An octogenarian is the ninth presumptive case of COVID-19 in Dallas County.

The Dallas resident has a travel history and is being treated at a local hospital, the Dallas County Department of Public Health announced Friday evening.

Starting Saturday, the health department will release information on new cases at about 10 a.m. daily, county Judge Clay Jenkins said.

The announcement comes less than 24 hours after Jenkins issued a declaration of local disaster and banned large-scale gatherings. While not prohibited, Jenkins has asked individuals to limit social gatherings of all sizes for the foreseeable future.

The county reported five more cases of COVID-19 on Thursday. One of the patients had no recent travel history, making it a possible case of community spread. Two of those people were hospitalized while three were isolated at home. The prior three cases involve an out-of-state 77-year-old man, his acquaintance and an Irving church leader.

Jenkins urged collective action in a taped interview that will air Sunday on Lone Star Politics, a political show produced by KXAS-TV (NBC5) and The Dallas Morning News.

“Everything you do — you need to exercise personal responsibility and ask yourself, ‘Is it worth the risk?’” Jenkins said. “If you feel well and you’re over 60 years old, you shouldn’t be around groups of even over 10 people.”

Individuals over 60 and those with pre-existing conditions are the most at risk to the new virus.
