Whooping Cough

Whooping cough — known medically as pertussis — is a highly contagious respiratory tract infection. Although it initially resembles an ordinary cold, whooping cough may eventually turn more serious, particularly in infants. In the more advanced stages, it's marked by a severe, hacking cough followed by a high-pitched intake of breath that sounds like "whoop." The incidence of whooping cough has been increasing, primarily among children too young to have completed the full course of vaccinations and teenagers whose immunity has faded. With proper care, most teenagers and adults recover from whooping cough without complications. Whooping cough is more serious in children, especially infants younger than 6 months of age.
