A3: Reservoirs of infection​

What type disease transmission involves an animal "carrier" 

• Person-to-Person
• Animal-to-Person
• Environmental Reservoirs 
• Vector-borne 

Which are examples of Environmental Reservoirs for diseases/ infectious agents? (mark all that apply)

• Contaminated food

• Soil

• Water

• Fomites

Carriers are dangerous because they exhibit  all of the following EXCEPT:

• Asymptomatic (don't show symptoms)
• Are unaware they are spreading the dsease

Mosquitos, ticks and flies are all examples of :

• Fomites

• Vectors

• Viruses

• Environmental Reservoirs

Why can carriers of disease be more dangerous than cases?

• Don't show symptoms

• COMPLETELY aware they are spreading the disease

• Difficult to discover

• Can infect MANY MORE people

Some animal populations, soil, water and even human populations may be considered _________________ for pathogens.

• Fomites

• Vectors

• Reservoirs

• All of the above

What is definition of germ?

• The body responsible for identifying and fighting off unwanted bacteria, viruses, and other bugs.

• A microorganism that can make a person sick. The four major types of germs are bacteria, viruses, fungi, and protozoa.

• Infectious nonliving agents much smaller than bacteria that invade cells and cause diseases such as the common cold and measles.

• Tiny, one-celled organisms that get nutrients from their environment in order to live.

What type of environment is best for the growth of most microorganisms?

• Hot and dry
• Sunny, cold and dry
