OBJECTIVES
 Understand the possible mechanisms of
transmission, pathophysiology, signs & symptoms
and treatment for Middle East Respiratory Syndrome
 Describe precautions that need to occur for pre hospital & hospital providers
MERS-nCoV: Mechanism of Transmission
 Identified in September
2012
 Similar to coronaviruses
found in bats
 Isolated in camels in
Qatar, Egypt and Saudi
Arabia-unknown if camels
are the source of the
virus
 Human to human
infection in health care
workers noted
 Lab test for active
infection and antibody
test for previous infection
MERS-nCoV Transmission
 Transmitted through the air
through droplets from coughing
or sneezing
 Transmitted through close
personal contact: touching or
shaking hands
 Spread by touching
contaminated objects or
sur faces and then touching
your eyes, nose, or mouth
 Transmitted in the Middle East
by the same mechanisms when
in close contact with
dromedar y camels used for
racing, transpor tation, food,
and as pets.
 Virus found in camel feces &
urine, unpasteurized camel
milk & cheese, and in camel

Middle East Respiratory Syndrome
 Middle East Respiratory Syndrome (MERS -nCoV
is caused by a novel beta coronavirus that
usually causes a severe respiratory illness
which has resulted in deaths in ~ 30% of
individuals with confirmed infections. It is
called a coronal virus because it appears to be
surrounded by a crown.
History & Symptoms of MERS-nCoV
 Histor y of travel to Middle
Eastern Countries where MERS nCoV is prevalent
 Upper Respirator y Symptoms
Fever
Cough
Shortness of breath
Hypoxemia
Pneumonia
 Gastrointestinal Symptoms
Nausea
Vomiting
Diarrhea
 Kidney Failure
Treatment
Supportive Care
No vaccine to date
Researchers have
found that
monoclonal
antibodies - MERS-4
and MERS-27, have
strong neutralizing
activity against
MERS-CoV.
Prevention While in Flying
 Wash hands often
 Avoid touching your face
 Avoid close contact with sick people
 Don’t share cups or eating utensils.
 Clean and disinfect surfaces like door handles, toys,
tray tops, etc.
 Practice the "Canadian salute" of coughing and
sneezing into your elbow.
Prevention in Middle East
 MERS-CoV can survive for a long time in milk and suggested
that consumption of unpasteruized milk, common on the
Arabian Peninsula, could be a source of infection.
Pasteurization kills the virus.
 Don’t drink unpasteurized milk or eat unpasteurized cheese.
 Camel meat should be thoroughly cooked, not eaten raw
 Don’t drink camel urine (Believed to have medicinal benefits)
 What should be done about camel feces dried for fuel?
New Prevention Guidelines Qatar June
2014
Qatari has put into
effect standards for
protection of camel
workers.
 Frequent hand washing
 Use of protective
facemasks—although
temperatures of up to
50°C make this almost
impossible
 Use of protective
clothing and gloves
Prevention of Transmission to Healthcare
Providers
 Airborne Infection Isolation Room (AIIR)
 Limit the number of healthcare providers present during the
aerosol-generating procedures (ETT placement) to only those
essential for patient care and support.
 Conduct the procedures in a private room and ideally in an
AIIR Gloves
 Gowns
 Eye protection (goggles or face shield)
 Respiratory protection that is at least as protective as a fit tested NIOSH-certified disposable N 95 filtering face piece
respirator.
 If a respirator is unavailable, a facemask should be worn. In
this situation respirators should be made available as quickly
as possible
 Monitor healthcare providers for 14 days after the last known
Do Not Eat Anything You Cannot
Positively ID
“ Ever y
mushroom is edible, but
some only once."
 Galerina autumnalis
 Brown cap, small fragile ring on
the stem. The lower part of the
stem is usually darker brown,
sometimes with little tufts of
hyphae. Above the ring the stem is
usually lighter tan in color and
lacks ornamentation. The gills are
~ the same color as the top of the
stem and darken with age. The
mushrooms are only about 2-5 cm
in diameter and the stems are
usually less than 2 inches (5 cm).
The spore print is a rusty brown.
False Chanterelle
 False Chanterelle, is an
orange funnel-shaped
mushroom which has
been confused at times
with the true chanterelle
 Orange cap up to 8 cm
across, initially convex but
becoming funnel-shaped.
The decurrent gill-like
structures are orange, riblike folds and forked. The
orange stem is ~ 5 cm
high and lacks a ring
 The spore print is white.
Chanterelle Look-a-like Mushrooms
 Jack O'lanterns grow in
large groups with the
stems attached.
Chanterelles are usually
solitary or in a small
bunch with separate
stems.
 Jack o'lanterns are
more orange, less
yellow.
 Chanterelles will always
be near trees due as
they are mycorrhizal
False Chanterelle “Poisoning” Symptoms
 Tom Volk, a leader in mycology from the University of
Wisconsin, describes the False Chanterelle or Jack -o-lantern
mushroom poisoning as, " Omphalotus olearius won't kill you it will just make you wish you were dead." Due to vomiting
and diarrhea for several days after ingestion.

ingestion, and last for several hours.
Symptoms of Isoxazole Derivatives
Poisoning
 Nausea and vomiting are
quite common,
 Central nervous system
effects: confusion, visual
distortion, a feeling of
greater strength, delusions,
convulsions, drowsiness, fall
asleep and can not be
roused. In rare cases the
coma-like state can last for
more than 24 hours.
 No deaths in 100 years
 Spontaneously awaken
Case Presentation
 A 24 y/o calls 911 with complaints of abdominal pain and
sweating. On arrival to the scene or on arrival to your ED you
find the patient to be diaphoretic, with drenching sweats,
copious salivation and lacrimation, as well as crampy
abdominal pain. He vomits twice and has another episode of
diarrhea. Otherwise, his vital signs were stable. His pupils
were measured at 3 mm bilaterally and were reactive to light.
On auscultation of the lungs, there were coarse crackles up to
the mid lung bilaterally.
 What is your differential diagnosis?
 A 32 y/o family member calls 911 after having episodes of
crampy abdominal pain with diarrhea and vomiting as well as
blurred vision 2 h after consuming the mushrooms. She also
had profuse sweating, lacrimation, and coarse crackles

verna, A . bisporigera, Conocybe filaris, Galerina
autumnalis, G. marginata, G. venenata, Lepiotia
castanea, L. helveola, L. josserandii & close
relatives.
 Account for 90 percent of all poisonous
mushroom cases.
 Amanitas have a bulbous base
 Death Cap
 Caps are generally greenish in color, with a white stem
and gills.
 The Death Destroying Angel smells sickly sweet
 White stalk and gills
 Bulbous base
 The cap can be pure white, or white at the edge and
yellowish, pinkish, or tan at the center.
 Has a partial veil, or ring (annulus) circling the upper
stalk, and the gills are "free," not attached to the
stalk.
 The most telltale of the features is the presence of a
Mechanism and Symptoms of Amanitas
Poisoning
 a-amanitin slowly attacks the
enzyme RNA polymerase in all
body cells, par ticularly the
liver. Ultimately af fects the
central ner vous system and
kidneys.
 As little as 1/3 of the cap may
be eaten resulting in death
Stages & Symptoms of Amanita
Poisoning
 First stage is a latency period of 5 to 24 hours after ingestion,
in which the toxins are actively destroying the victim's kidneys
and liver, but the victim experiences no discomfort. There may
be a feeling of unease
 Second stage is a period of about 24 hours characterized by
violent vomiting, bloody diarrhea (cholera -like), and severe
abdominal cramps.
 Third stage is a period of 24 hours during which the victim
appears to recover (if hospitalized, the patient is sometimes
released!)
 Fourth stage is a relapse, during which kidney and liver failure
often occurs, leading to death. There may be more than one
relapse.

Prevention of Mushroom Poisoning
 Only eat mushrooms you have positively identified yourself.
 Identify mushrooms a second time during preparation and
cook them properly, unless you know that the species can be
eaten raw.
 Do not combine mushroom types.
 Retain a sample of any mushroom you are not well experienced with for analysis in case of poisoning.
 Inform yourself about deadly mushrooms that are look -alikes
of edible ones. "Deadly twins" dif fer regionally, so take into
account regional variation.
 Do not gather mushrooms that are dif ficult to identify, unless
you have expert knowledge.
 Consume only a small amount the first time
Mushroom Safety Tips
 Be cautious with white-capped mushrooms or mushrooms with
white gills; this eliminates many hard -to-identify species,
including several deadly species.
 Do not eat wrinkled, brain -like, or saddle-shaped mushrooms.
 Beware of any mushroom with a ring on its stalk or any
mushroom that grows out of a cup or has an enlarged base.
 Avoid LBM's. Species of Little Brown Mushrooms can rarely be
determined by non-professionals.
 Avoid Boletes which have red pore mouths or which bruise
blue or taste bitter.
 Do not eat any puf fball that is not pure white and uniform in
texture inside.
 Keep each species that you collect in a separate container.
 Be aware that some mushrooms cause reactions when
consumed with alcohol.
Wisconsin Creates New Crossbow Season
“With the official signature of Governor Scott
Walker the dawn of a new age is finally upon
Wisconsin hunters. Once only legal for
hunters age 65 or older, or those with physical
disabilities preventing them from using a
compound or traditional bow, crossbows will
now be legal for hunters of all ages
throughout the state's archery deer hunting
season.”
Longbows, Crossbows, Composite Bows &
Arrow Injuries
 A Wisconsin man was injured
when fired the crossbow and
stuck his thumb in the path of
the bow string. In so doing, he
severed par t of his thumb.
EMS and fir st responders had a
dif ficult time locating the
amputated par t, which could
not be attached.
 Injur y prevention education –
Teach user s to, “Never allow
your fore-grip hand’s finger s or
thumb to move above the
barrel’s flight deck or into the
bow string or cables’ release
path.”
Types of Bows
Crossbow Injury
Case
 A 16-year-old boy sustained a penetrating injury to
his left wrist and hand from a broken arrow shaft.
This occurred when a hollow carbon fiber arrow
broke while he was attempting to shoot it from a
compound bow. The shaft of the arrow, broken at its
mid portion, entered the left wrist
Arrow Injuries
Treatment of Patient with Arrow
Impalement
 Xray
 CT scan to map the
track
 Surgical Removal
Pre-hospital & Emergency Treatment of Arrow
Impalement
1 . Stabilize the arrow/treat as an impaled object by applying
adhesive tape or another stabilizer to the base of the shaft.
2. Wrap a clean towel or gauze around the base of the shaft,
and then apply direct pressure on the bleeding wound.
3. Assess for and treat airway, breathing issues and shock
4. Avoid moving or bumping the arrow during transport.
5. Provide a duplicate arrow if possible to healthcare providers.
A duplicate arrow will help medical professionals determine
the size and shape of the arrow and know if they have
retrieved all the pieces of the arrow from the victim.
Pro’s and Con’s of Crossbow Hunting
 Pro’s - Crossbows allow hunters to get out in the woods
more often, and allow them to be more successful
hunters.
 Pro’s - Crossbow hunting has increased hunting license
revenue and has increased the number of bow hunters.
 Pro’s – Crossbows provide an effective game control
management tool.
 Con’s – Increased harvest of deer will decrease the
numbers available for gun season.
 Con’s – Bow Season may need to be shortened in the
future due to increases in harvest affecting long bow
hunters.
 Con’s – Rifle hunters will move to crossbows shifting

 Two men were injured when their truck rolled over on Highway
41/45 on Wednesday morning and landed in a flooded ditch,
the Germantown fire chief said.
 "They were very lucky it didn't end up upside down because
they could have drowned," Fire Chief Gary Weiss said.

Firefighters had to deal with chest-high water
in the ditch from heavy rainfall and crossed
the ditch by laying ladders across the water to
the truck.
Flash Flooding in Wisconsin
 LAKE DELTON, Wis. — Flash
floods inundated a southwest
Wisconsin town Monday for the
second time in 10 months,
while 60 miles away an
embankment along a man made lake gave way,
unleashing a power ful current
that ripped homes of f their
foundations.
 The swollen Kickapoo River
engulfed nearly the entire
village of Gays Mills, WI,
forcing about 150 people to
evacuate. The town was
reduced to a grid of canals
with cars submerged up to
their windows and parking lots

Flash Flood Statistics
 Thousands of Wisconsinites live along
rivers that are periodically swollen
from melting snow or rains associated
with thunderstorms
 Flash flooding is the Number One killer
during thunderstorms
 One of the most common and
widespread of all natural disasters
 84 Americans died from floods in 2013
 Six inches of fast moving water can
move a vehicle & knock over an adult
 Two feet of water is enough to make
most cars float
 At least a couple people in Wisconsin
had to be saved from raging waters in
April 2014
Flooding in McFarland, WI
Flash Floods - Floods That Happen in a
Flash!
 Flash floods generally develop within 6
hours of the immediate cause .
 A rapid rise of water over low -lying
areas.
 Flooding may occur well away from
where heavy rain initially fell . (This is
especially common in the western
United States where low lying areas
may be very dry one minute, and filled
with rushing water from upstream the
next)
 Rainfall from slow -moving or multiple
thunderstorms over the same area,
rapidly changing the water levels in
stream or creeks and can turn small
waterways into violent, raging rivers
 Urban areas are especially prone to
flash floods due to the large amounts
of concrete and asphalt surfaces that
do not allow water to penetrate into
Causes & Effects of Flash Floods
 Heavy rains falling over a short period of time (a few hours or less)
 Ice jams or debris jams on rivers
 Dam or levee breaks. The sudden buildup of water can cause a
large crest of water to move quickly downstream, wiping out
most everything in its path.
 Capable of rolling boulders, tearing out trees and destroying
buildings quickly with little or no warning
 Can cause mudslides. June 2013 a mudslide from a flash flood &
debris left on Highway 78 outside of Mazomanie resulted in rerouting
traffic
Flash Floods from Rainfall & Snow Melt
Wisconsin Flash Floods
 1 884 Eau Claire – A 27-foot flood carried away houses and all the
bridges in Eau Claire, WI
 1911 Spar ta - Heavy rains filled the upstream tributaries to the
Black River, two dams above Black River Falls gave way. The river
rose 20 feet over its already high level and rushed through city all
day. 80 buildings and 42 acres of land, including entire hillside
neighborhoods, were swept away
 1943 Black River Falls - Bear Creek jumped its banks af ter
torrential rains. Homes and businesses were inundated 3-4 feet
deep, bridges were washed out, and roads destroyed. In addition,
water mains broke, which not only reduced the water supply but
contaminated water still available. At least one person drowned
 1993 Statewide Flooding in WI – Snowy winter, 2-3 times normal
rainfall in Upper Mississippi Valley. Thunder storms with 2 to 7
inches of additional rain on June 17-1 8 resulted in ever y major river
in Wisconsin flooding; 20 dams were over topped, broken, or washed
away.
 2008 Southern Wisconsin – Seven southern counties received more
than a foot of rainfall in June. The town of Ontario received more
the 6 inches on June 8, and Baraboo more than 17 inches during
the month. Lake Delton, in the Wisconsin Dells, breached its dam
and emptied into the nearby Wisconsin River on the 9th

Stationary objects
Holes, manholes
Entanglement or injury from hidden obstructions above and below the water
Drowning
Swift Water Characteristics
 Eddies - Upstream water flows around obstructions in the
current leaving a void on the downstream side of the
obstruction, causing the downstream to flow upstream to fill
in the void behind the obstruction.
 Upstream V's – Caused by water striking an object and water
going around it. An area that may be trapping a subject
against an obstacle.
 Downstream V's - Caused by water moving around several
obstacles coming together in the path of least resistance.
These Downstream V's will contain some of the fastest moving
water in the channel. If the subject does not become trapped,
the downstream V's have the highest probability of containing
the subject.
 Pillows are also indicators of a submerged or partially
submerged obstacle. The pillow will lie upstream if the
obstacle is completely below the surface & downstream if the

Water-Rescue Principles
 Reach – Throw - Row – Go
 Reach using long, handled tools, such as pike poles, to try to reach
victims.
 Throw ropes with life rings or other floating devices victims. Air -filled
objects, such as footballs or soccer balls, can be thrown to victims so
they have something to hold onto while in the water.
 Push, motor or row boats to victims if necessary.
 Row - Boats can be extremely dangerous in fast water rescues.
Propellers on outboard motors can become entangled in branches,
vines or other debris or even in fences in higher floodwaters
 Go - Rescuers entering the water, need PPE floatation gear, head and
foot protection, survival or flotation suits. Boots are tied tightly to
reduce the amount of water, hydrocarbons, chemicals or other
hazards that can get in.
Tie off rescuers so they can be retrieved quickly. They need to carry a
knife to cut the rope if they become entangled

Active Core Rewarming
Core Temperature Afterdrop
 Core temperature continues to fall after
rewarming is instituted
 Simple temperature equilibration
 Restoration of peripheral circulation sets up
a countercurrent flow with cold, acidotic
blood shunted to the core
Treatment
 Hypothermia can be rewarmed passively if
mild (> 32 o C) and the patient is stable
 Unstable and temp < 32 o C - aggressive active
core rewarming & partial cardiac bypass if
condition deteriorates
 Cardiac instability and risk of V-fib begins <
30 o C
 Vital signs are difficult to assess at
temperatures < 30 o C
 Do not begin CPR if organized rhythm is
present and temp is < 30 o C

Prevention of Injury During Flash Floods
 Avoid flooded bridges
 Never drive through flooded roadways. Turn around, don't drown.
 Be especially cautious at night when it is harder to recognize flood
dangers.
 When a flash flood is headed your way, you may only have seconds
to save your life.
 Abandon all per sonal proper ty and flee to higher ground if a flash
flood is approaching. Any delay, even for a second, could be the
