◉ Viral infections can damage ? epithelium that would normally
clean the incoming air, ? airways making it hard to move gasses, and
lead to secondary ? infections due to the static mucus providing a
route for infection.
Answer: bronchial, obstruct, bacterial
◉ The common cold is a viral infection of the ? respiratory tract.
Answer: upper
◉ Outbreaks of colds due to ? are most common in early fall and late
spring.
Answer: rhinoviruses
◉ ? are popular over-the-counter treatments for colds because of
their action in drying nasal secretions.

influenza virus.
Answer: hemagglutinin, neuraminidase
◉ The influenza viruses can cause three types of infections: an
uncomplicated ? respiratory infections, ? pneumonia, and a

Answer: upper, viral, bacterial
◉ Because influenza is so highly contagious prevention relies
primarily on ?.
Answer: vaccination
