State officials have announced another positive test result for COVID-19 in Johnson County, according to information provided by the Iowa Department of Public Health.

One other case has been detected in Pottawattamie County in western Iowa, bringing the state's total to 14.

Symptoms of COVID-19 include fever, dry cough, and shortness of breath. People of advanced ages are more at risk to contract and develop complications from the virus, along with those that have underlying health conditions, according to state officials.

Steps that can be taken to help prevent contracting coronavirus are similar to those that help prevent any other infectious disease spread: cover your cough or sneeze using a tissue or directed into your elbow, frequent hand washing using soap and water for at least 20 seconds, and stay home when you feel sick. People should also avoid touching their face, and cleaning of frequently-touched surfaces with disinfectants are recommended.

The CDC does not recommend the use of face masks, according to the Iowa Department of Public Health.

Iowans who have questions about coronavirus may call 2-1-1 to access a hotline available 24 hours a day.

Another update from the Department of Public Health will be provided on Thursday.
