This Essential Public Health Service focuses on evaluating and improving public health systems.

What is the essential Public Health Service 10

This is how influenza is spread, and these are the body parts it affects. 

What are respiratory droplets? What is the respiratory system (the nose, throat, and lungs)?


100

This many people died worldwide from the 2009 H1N1 pandemic

What is approximately 18,000?

100

This federally managed resource is designed to deploy within 12 hours to supplement local health supplies, but in 2009 lacked ventilators and was dependent on inconsistent state-level distribution plans.

What is the Strategic National Stockpile (SNS)?

100

The unfair difference in health outcomes and access to healthcare between different racial groups

What is health inequity?

200

EPHS #10 helps to identify this kind of limitation in a pandemic response 

What are the systemic failures and inefficiencies? 

200

Despite being a type of influenza virus, the 2009 H1N1 strain had an unusual epidemiological feature: it disproportionately affected this age group, unlike seasonal flu, which typically impacts the elderly.

What are children and young adults under the age of 25?

200

This term refers to the initial, rapid spread of the 2009 H1N1 influenza pandemic, which was caused by a novel strain containing human, avian, and swine genetic components. Despite widespread fear, it was ultimately much less catastrophic than initially predicted, with global deaths estimated at around 18,000.

What is the "swine flu"?


200

During the H1N1 pandemic, this major vulnerability, increased by the worried well and predictable human behavior, led some U.S. hospitals to create triage areas in parking garages, highlighting the dire need for a national initiative aligned with the National Planning Scenarios.

What is the inability to manage healthcare surge capacity?

200

This special population relies on more medical, mobility, and social support services during the pandemic. 

What is the immunocompromised population, rural Communities, and elderly population?

300

EPHS #10 encourages agencies to learn from these, and it is also taken into consideration during pandemic preparedness.

What are past mistakes, ways to improve, and the outcomes? 

300

The 2009 H1N1 virus was an unusual mix of genetic material from these three sources. 

What are swine, avian, and human influenza viruses?

300

The WHO declared H1N1 a pandemic in this month of 2009, and this country was the first to identify the 2009 H1N1 virus.  

 What is June and Mexico? 


300

In 2009, pandemic flu planning was hampered by this systemic issue, where 58 U.S. state and territory preparedness plans shared no standard format, approach, or mission structure.

What is the lack of commonality in state and local pandemic preparedness plans?,

what is unified diaster preparedness planning in the nation?

300

This deals with the flaws in the plans made to manage medically dependent and immobile individuals, the plans involve unfair plans like shelter-in-place and limits on movement. 

What is failure to sustain special needs populations?

400

The Essential Public Health Service #10 requires the collaboration of these major stakeholders. 

What are Public health experts, disaster planning managers, scientists, policy makers, and community partners?

400

Despite assumptions that the pandemic would occur in multiple 8–12 week waves, H1N1 spread rapidly due to this modern global factor, which compressed the outbreak period and defied traditional epidemiological expectations.


What is international air travel as a vector accelerant?


400

In 2009, the WHO declared the H1N1 pandemic. One of the key responses to this pandemic involved a rapid decision to develop a vaccine based on the initial characterization of the virus. This decision was made despite the risks of developing a vaccine that might not be effective against a more deadly strain. The development process was aimed at meeting this timeline, ideally before this event occurred in the Northern Hemisphere.



What is the goal of having the H1N1 vaccine ready by the start of the school year in September 2009?


400

In the event of a nationwide respiratory illness surge, this specific gap in the U.S. Strategic National Stockpile's tertiary care preparedness, stemming from the absence of a centralized requirements-determination process, contributed to local-level resource planning failures and a critical shortage of these life-saving hospital devices.

what is assisted breathing apparatus (ventilator)?

400

During a pandemic, these three critical social determinants of health are often disrupted, leading to increased health inequities when individuals face job loss and isolation.

What are access to social support, healthy food, and housing?

500

The application of Essential Public Health Service#10 to the 2009 H1N1 case revealed the weakness in pandemic response faced in every state. 

What is the lack of a unified national emergency preparedness?

500

This critical process typically takes 18 months to complete and involves strain characterization, vaccine development, production, and distribution. It was especially challenged during the 2009 H1N1 pandemic due to the novel virus strain.

What is the vaccine development process for influenza?

500

This strategy, borrowed from smallpox eradication efforts, was initially considered a key component in managing the 2009 H1N1 pandemic by containing outbreaks through targeted vaccination of surrounding areas. However, it was ultimately abandoned as human-to-human transmission and intercontinental travel made containment nearly impossible.

What is the concentric ring vaccination strategy?


500

 In response to the 2009 H1N1 pandemic, the United States initially allocated 30% of the vaccine production to the US phamarceutical companies and the remaining 70% was awarded to foreign phamarceutical comapnies risking the lives of many American by placing it in the hands of foreign government forgetting the risk of pontential pandemic crisis. 

 What is an export embargo on vaccines by foreign governments inorder to protect their citizens?

500

This infectious disease is in relation to a virus that requires a much larger paradigm shift in emergency response, especially for vulnerable populations, due to its severe respiratory symptoms, high hospitalization rates, and the need for long-term sustainment strategies like home-based care and mass vaccination, it also shows the systemic issues that is affecting different communities.
