The DeKalb County Health Department (DCHD) is notifying the community of an increase in confirmed and reported pertussis cases, with five cases reported within the last week.
Pertussis, commonly known as “whooping cough,” is a highly contagious respiratory illness that spreads through coughing and sneezing and can cause symptoms that last for weeks or even months. While people of all ages can become ill, pertussis can be especially serious for serious for infants, young children and older adults.
Symptoms usually start five to ten days after being around someone who is sick. Early symptoms may look like a common cold and can include:
- Runny nose
- Sneezing
- Mild fever
- Cough-which may become worse after 1–2 weeks and can include fast coughing fits that may sound like a “whoop.”
After one to two weeks, the cough can become worse and may happen in fast coughing fits.
To help stop the spread of illness:
- Wash your hands often
- Cover your coughs and sneezes
- Stay home when sick
- Stay up-to-date on your vaccines
One of the best ways to protect yourself and your family from pertussis is to stay up to date on vaccines. Talk to your healthcare provider to make sure your vaccinations are current. To learn more about whopping cough, visit the Illinois Department of Health’s website.
