McHenry County Department of Health reports significant increase in pertussis cases throughout McHenry County
MCHENRY COUNTY, IL – McHenry County Department of Health (MCDH) has reported a significant increase in pertussis (whooping cough) cases, particularly among school-aged children, throughout McHenry County.
Pertussis is a highly contagious bacterial respiratory disease, and early recognition and treatment are crucial to preventing its spread.
Pertussis can start with mild symptoms like a runny nose, low-grade fever, and cough. The cough progresses to intense coughing fits (paroxysmal cough), sometimes accompanied by vomiting, a high-pitched “whoop” sound, exhaustion, and even pauses in breathing (apnea).
The severity and course of the disease can vary based on age and vaccination history. Infants, pregnant women, and individuals with weakened immune systems are at higher risk for severe illness, hospitalization, or even death.
Pertussis spreads through droplets in the air when an infected person coughs or sneezes, especially in close-contact settings like school classrooms. Frequent handwashing and covering coughs and sneezes are important prevention steps.
Anyone who develops symptoms should promptly consult a healthcare provider. If a child is diagnosed with pertussis, parents are encouraged to inform the child’s school to help lessen further spread.
To prevent transmission, those diagnosed with pertussis are advised to take the prescribed antibiotic for five days and remain isolated until the five-day antibiotic treatment has been completed.
Household members and close contacts should also be treated with antibiotics and stay home if they experience symptoms, remaining at home until they have completed the five-day antibiotic treatment. With or without treatment, the cough associated with pertussis can persist for weeks or months.
Vaccination remains the most effective preventive measure against pertussis. While immunity can diminish over time, vaccinated individuals who contract pertussis usually experience milder symptoms.
The MCDH encourages all residents to check with their healthcare provider to ensure vaccinations are up-to-date. Pregnant women should receive the Tdap vaccine during each pregnancy to protect both themselves and their newborns.
The MCDH offers DTaP and Tdap vaccines at a reduced cost for those who qualify. To make an appointment with the MCDH, please call (815) 334-4500, or contact your healthcare provider for vaccination options.
