New Health risk in 21st Century
Bioterrorism Anthrax Letters In 2001, lethal anthrax spores were placed in letters in the U.S. mail 22 people were infected, 5 of them dies.
16
SARS
In 2003 first new severe disease reveled our vulnerability It can spread person to person, with no vector Incubates silently for more than a week, Mimics symptoms of other diseases Takes heavies toll on hospital staff and kills10% of those infected. Can easily spread through air travel
16
Global Public Health security
Partnerships must exist amongst countries to achieve this. All countries need to implement the IHR (International Health Regulations), Cooperate in the surveillance and outbreak alert and response Openly share knowledge, technologies and materials Increase training for public health personnel
16
1. In the 21st century, describe why infectious diseases pose a greater threat to the global population.
-climate change -increased global travel and urbanization (rapid spread across border) -bioterrorism (anthrax)/inventions of other biochemical weapons
17
3. What in the role of GOARN?
-coordinating international responses to disease outbreaks and public health emergencies -facilities resources fast and experts in affected areas -preventing spread across borders
17
2. In history, there are 3 major landmarks in public health that is still very relevant today. Describe the impact of the following public health landmarks at their time in history and their importance to today’s public health.
-Quarantine (isolation of ppl with disease, reduced spread of COVID, at the time prevented epidemics such as plague, saved lives) -Sanitation (snow created during cholera outbreak, clean water ad proper waste disposal preventing spread, and is used in healthcare all the time now) -Immunization (reduced deadly disease almost eradicated stuff like polio and smallpox, still kids are given it save lives prevent illness)
17
example of Epidemic
Ex. AIDS in Africa or AIDS in intravenous drug users
18
- separation and restriction of movement who are not ill but who may have been exposed to infection, in order to prevent further transmission of disease. Can involve close contact with ill person, such as family, social events, airplanes, health care workers. If an entire community is quarantined, it is called cordon sanitaire
Quarantine
18
4. Why is it crucial to have collaboration between donor and recipient countries?
-ensures that resources are allocated effectively and efficiently -donor countries provide funding, expertise and tech while recipient countries offer local knowledge which promotes sustainability
18
5. WHO established the ChemiNet in 2002. Why was it established?
-To enhance global cooperation and coordination in responding to chemical incidents and emergencies -Chemical Incident alert and Response System Coordinates resources to respond to chemical incidents, Also monitors for the release of chemicals, and assists in recovery.
18
6. Enforcing borders controls is not effective way to stop the spread of disease in today’s world. How can the spread of disease be prevented?
-promoting vaccines -bettering global surveillance systems to detect outbreak -educate on safety, washing hands -investing in health programs and centres
19
a disease that occurs in a certain place or group of people Polio in Afghanistan
Endemic
19
affects more than the expected number of cases of disease occurring in a community or region during a given period of time. A sudden severe outbreak within a region or a group.
Epidemic
20
refers to the sudden increase in the number of cases of a disease
outbreak
21
- contacting all people that was in contact with a person who has tested positive to ensure all precautions are taken to prevent the spread of the disease
Contact tracing
21
example of Pandemic
Ex. H1N1 COVID 19 Note: WHO- World Health Organization
21
ex of outbreak

22
Phases of an Pandemic
WHO has identified 6 phases of a pandemic, subdivided into 3 periods. Inter pandemic Period- Phases 1 and 2 Pandemic Alert Period- Phases 3, 4 and 5 Pandemic Period- Phase 6
22
An epidemic (a sudden outbreak) that becomes very widespread and affects a whole region, a continent, or the world.
Pandemic
22
Ability of a virus to move from poultry to wild birds and back again, or to other species (humans, pigs)
Relay transmission
22
- separation and restriction of movement of people who are ill with an infectious disease.
Isolation
23
- maintaining a distance of 2m or 6ft between you and other people.
Social distancing
23
-Minor genetic changes in virus -Reason why flu vaccines must be reformulated every year for the seasonal flu.
Antigenic drift
24
Interpandemic Period: Phase 1- Phase 2 -
Phase 1 Informs us no animal influenza virus is currently detected in humans. If virus is present in animals, risk of human infection is low Phase 2 No animal influenza detected in humans A animal influenza virus is circulating and increases the risk of human infection
25
WHO goals and responses during Phases 1 and 2
Goal Strengthen global, national and local preparedness Minimize risk of transmission to humans Responses Improve farming practices Enhance animal surveillance Investigate suspect cases
26
Pandemic Alert: Phase 3 -
A group or cluster of people is affected by a strain of influenza that is not caused by person to person transmission.
27
Goals and responses During Phases 3
Goal- to characterized new virus subtype and contain virus Response Consider culling and vaccinating animal source (kill all of them) Isolating human infections Use of antivirals
28
Pandemic Alert Phase 4
Small clusters resulting in limited spread from person to person, causing local outbreaks in communities
29
Goals and responses during Phase 4
Goal- contain virus and delay spread Response Continue containment; restrict travel, quarantine, use of antiviral medications Speed up vaccine development
30
Pandemic Alert: Phase 5 -
Human to human spread(outbreaks) has occurred in at least two countries in one WHO region Suggesting virus is better adapted to humans, but not fully transmissible
31
Goal and responses During Phases 5
Goal- contain and delay spread to avert pandemic and to gain time to implement pandemic measures Response Continue containment, antiviral medications Restrict travel Consider community containment if necessary
32
Pandemic period: Phase 6 -
Considered the true “pandemic phase” with community level outbreaks in at least one other country in a different region that was originally noted in phase 5 Virus is widespread and containment measures is no longer effective Pandemic starts to subside with decreasing number of cases and possibly good vaccine coverage
33
Goals and responses during Phase 6
Goal- to minimize impact of pandemic Response Continue containment, isolation and/or quarantine as needed Continue to administer antiviral medications as per priority groups Immunize when vaccines comes available Actively monitor high- risks areas
34
Infection levels drop below peak levels and spread has slowed down
Post Pandemic Peak Period
35
WHO Action Plan During Post Peak Period
Plan and coordinate for resources for possible future waves Continue surveillance to detect future waves Continue to update the public Evaluate the effectiveness of the measures taken Rest, restock, and rebuild essential services
35
Infection levels drops to level normally seen for the regular seasonal influenza
Post Pandemic Period
36
WHO Action Plan During Post Pandemic Period
Review lessons learned and share experiences Replenish resources Evaluate all interventions implemented Evaluate the response of the health system to the pandemic
