VANCOUVER, Wash. - Clark County's public health officer says the health department has been investigating a growing number of pertussis cases.
Since July, the health department has investigated 38 cases of the illness also known as whooping cough. Of those, 25 are confirmed, five are probable cases and eight are suspect cases.
Dr. Alan Melnick told The Columbian newspaper three of the cases have been in infants, who are at high risk for serious complications, including pneumonia.
Last year, between July 1 and Sept. 30, the Clark County had 12 total cases. In 2008, during the same time period, there were nine cases.
Pertussis vaccines are available for infants and a booster is recommended for people ages 11 and older.
