The additional death being reported today is of a man in his 80’s who was a resident of the City of Garland. He had been critically ill in an area hospital, and had underlying high risk health conditions.

The provisional 7-day average daily new confirmed and probable cases (by date of test collection) for CDC week 37 was 240, a decrease from the previous daily average of 279 for CDC week 36. The percentage of respiratory specimens testing positive for SARS-CoV-2 remains high with 10.0% of symptomatic patients presenting to area hospitals testing positive in week 37.

A provisional total of 156 confirmed and probable COVID-19 cases were diagnosed in school-aged children (5 to 17 years) during CDC week 37 (week ending 9/12/2020), an increase from the previous week for this age group. The percentage of cases occurring in young adults aged 18 to 22 years has increased to 14% over the past 2 weeks.

Of all confirmed cases requiring hospitalization to date, more than two-thirds have been under 65 years of age. Diabetes has been an underlying high-risk health condition reported in about a third of all hospitalized patients with COVID-19. Of the total confirmed deaths reported to date, about 25% have been associated with long-term care facilities. New cases are being reported as a daily aggregate, with a more detailed summary report updated Tuesdays and Fridays.

Local health experts use hospitalizations, ICU admissions, and ER visits as three of the key indicators in determining the COVID-19 Risk Level (color-coded risk) and corresponding guidelines for activities during our COVID-19 response. Due to weekend reporting, new data will be available on Tuesday, September 22, 2020.

UPDATED – Dallas County Health and Human Services Novel Coronavirus (COVID-19) Summary – September 15, 2020

Specific Guidance for the Public:

The Centers for Disease Control and Prevention (CDC) recommends taking everyday preventive actions to help prevent the spread of respiratory diseases, including:

  • Avoid close contact outside your home: Put 6 feet of distance between yourself and people who don’t live in your household.
  • Cover your mouth and nose with a cloth face cover when around others and continue to keep about 6 feet between yourself and others. The cloth face cover is not a substitute for social distancing.
  • Stay home when you are sick, except to seek medical care
  • Wash your hands often and with soap and water for at least 20 seconds and help young children to do the same. If soap and water are not available, use an alcohol-base hand sanitizer with at least 60% alcohol.
  • Avoid touching your eyes, nose, and mouth with unwashed hands.
  • Avoid close contact with people who are sick.
  • Clean and disinfect frequently touched objects and surfaces daily using a regular household cleaning spray or wipes.
  • Cover your cough or sneeze with a tissue, then throw the tissue in the trash. If you do not have a tissue, use your sleeve, not your hands. Immediately wash your hands.
  • Monitor your health daily. Be alert for symptoms. Take your temperature and follow CDC guidance if symptoms develop.
