While anticipating a possible second wave of measles patients, NIU health officials are vaccinating those willing to pay a $15 fee or those vaccinated before 15 months of age.

Because the 12 NIU students who contracted hard measles at a sorority dance in Rockford Oct. 21 were contagious before symptoms appeared, the possibility exists of a second generation of measles patients, said Marilyn Jesser, communicable disease program coordinator at the DeKalb County Health Department.

“The strength of the possibility depends on the number of contacts the first generation made,” Jesser said.

Although those aware of their exposure to the 12 patients might have been revaccinated, Jesser said time is critical in preventing severity of symptoms. “The 72-hour period right after exposure is the most critical for preventing symptoms,” she said.

The initial 300 doses of vaccine were donated by the Illinois Department of Health and rationed according to state regulations. After the first measles diagnosis Nov. 8, the University Health Service and the health department last Friday treated members of NIU fraternities and sororities who met one of two requirements. Shots were given only to those vaccinated before 15 months of age or unsure of their last vaccination.

Rosemary Lane, health center director, said the center purchased 500 doses of vaccine and has ordered another 100. These doses will not be rationed as the initial 300 were.

Lane estimated 200 people were vaccinated Thursday. Lane said 70 doses of the state vaccine remain for those meeting the requirements.

Measles symptoms include fever, runny nose, coughing, watery eyes and a rash which usually first appears on the face or neck. Jesser said those showing symptoms will cease to be contagious four days after the rash appears and will recuperate soon after.
