Patients diagnosed with COVID-19 have reportedly had mild to severe respiratory illness with symptoms of fever, cough, and shortness of breath. Symptoms may appear in as few as 2 days or as long as 14 days after exposure. However, some patients can have more severe symptoms, complications, and/or death.

The most updated COVID-19 recommendations guide individuals with mild symptoms to stay home and self-isolate until all three of the following have happened:

· You have had no fever for at least 72 hours without the use of fever-reducing medicine.

· Other symptoms have improved.

· At least 7 days have passed since your symptoms first appeared.

Should symptoms worsen, please call your provider before arriving to the provider’s office or emergency department to limit the potential spread of any infection.

DCPH is identifying and contacting individuals who may have been exposed. Any individuals identified as having been exposed will be contacted directly by DCPH. No further personal information will be released to protect patient confidentiality.

DCPH recommends the following preventive actions to help prevent the spread of respiratory viruses:
