Whooping Cough Cases Grow in DuPage County

In a letter sent out to area schools on Nov. 30, the DuPage County Health Department (DCHD) warned that several states have recently seen an increase, or localized outbreaks of pertussis, a disease more commonly known as whooping cough.

So far this year, David Hass, public information officer for the DCHD said the county has record 57 cases, up from 26 cases in 2009 and 13 cases in 2008.

"We're getting it out there and informing the schools," Hass said. "Our goal is to contain it."

While pertussis is highly infectious, DCHD officials say, the symptoms are generally mild. The illness is transmitted through coughing and sneezing and symptoms generally appear five to 10 days after exposure. Symptoms begin with a mild fever and a mild, occasional cough lasting for at least two weeks. But symptoms can become severe, which the DCHD says results in spasmodic coughing that gives whooping cough its distinctive sound.

Generally the disease is mild in older children and adults, Hass said, but it becomes more complicated for older adults, young children and infants, especially those who have incomplete immunizations or no immunizations at all.

"The majority of the cases we are seeing in DuPage are younger than 18 (years of age)," Hass said. "In the younger age group, even the vaccine doesn't protect 100 percent of people," Hass said, but added that for people in high-risk groups, it was important to be vaccinated.

Hass said it was important for people exhibiting symptoms to stay home from school and work to stop the spread of the disease. Pertussis is easily treated with antibiotics, Hass said, but isolation must continue for at least five days after the start of treatment.

No cases have been reported at Lisle Community School District 202 schools yet. District representative Ron Logeman said that school nurses "are just in a monitoring mode at this point."

The schools discuss good health habits—like handwashing—with students, and have several resources on their web site to determine whether a child should be kept home from school.

The last major outbreak of whooping cough in DuPage Count was in 2004, with 127 cases reported.
