“It never went away.”
The virus has not changed to become more
deadly.
Drug-resistant strands emerging.
Child deaths--had at least one severe
underlying illness or underlying disability,
actually, rather than illness, in most of the
cases -- cerebral palsy, muscular
dystrophy, long-standing respiratory or
cardiac problems.

CDC-September 15, 2009
Child deaths--had at least one severe
underlying illness or disability-cerebral palsy, muscular dystrophy,
long-standing respiratory or cardiac
problems.
 Children who didn't have an
underlying condition and who did
become severely ill, and they were
generally infected also by bacteria.


CDC-September 15, 2009
Most people recover from infection
without the need for hospitalization or
medical care.
 Causes more serious lung disease
than seasonal flu strains and sheds
from the lung and throat tissue where
it reproduces at higher rates.**
 High fever post viral infection??
Suspect bacterial pneumonia.

Current Status
Twenty-one states are reporting
widespread influenza activity at this
time.
 Reports of widespread influenza
activity in September are very
unusual.
 Almost all of the influenza viruses
identified so far are 2009 H1N1
influenza A viruses.

H1N1 in Schools



9/23/2009
Some schools in Florida
and Canada have banned
hand sanitizers because of
the high concentration of
alcohol.
Officials worried about
flammability and potential
misuse as an intoxicant.
Must store larger pump
containers and extra
bottles in fireproof
cabinets or outdoor sheds.

New Thinking on School
Closures
“The potential benefits of preemptively
dismissing students from school are often
outweighed by negative consequences,
including students being left home alone,
health workers missing shifts when they
must stay home with their children,
students missing meals, and interruption of
students’ education.”

Masks and Respirators
Estimated Need
 More than 30 billion
masks needed in a
pandemic


27B surgical masks
5 billion N-95
9/23/2009
US Stockpile
 SNS contains 119 million
masks


39 million surgical
80 million N-95’s
14
Reality

9/23/2009
One anecdotal report— 7000 masks
in caring for ONE H1N1 Influenza A
patient in one ICU
15
N-95 vs Surgical Mask?
CDC – “We want to ensure that
health care workers are safe.”
 Revised guidance expected this week


IOM Advisory CommitteeN95

9/23/2009
The committee was
not charged with
considering
implementation issues,
which include cost,
availability of
equipment, and other
considerations (such
as effective vaccines)
in the implementation
of such guidance.
17
IOM Advisory CommitteeN95
An emphasis is needed on
implementing a range of strategies
across all levels.
 Studies on influenza transmission
show that airborne transmission is
one of the potential routes of
transmission.

9/23/2009
18
IOM Advisory CommitteeN95


9/23/2009
The committee endorses the current CDC
guidelines and recommends that these
guidelines should be continued until or
unless further evidence can be provided to
the effect that other forms of protection or
other guidelines are equally or more
effective.
Employers should ensure that the use and fit
testing of N95 respirators be conducted in
accordance with OSHA regulations…
19
Key Points-IOM

9/23/2009
The use of respirators should be for
those in initial contact with individuals
presenting with unidentified febrile
respiratory illnesses and those
healthcare workers in close contact
with individuals with confirmed or
suspected H1N1.
20
Key Points-IOM

9/23/2009
PPE needs to be viewed as one part
of a continuum of controls to ensure
worker and patient safety that range
from engineering controls and
administrative approaches to
pharmaceutical measures.
21
Key Points-IOM
Emergency medical responders
 Fit-tested disposable N-95 respirator
if in close contact

Aerosol generating activities
 Interfacility transfers


This Just In…


Last week, American Society for Microbiology
Meeting describes first randomized controlled trial
comparing N95 to facemasks
MacIntyre Study found that surgical masks had no
protective effect. In contrast, the N95s, compared
with the controls, were linked with




9/23/2009
60%
75%
56%
75%
reduction in risk for any respiratory illness
reduction in flu-like illness
decrease in lab-confirmed respiratory illness
reduction in confirmed flu
23
Really???

The researchers found that fit-testing of
the made no difference in protection.

Influenza and GBS
Influenza virus infection has also
been associated with GBS.
 Baseline rates of GBS and
miscarriages (1 per 100,000 pop.)
 In 1976, there was a small risk of
GBS following influenza (swine flu)
vaccination (approximately 1 per
100,000 persons vaccinated).

9/23/2009
33
Influenza and GBS
Numerous studies have been done to
evaluate if other flu vaccines were
associated with GBS. In most
studies, no association was found.
 Two studies suggested that
approximately 1 person out of 1
million vaccinated persons may be at
risk of GBS associated with seasonal
influenza vaccine.


August 2009-”Extraordinary surges”
 Hospitals can establish alternative
screening sites ON CAMPUS to
perform MSE’s for persons presenting
to the ED with ILI.
 Can be redirected after qualified
person determines there is no
obvious EMC.

9/23/2009
38
EMTALA and Pan Flu
Off-site ILI screening centers
 Can’t refer patients there from ED.
 Can’t be used to screen patients for
other urgent, unscheduled illnesses or
conditions.

Influenza in Context



9/23/2009
Seasonal influenza results in 200,000
hospitalizations annually in the United
States.
Seasonal influenza causes 36,000
thousand deaths each year in the US,
ranking it among the nation’s top 10
causes of death.
Influenza related deaths are usually due
to secondary pneumonias, exacerbated
cardiopulmonary conditions, or other
chronic diseases.
41
Critical Strategies

Respiratory Hygiene





9/23/2009
Cover your mouth
when you sneeze or
cough
WASH YOUR HANDS
FREQUENTLY
Avoid touching your
face, eyes, nose, mouth
If you are sick, STAY
HOME
Immediately discard
used tissues and then
WASH YOUR HANDS!
42
Current Recommendation

9/23/2009
Stay home if you are sick for 7
days after your symptoms begin
or until you have been symptomfree for 24 hours, whichever is
longer.
43
Fall 2009 so far…


The epidemiology of the
disease caused by the 2009
H1N1 influenza virus in the
Southern Hemisphere is very
similar to that described in the
United States this past spring.
There have been no
significant changes detected
in the 2009 H1N1 influenza
virus isolated from persons in
the Southern Hemisphere as
compared to viruses isolated
from persons in the Northern
Hemisphere.
