The United Nations estimates that by over the year 2050 more than ________ of the worlds population will live in urban areas.

69%

a disease newly identified in the population or one which exists but has changed.

Emerging infectious disease

network of networks to provide early warning of emerging threats.

Global disease surveillance

to reduce HIV/AIDS by 25%, deaths due to tuberculosis and malaria, CDC also to work with Global Alliance for vaccines to enhance delivery and use of new vaccines against respiratory illnesses and other childhood diseases.

Global initiatives for disease control

Acanthamebiasis is a group ____ emerging/ reemerging infectious disease.

I

includes follow-up assistance to maintain control of new pathogens after the outbreak.

International outbreak assistance

older diseases that were previously under control but are reoccurring.

Reemerging infectious diseases

which of the following diseases can be transmitted by a tick?

Tularemia

The establishment and further spreading of an infectious disease within a new population is a process called:

adoption

bacillus anthracis, group III transmission-cutaneous, inhalation, and gastrointestinal

anthrax

mostly in developing countries and inner cities of the industrialized world inadequate vaccination programs

breakdown of public health measures

tsunamis, hurricanes, earthquakes, volcanic eruptions will force microbes to adapt to the new organisms that are capable of causing a new disease or the reemergence of old, disease-causing strains.

climate,weather, and natural disasters

bioterrorism and biowarfare

intent to harm

travelers infected w/ exotic disease food and various products imported from other countries

international travel and commerce

into new geographical territories such as rapid spread of the west nile virus in the united states.

known agent

constantly evolving they adapt quickly to adverse environments antimicrobial resistance due to overuse of antimicrobial drugs

microbial adaptation and change

which of the following diseases is considered to fall in the group II category?

mumps

such as genital, respiratory, and cardiac

new manifestations

which of the following diseases is transmitted by fecal-oral route?

peptic ulcer

yersinia pestis, group III transmission-flea bites

plaque

malnutrition, poor living conditions

poverty

these centers will integrate disease surveillance, applied research, and prevention and control activities in developing countries.

public health training w/ CDC support

variola virus, group III transmission- person to person, infected aerosols, face to face contact w/ infected person after fever has begun.

small pox

globalization, bulk processing for human consumption- increased risk to introduce microbes from different areas of the world animal feed ingredients

technology and industry

Which of the following infectious diseases is considered to be a reemerging disease?

tuberculosis

destruction of water supplies, malnutrition, collapse of public healthcare system

war and famine

(hantavirus, ebola, and AIDS) newly emerging

group I

reemerging pathogens such as tuberculosis and malaria

group II

agents w/ bioterrorism potential, subdivided into categories A, B, and C.

group III

which if the following infectious disease is considered a newly emerging disease?

hantavirus

which of the following diseases is considered to fall in the group I category?

helicobacter pylori

due to migration or war due to economic conditions urbanization increasing age of population

human demographics and behavior

"fifth disease" is caused by

human papillovirus B19

ex) compromised immune system due to HIV

human susceptibility to infection

identified and shared with the international community.

Application of proven public health tools

includes follow-up assistance to maintain control of new pathogen after the outbreak.

Applied research on diseases of global importance

the lead federal agency whose primary responsibility is protect the people of the United States from infections diseases is the _______

CDC

small changes in the viral coat that happen over time are referred to as an antigenic ____________.

drift

changes in agricultural practices economic development changes in land use

ecological changes and agricultural development

_______________________of new infectious diseases include human demographics and behavior, ecological changes and agricultural development, international travel and commerce, technology and industry, and microbial adaptation and change, and breakdown of public health measures.

factors responsible for emergence

the Hendra virus is transmitted by ___________

flying foxes

the Marburg virus was originally spread by:

green monkeys
