2009 H1N1 Achievements

Rapidly identified novel influenza virus Developed and distributed diagnostic

reagents within weeks of detection Vaccinated approx 80m US residents Increased use of antiviral drugs for severely

ill

19

Learning from the 2009 Pandemic

Preparation paid dividends Vaccine production inadequate

Time to sufficient quantities Understanding what was available Communicating the uncertainty

Everyday systems work best Importance of communications

20

Communications Within government With partners With the public

Infection control Travel issues Coordination with State and Local Health

authorities (and political leadership) Potential for societal impacts

Key Items for ImprovementPandemic Preparedness Continues: Plan, Exercise and

Refine PlansVaccine

ProductionModernize and increase speed of vaccine production

Laboratory Diagnostics

Communications

Antiviral Drug Distribution

Staffing

Infection Control

Modeling

Improve lab diagnostics, including next generation serologic testing and more sensitive point-of-care testing

Clearly define and express severity for seasonal and pandemic influenza

Leverage existing commercial drug distribution to efficiently distribute antivirals

Effectively manage the emergency response staffing

Improve infection control, especially respiratory protection

Integrate statistical modeling into the response

BudgetIncrease proactive budget planning to facilitate fast, efficient use of resources

2014 Ebola Outbreak Response

EBOLA

2014 Ebola Outbreak

First discovered in 1976 near the Ebola River in the Democratic Republic of the Congo

Family of zoonotic RNA viruses Filoviridae

Historically, death rates for Ebola 50%-90%

History of Ebola

The 2014 outbreak is the largest Ebola outbreak in History and the world’s first Ebola epidemichttp://www.cdc.gov/vhf/ebola/outbreaks/2014-west-

Ebola Response Priority Objectives

US Government Strategy

Encourage International Participation

Control the Outbreak

Build Long-term Capacity to Detect

and Respond

Mitigate Secondary Impacts

30

Challenges in West Africa

Epicenter of epidemic in remote, tri-country border area, rapid spread in urban areas

Institutions of government still being strengthened

Weak health and public health systems Lack of even basic resources Poor communications (limited cell phone,

radio coverage, internet service) Divisions within societies recovering from

war Misconceptions about disease and low

levels of literacy

31

Laboratory Testing Capacity

Sierra Leone 300 specimens per day

Liberia 350 specimens per day

Guinea 100 specimens per day

* Lab Partners in West Africa include: US CDC, NIH, China CDC, Institute Pasteur, Canada, CDC, NIH, US Navy, US Army, Russia, European Consortium, South Africa

Recent Developments: Texas Cases Texas case #1

First domestically-diagnosed Ebola patient confirmed 9/30/14

Visited ER, evaluated and sent home on 9/26/14 14 person CDC team provided support with contact

identification and tracing and infection control—48 contacts tracked

Texas case #2 Diagnosed 10/12/14 Isolated within 90 minutes of reporting symptoms Provided patient care to case #1, not a contact between

2 ER visits Review of infection control procedures Few contacts, but over 70 health care workers being

monitored Texas case #3

Tested positive for Ebola on 10/15/14 33

Domestic Preparedness:Airport Screenings

Entry screening of passengers arriving from affected countries JFK: New York-JFK, NY (10/12/14) IAD: Washington-Dulles, VA EWR: Newark, NJ ORD: Chicago-O’Hare, IL ATL: Atlanta, GA

Account for 94% of all passengers arriving from Liberia, Sierra Leone, and Guinea

Procedure Visual assessment Questions about symptoms Temperature measurement Questions about exposure

34

Applying Lessons Learned from Influenza Responses

Structure of response leadership Importance of communication

Potential for misinformation / distrust CDC product is information and guidance No vaccine or specific therapeutic agent Critical role for meticulous infection control Community mitigation measures

35

Preparing for Emergencies of Infectious Diseases

Global detection and response is key Plan and exercise for greatest threats

(pandemic influenza) Recognize the need for speed and scale Communication capacity
