A group of travelers who may have been exposed to the coronavirus in China is arriving in San Antonio today. The Centers for Disease Control announced that the travelers will be housed temporarily at Joint Base San Antonio-Lackland. The base is one of four coronavirus quarantine zones in the nation. A town hall meeting was held last night for military personnel and their families about the use of Lackland as a quarantine zone. San Antonio city officials and public health partners were on hand to answer questions.
