communicable disease

Communicable diseases are caused by viruses or bacteria that are spread from one
person to another through a variety of ways. Diseases can be transmitted during air
travel through: direct contact with a sick person, respiratory droplet spread from a
sick person sneezing or coughing, contact with blood and bodily fluids; breathing in an airborne virus; or by being bitten by an insect.

The Communicable Disease program serves as a resource for the general public,
schools and day cares as well as community and medical entities regarding
infectious diseases, infection control and prevention and pandemic preparedness.
