With the addition of five more deaths Thursday, more than 100 people have now died in Dallas County after contracting COVID-19, this according to county health officials who also say another 179 people have been infected with the deadly virus.

Dallas County Health and Human Services reported Thursday 3,531 confirmed cases of the coronavirus and 104 COVID-19 related deaths.

“Today is our highest number of daily reported COVID-19 positive cases thus far. DCHHS epidemiologists tell us that the increase stems from a change in CDC guidelines allowing our front line workers like grocery store and big box store employees to be tested without symptoms at our drive-through locations,” said Dallas County Judge Clay Jenkins an a prepared statement. “We also lost another five residents yesterday to COVID-19.”

Of the five most recent deaths, two were people who had been hospitalized, including a man in his 20s from Balch Springs and a man in his 60s from Dallas, while the three others were residents of long-term care facilities in Dallas who ranged in age from their 70s to 90s.

Of the cases requiring hospitalization who reported for employment, the county said 79% of them have been critical infrastructure workers coming from a broad range of occupational sectors including healthcare, transportation, food and agriculture, public works, finance, communications, clergy, first responders and other essential job functions. Most cases involving hospitalization involve patients over the age of 60 with a high-risk condition.
