Whooping cough is highly contagious, and quickly spreads by coughing or sneezing.
The symptoms are usually similar to that of a common cold, but steadly get worse over the course of a week or two.
Parents are urged to take their child to the doctor if they have any cold symptoms to make sure it is just a cold.
They also say anyone with questions can contact the school nurse, their doctor or the state department of health.
