INDEPENDENCE - Buchanan County health officials are dealing with an outbreak of whooping cough.

Amy Marlow, director of the county's public health department, said five cases have been confirmed but privacy regulations prevent her from identifying where the patients live.

The disease, also called pertussis, is caused by a bacterial infection.

People with pertussis may have cold-like symptoms at first. Within two weeks, a patient will have uncontrollable coughing and may have trouble regaining their breath. Gasping for air may produce a "high-pitched whooping cough," according to the Buchanan County Public Health Department.

The disease is most dangerous to infants and the elderly. Infants could lose their breath, and older patients are at risk of developing pneumonia, Marlow said. However, people of all ages are at risk, she added.

Anyone who has gotten a tetanus shot since 2005 is vaccinated against whooping cough, though the immunization does not provide full protection.

The easiest ways to stop the spread of pertussis is to stay away from large groups of people when sick, wash your hands and do not share drinks or eating utensils. Patients also should take all of their antibiotics.

Individuals who think they came in contact with someone with whooping cough can call the Buchanan County Public Health Department at (319) 332-0860.
