are No Less Threatening

Consider these World Health Organization statistics:



One-third of the world's population is infected with tuberculosis, and

2 million die from the disease each year. As many as 79% of new

TB infections are "superstrains," resistant to the most common

therapies.



Some 42 million people are HIV positive, and 3.1 million die from

AIDS each year.



Between 3 million and 5 million new cases of influenza are reported

each year, contributing to 250,000 deaths worldwide.



170 million people are chronically infected with the hepatitis C virus,

and 3-4 million are newly infected each year.

How Bad Was SARS

2003 SARS outbreak appeared to originate in China



Ontario: 375 contacted SARS and 44 died



Demonstrated that earlier warning signs were ignored.



Demonstrated that identified faults were not corrected.



Roughly 30% of quarantined individuals suffered sxs

of PTSD and depression. Duration of quarantine was

significantly related to increase in PTSD sxs.

Civic Duty and not legal consequences was the

primary motivation for compliance.



Public Cooperation depends on public

confidence that public health decisions are

made on an independent medical basis



Public Cooperation depends upon public

understanding of what is necessary and the

authorities are keeping everyone informed of

what is happening

Pandemic Planning Assumptions

DHHS and the White House Homeland Security

Council (HSC) utilizing historical data from this

century’s pandemics estimated about 20-30% of the

population would be ill. Worst case scenario 40%.

Spread of the Pan flu would be comparable to past

pandemics and the length of the outbreak would be

about 6-8 weeks in a given community.

Even if 30% of a community gets sick, the illness

would be spread over an 6-8 week period. The

average duration of the illness is 10 days.

Even in peak times it is likely that no more than 10%

of the community would be ill at any one time. (caring for

sick family members will raise the absentee rate)

Planning Assumptions: Health Care

• 50% of ill persons will seek medical care

• Hospitalization and deaths will depend on the

virulence of the virus





Moderate (1957-like) Severe (1918-like)

Illness 90 million (30%) 90 million (30%)

Outpatient medical care 45 million (50%) 45 million (50%)

Hospitalization 865,000 9, 900,000

ICU care 128,750 1,485,000

Mechanical ventilation 64,875 745,500

Influenza Antiviral Drugs and Medical

Supplies

Strategy

– Procure 81 million courses

of antivirals

6 million courses to be used

to contain an initial U.S.

outbreak

75 million courses to treat 25

percent of U.S. population





Accelerate development

of promising new antiviral

drugs

Disease Mitigation Measures

Hand washing and respiratory etiquette

Social distancing including the prohibition of

social gatherings

Travel restrictions

Use of masks

Use of antiviral medications

Use of Isolation (confinement of symptomatic patients so they

won’t infect others)

Use of voluntary or involuntary quarantine (the

separation of asymptomic people who may have been exposed to infection

and may or may not become ill)

School closures

Disease Mitigation Measures Feasibility

Hand washing and respiratory etiquette

The influenza virus survives on your hand for 5 minutes or less. This

mitigating measure is advisable.



Social Distancing:

The recommendation is a distance of 3 feet or more. Efficacy of this

course is unknown and in many situations not likely (bus, rail, air travel,

grocery shopping) NYC subway averages 4.7 million riders each day.

Los Angeles Metro area averages 1.3 million riders per day.



Travel Restrictions:

The World Health Organization Writing Group stated

“screening and quarantining entering travelers at

international borders did not substantially delay virus

introduction in past pandemics. . . and will likely be even

less effective in the modern era.”

WHO group on SARS concluded that “entry screening of travelers

through health declarations or thermal scanning at international

borders had little documented effect of detecting SARS cases.”

Disease Mitigation Measures Feasibility

Use of masks

– PPE is essential to curtail the transmission of influenza in

hospitals.



– Patients would be advised to wear surgical masks to

decrease respiratory particles being sent into the air.



– In Asia during the SARS epidemic many people wore

surgical masks in public. Studies have shown the ordinary

surgical masks do little to prevent inhaling small droplets

which may contain influenza. The masks can only be worn

for a short time before the pores of the mask clog with

moisture from breathing and the airflow goes around the

mask.

Disease Mitigation Measures Feasibility

Use of Antiviral Medications:

– The effectiveness and optimal use of antivirals is

uncertain due to several factors

Virus mutation, thus increasing the possibility that

resistance can develop

The available quantities of antiviral for prophylaxis

Logisitical challenges with providing timely tx.





The amount of antivirals used to prevent

infection in 1 healthcare worker is the

equivalent of treating 5-7 ill patients

(prophylaxis w/75mg, BID for 8-10 weeks vs. tx

with 150mg, BID for five days)

Disease Mitigation Measures Feasibility

Antivirals (the good news)

GlaxoSmithKline believes it has developed a

vaccine for the H5N1 deadly strain of bird flu

that may b e capable of being mass produced

by 2007.

-The vaccine has proved effective at two doses

of 3.8micrograms during clinical trials in

Belgium.



Sanofi-Aventis drug company is also working

on a vaccine.

Disease Mitigation Measures Feasibility

Use of Isolation:

– With expected shortages of medical beds, home isolation of

non-critically ill influenza patients is a viable option



– There are several logistical issues that may hamper people

from being able to remain isolated in their home such as: the

provision of basic medical care and obtaining food and

supplies.



– “It may not be easy to persuade those without paid sick

leave (some 59 million persons) to absent themselves from

work, unless employers address this problem directly”

Inglesby et. al.

Disease Mitigation Measures Feasibility

Use of Quarantine:



– The aim of voluntary home quarantine is to keep possibly

contagious, but asymptomatic people out of contact with

others. This raises both practical and ethical issues:



Community implementation raises issue of levels of care and support

required

Compliance issues: Will parents be willing to stay home

? What about college issues: dorming

? What about the homeless population (750,000)

What about the economic concerns of individuals, families and the

community.

Ethical issues:

Healthy individuals staying with infected individuals. Quarantine would

prevent healthy children from being sent to stay with other family

members.

Disease Mitigation Measures Feasibility

Large-Scale Quarantine:



– “The World Health Organization (WHO) Writing

Group, after reviewing the literature and considering

contemporary international experience, concluded

that “forced isolation and quarantine are ineffective

and impractical.” Inglesby, Nusso, O’Toole and Henderson



– It is recommended that Large scale quarantine be

eliminated from consideration.

1918 Flu Epidemic Teaching Valuable Lessons

Actions Taken Apparently Were Effective



By David Brown

Washington Post Staff Writer

Wednesday, December 13, 2006; A04





New analysis of how American cities responded to the killer Spanish flu of 1918 suggests that closing schools, banning large

gatherings, staggering work hours and quarantining households of the ill may have saved tens of thousands of lives. Which of

the many non-pharmaceutical interventions was especially effective in reducing mortality is unknown, but all would theoretically

be available should pandemic influenza again sweep the country. The new findings run counter to previous research that

concluded that the public health measures instituted in 1918 may have delayed or dampened the epidemic in many cities but

probably had little effect on the ultimate death toll. The new data were presented this week to Centers for Disease Control and

Prevention experts, who are helping to draw up guidelines for what local health departments might do during the early stage of

an influenza pandemic, when a vaccine would be unavailable and there would be too few antiviral drugs to go around.



"There is reason for optimism. Even almost 100 years ago, with some very simple tools, there may have been an effect of these

measures," said Martin Cetron, a physician who directs global migration and quarantine at the CDC. In 1918, the public health

responses included isolating the ill, quarantining houses, closing schools, canceling worship services, restricting the size of

funerals and weddings, closing saloons and theaters, restricting door-to-door sales, discouraging the use of public

transportation, staggering the hours of business and factory operations, imposing curfews and, in some places, recommending

the use of face masks in public. Howard Markel, a physician and historian at the University of Michigan Medical School, is

leading a project to analyze the experience of 45 American cities, looking for relationships among flu cases, mortality and public

health measures.

The researchers used a model to determine what the epidemic would have looked like had no measures been taken and

compared that result with a city's actual experience.



– St. Louis closed its schools at a time when flu was causing 21 more deaths per 100,000 people per week than what had

been seen in previous years. That step -- the earliest taken by any of 33 cities analyzed so far -- appears to have reduced

St. Louis's flu mortality by 70 percent.

– Cincinnati responded less quickly, invoking public health measures when excess deaths from flu were 46 per 100,000. It

reduced its potential flu mortality by 45 percent.

– Philadelphia was extremely late, not acting until its excess death rate was 250 per 100,000. That reduced mortality by 28

percent, Markel and his colleagues found.





How U.S. communities would react to a sudden closure of schools is uncertain, although the experience this past fall of one

rural Appalachian county suggests that there may be little opposition over the short term. Yancey County, in rural and

mountainous western North Carolina, closed its 2,559-student school system from Nov. 2 to 13 because of an outbreak of

influenza B. A random survey of households found that 91 percent supported the school board's decision. In half of those

households, all the adults worked outside the home. During that period, one-quarter of them had to take time off from work,

mainly because they were ill themselves or had to care for a sick family member, and not simply to stay with children not in

school, said April J. Johnson of the CDC's Epidemic Intelligence Service, who investigated the outbreak. In only two of 220

households did adults have to pay for extra child care when schools were closed. In most cases, relatives and friends stepped in

to help, Johnson found.

Disease Mitigation Measures Feasibility

School Closure:

The impact of school closings on illness rates is mixed.



– Modeling programs suggest that school closures would significantly

decrease disease transmission. However, closing school for longer than

the usual periods would impact working parents as well as have an

adverse impact on the 29.5 million children who are fed through the

National School Lunch Program.



– Additionally if schools are closed so should malls, churches, and other

gathering sites. If all of these sites are closed, how will this effect

internet use? COOP planning?



– Legal issues associate prolonged closing of schools: school board

meeting and the need for a quorum; compensation & work assignment

of school staff; adequate instruction time; school populations with

special needs populations (IEPs); use of the school as a healthcare

facility (ACF); financial and governance concerns (grants); contracts

(performance clauses); and parental communications (advance

notification on prolonged closures). L. Soronen, JD., National School Board

Association.

Containment Units

Biocontainment Patient Care Units (BPCU)

One approach to containing hazardous infectious

disease in hospital settings is a BPCU.



There are 3 BPCUs in existence in the US



Fort Detrick, MD (3 beds)

Emory University Hospital, Atlanta, Georgia (2 beds)

University of Nebraska Medical Center in Omaha, NE

(10 beds)

BPCU

Diseases that could be handled in BPCUs

include:

– Smallpox

– Monkeypox

– SARS

– Avian influenza

– Viral Hemorrhagic Fevers (VHF)

BPCUs

Psychosocial and Ethical Issues

Here are the recommendations made by the

panel of experts:



– Psychosocial issues should be addressed with the

patient on a regular basis

– Counseling support, educ., and discussion with the

family members are important.

– Personal items brought into the unit will have to be

decontaminated or destroyed

– Psychiatrists should be available for diagnosis and

management of patients with more complicated

psychiatric presentations.

BPCUs

Psychosocial and Ethical Issues for Staff

BPCU workers may experience high levels of stress

and thus MH services should be provided.

Staff training is crucial to minimize fears and dispel

misunderstandings.

and speed count in an Emergency.

The message must be repeated, come from a

legitimate source, be specific to the emergency,

and offer a positive course(s) of action.

Risk Communications

To Staff:



It is incumbent upon facilities to develop

and implement effective means to

communicate to their workers information

regarding the outbreak, health risks,

containment strategy, and measures to

protect workers, patients, and visitors.

Psychological Sequale

Traumatic Grief: Child and/or Adult

Acute Stress Disorder

Post traumatic Stress Disorder (9 % in GP)

Depression

Substance Abuse/Substance Withdrawals

Exacerbation of pre-existing conditions

In some cases alteration in Cognitive abilities.

Increased suicide rates

Increase in domestic abuse

Medication issues

Traumatic Grief

Grief is not the same for every person.



Normal grieving usually includes:

Social Withdrawal

Preoccupation

Even painful emotions

With time, the intensity of grief subsides



Traumatic grief is when the emotions remain high and

the individual gets “stuck” somewhere in the grieving

process.

Traumatic Grief – Symptoms

Recurrent intrusive thoughts of the deceased

Intense loneliness for the deceased

Intense sadness, irritability, anger, or bitterness

Persistent feeling of being dazed, or shocked

Avoidance of activities that remind you of the

deceased

Avoidance of social gatherings

Avoidance of places related to the death



Traumatic Grief has sxs of PTSD, anxiety and

depression that persist over time.

Acute Stress Disorder

What is an Acute Stress Response?



ASR is a transient disorder of significant severity which develops in an

individual without any other apparent mental disorder in response to exceptional

physical and/or mental stress and which usually subsides within hours or days. The

stressor may be an overwhelming traumatic experience involving serious threat to the

security or physical integrity of the individual or of a loved person(s). The symptoms

usually appear within minutes of the impact of the stressful stimulus or event, and

disappear within 2-3 days (often within hours). Partial or complete amnesia for the

episode may be present. There must be an immediate and clear temporal connection between the

impact of an exceptional stressor and the onset of symptoms; onset is usually within a few minutes,

if not immediate. In addition, the symptoms:



(a) show a mixed and usually changing picture; in addition to the initial state

of "daze", depression, anxiety, anger, despair, over activity, and withdrawal may all be seen, but no

one type of symptom predominates for long;



(b) resolve rapidly (within a few hours at the most) in those cases where

removal from the stressful environment is possible; in cases where the stress

continues or cannot by its nature be reversed, the symptoms usually begin to

diminish after 24-48 hours and are usually minimal after about 3 days.

Acute Stress Disorder as a Predictor of

Posttraumatic Stress Symptoms

Acute stress symptoms were found to be an

excellent predictor of the subjects' posttraumatic

stress symptoms 7-10 months after the

traumatic event.



High levels of peritraumatic dissociation and

acute stress following violent assault are risk

factors for early PTSD. Identifying acute re-

experiencing can help the clinician identify

subjects at highest risk.

Pre-disaster Factors for PTSD

Gender:

Women or girls were affected more adversely by disasters than were men or boys for

which women's rates often exceeded men's by a ratio of 2:1



Age and Experience :

Middle-aged adults were most adversely affected. Professionalism and training

increase the resilience of recovery workers, although past trauma per se does not.



Culture and Ethnicity:

Majority groups fared better than ethnic minority groups. There are culturally specific

attitudes and beliefs that may prevent individuals from seeking help.



Socioeconomic Status (SES).

Lower SES was consistently associated with greater post-disaster distress. The effect of

SES has been found to grow stronger as the severity of exposure increases.



Family Factors :

Married status was a risk factor for women. Being a parent also added to the stress

of disaster recovery, mothers were especially at risk for substantial distress. Children

were highly sensitive to post-disaster distress and conflict in the family. When measured,

parental psychopathology was typically the best predictor of child psychopathology.

Pre-disaster Functioning and Personality





Pre-disaster symptoms were almost always

among the best predictors (if not the best

predictor) of post-disaster symptoms. Persons

with pre-disaster psychiatric histories were

disproportionately likely to develop disaster-

specific PTSD and to be diagnosed with some

type of post-disaster disorder.

Within-disaster Factors

Bereavement during the disaster,

Injury to oneself or a family member,

Life threat, panic or similar emotions during the disaster,

Horror,

Separation from family (especially among young people)

Extensive loss of property, relocation or displacement.



As the number of these stressors increased, the likelihood

of psychological impairment increased.

Post-disaster Factors

Stability versus change in psychological

symptoms was largely explained by

stability versus change in stress and

resources.



Attention needs to be paid to stress levels

in stricken communities long after the

disaster has passed

Neurological Disorders Associated

With Infectious Diseases &/or

Medications Used in Tx Regiments

Decreased IQ – HIV/AIDS

Cryptococcal Meningitis – HIV/AIDS

Cortical Dementia – HIV/AIDS

Tuberculosis Dementia – excessive

alcohol use, AIDS, TB

Cerebral Toxoplasmosis – AIDS

Herpes Zoster: Shingles

Neurosyphylis: untreated syphilis

Neurological Problems

Pre-Planned Response to Funerals

Lesson Learned



– The family of SARS victims often were unable

to engage in traditional burial rituals.

Mourners had to stand off in a distance.

For some, there was no closure.

Behavioral Practice Guidelines

Do not provide formal interventions

immediately after the traumatic event.

Perform Psychological First Aid (PFA)

Screen for risk factors from those who

seek professional help.

Timely symptom based assessment.

Provide empirically informed interventions.

Attend to traumatic grief.
