Routes of Transmission 
On this page:
Airborne
  • Tuberculosis - Tuberculosis (TB) is a bacterial disease primarily of the lungs. It is airborne and spreads when someone with active TB disease coughs, laughs or sings.

Animals

Public health for veterinarians. The human-animal connection. Many microbes that threaten public health are carried by animals and transmitted to humans. These pages highlight these organisms which animals carry them, and the illnesses they cause:


Food and Water

Food and water; necessary for life, but liable to contamination with harmful microbes. These links highlight microbes that can be transmitted by food and water and links to programs aimed at minimizing those risks:

  • FoodNet (Foodborne Illness):
    The Foodborne Diseases Active Surveillance Network (FoodNet) is the foodborne disease component of the CDC's Emerging Infections Program (EIP). FoodNet, established in 1995, is a collaborative project among CDC, seven EIP sites including Oregon, the U.S. Department of Agriculture (USDA), and the U.S. Food and Drug Administration (FDA). The project consists of active surveillance for foodborne diseases and related epidemiologic studies designed to help public health officials better understand the epidemiology of foodborne diseases in the United States. The FoodNet program tracks foodborne illness using surveys of physicians and laboratories, case-control studies, and active case finding of the following pathogens: Campylobacter, Cyptosporidium, Cyclospora, E. coli 0157, Listeria, Salmonella, Shigella, Vibrio, and Yersinia.

Health care

Doctors and hospitals are where the sick people go; and unfortunately, some infections may be transmitted in these settings. This page is your gateway to data on healthcare-acquired infections in Oregon. There are rules related to the handling of potentially infectious medical waste:


Respiratory

Some disease-causing bacteria and viruses are carried in the mouth, nose, throat and respiratory tree; they can spread by coughing, sneezing, or through saliva or mucus on unwashed hands. Browse these links to diseases caused by these microbes:
