Q

Q

indirect transmission

A

occurs when there is no direct contact with the infected person, but the pathogen is nonetheless transmitted
- when a person comes in contact with the infectious agent through food, water, or an inanimate object such as toys, soiled clothes, or even a computer keyboard

Q

airborne transmission

A

particles (dust or small respiratory droplets) containing microorganisms can remain suspended in air for long periods of time
- these organisms must be capable of surviving for long periods of time outside the body and must be resistant to drying

Q

water-borne diseases

A

more specific subgroup of water related diseases; not only is water required for the transmission of disease, but it is in fact the source of exposure to the susceptible host

Q

key points from rachel carson’s silent spring

A
  • by poisoning nature, people were ultimately poisoning each other and subverting what she considered a fundamental right to a healthy environment
  • pesticides were over abused, weren’t used properly, it wasn’t under control
  • forced people to think about the environment in a new way

A

an infectious disease caused by a virus that mutates frequently, causing new strains to spread around the world regularly; vaccines are effective but must be changed each year

Q

reservoir

A

a place where a pathogen lives and multiplies before invading a noninfected person; some pathogens infect only humans; some have animal reservoirs and infect humans only occasionally. contaminated water or food may serve as a reservoir for waterborne or foodborne diseases

Q

incubation period

Study These Flashcards
A

time between infection of an individual by a pathogen and the manifestation of the disease it causes

21
Q

chain of infection

Study These Flashcards
A

pattern by which an infectious disease is transmitted from person to person
cycle of pathogen, reservoir, place of exit, method of transmission, port of entry, susceptible host

22
Q

how to interrupt chain of infection

Study These Flashcards
A

link 1: pathogen could be killed by for example using an antibiotic
link 2: eliminate the reservoir that harbors the pathogen
link 3: quarantining infected individuals
link 4: resistance of hosts can be increased by immunization

23
Q

significance of outbreak investigation

Study These Flashcards
A

identifies the source of the outbreak and implements measures that can prevent further spread of the outbreak

24
Q

herd immunity

Study These Flashcards
A

protection of individuals who lack immunity to a disease that is provided when a significant majority of the population has been immunized against that disease, either by vaccination or by acquisition of immunity by infection

25
environmental justice
looks at the inequitable distribution of risks associated with an environmental toxicant; environmental injustices thus occur when marginalized populations are over-represented in environmental contaminant exposures, leading to health disparities
26
bioterrorism
terrorism involving the release of toxic biological agents
27
antibiotic resistance
ability of bacteria and other microorganisms to resist the effects of an antibiotic to which they were once sensitive
28
nosocomial surveillance (surveillance of healthcare-associated infections)
obtains national data on nosocomial infections; used to estimate the magnitude of the nosocomial infection problem in the US and to monitor trends in infections and risk factors
29
infectious disease triangle
agent (what causes the disease), host (who harbors the disease), environment (external factors that cause or allow disease transmission)
30
purpose of onehealth
goal to achieve optimal health outcomes, recognizing the interconnections between people, animals, and the environment
31
characteristics of one health approach
approach tackles shared health threats by looking at all angles- human, animal, plant, and environmental - equity between sectors and disciplines - sociopolitical and multicultural parity - socioecological equilibrium that seeks a harmonious balance between human-animal-environment interaction - stewardship and the responsibility of humans to change behavior and adopt sustainable solutions - transdisciplinary and multisectoral collaboration
32
examples of onehealth issues
zoonotic diseases antibiotic resistance food safety and security vector-borne diseases environmental health chronic diseases mental health occupational health
33
world health organization (WHO)
responsible for providing leadership of global health matters, shaping health research agenda, setting norms and standards, articulating evidence-based policy options, providing technical support to countries and monitoring and assessing health trends
34
the league of nations
gather information on epidemic outbreaks; pioneered in the collection, standardization, and dissemination of vital and health health statistics
35
alma-ata declaration
first time representatives from all countries in the world meet for the promotion of health care for all addressed healthcare problems of the poorest countries focused on primary healthcare
36
millennium development goals (MDGs)
generated new and innovative partnerships, galvanized public opinion, and showed the immense value of setting ambitious goals helped to life more than one billion people out of extreme poverty, to make inroads against hunger, to enable more girls than ever before to attend school, and to protect our planet inequalities persist and progress was uneven which led to the SDGs
37
sustainable development goals (SDGs)
had working groups and sought international input has 17 goals include improving all countries, including the high-income countries pillars of human development, human rights, and equity are deeply rooted in SDGs and several targets seven explicitly refer to people with disabilities, six to people in vulnerable situations, and two to non-discrimination include comprehensive vision for partnership and multilateral projects
38
sustainable development goals (17 of them)
no poverty zero hunger good health and well-being quality education gender equality clean water and sanitation affordable and clean energy decent work and economic growth industry, innovation, and infrastructure reduced inequalities sustainable cities and communities responsible consumption and production climate action life below water life on land peace justice and strong institutions, partnerships for the goals
39
health communication
study and use of communication strategies to inform and influence individual and community decisions that enhance health interpersonal or mass communication activities which are focused on improving health of individuals and populations considers a variety of channels to deliver targeted or tailored messages to different audiences
40
why is health communication important?
patient and provider communication public health interventions health behavior changes
41
commonly used health communication channels
podcasts, news outlets, social media, infographics
42
key principles of effective health communication
few in number, short and concise, memorable, focused on a specific topic, consistent
43
health misinformation
linked to 6 domains - vaccines - diets and eating disorders - drugs and new tobacco products - pandemics and communicable diseases - noncommunicable diseases - medical treatments and interventions
44
addressing misinformation
equip individuals with the tools to identify misinformation expand research that deepens our understanding of health misinformation implement product design and policy changes on tech platforms invest in longer-term efforts to build resilience against health misinformation convene federal, state, local, territorial, tribal, private, non profit, and research partners
45
media advocacy
getting news media attention; increasing the odds that coverage supports/reflects community efforts to create a healthier environment
46
different forms of mass media
news, advertisements, entertainment, social media
47
ways the media affects health
