The state has recorded more than 6,000 confirmed cases and at least 356 deaths, though low rates of testing mean the actual number of infections is belived to be vastly higher.

México as a whole has reported more than 231.000 casos of COVID-19 and 28.510 deaths.
