What is Hantavirus?
• Hantavirus is (according to: Microbiology with diseases
by Body System written by: Robert Bauman) a group
of bunyaviruses that are transmitted to humans by
inhalation of virions in dried deer-mouse excreta and
causes Hantavirus pulmonary syndrome.
Hantavirus Pulmonary syndrome or HPS: Is a
rapid, severe, and often fatal pneumonia
caused by infection with a Hantavirus.
What is Hantavirus? (Con’t)
The Severity of Hantavirus
• Deer mouse
• White footed mouse
• Rice rat
• Cotton rat
• Not all rats carry the virus, but to be safe
avoid all wild mice and rats.

• By breathing in the virus, this happens when
the mouse/rat urine and droppings that
contain the virus are stirred in the air.
• People can also become infected directly by
touching the feces, urine, or nesting area
that are contaminated with the virus, and
get it on their hands and touching the
extremities of one’s own eyes, nose, and
mouth.
How People get Infected
• The infected fell sick 1 to 5 weeks according to the
CDC.
• The symptoms:
• Fever
• Severe muscle aches
• Fatigue
The Side Effects
People have a hard time breathing.
The severity increases to:
• Headaches
• Dizziness
• Chills
• Nausea
• Vomiting
• Diarrhea
• Stomach pain

The Yosemite Hantavirus outbreak is unique compared to other cases.
This outbreak has killed in clusters instead of individual cases as usual. http://www.businessinsider.com/yosemites-hantavirus-outbreak-kills-a-third-camper-2012-9
For an outbreak like Yosemite's, the conditions need to be "a perfect storm" of a wet, warm spring followed by a hot, dry summer, Higa said.
The mild spring allows for an abundance in the deer mouse food supply. This leads to increased breeding. The behavior of the mice becomes more aggressive in competition for mates and manifests as biting. From what researchers understand, deer mice spread hantavirus among their populations by biting each other, Higa said. The rodent hosts carry the virus the rest of their lives but are not made ill by it.

Why it Has Gained National Attention

The original test was deemed a false positive.
After more tests were done Hantavirus was
ruled out.
“Health officials said disrupting the old, dusty
mounds of clutter inside the home could have
easily released the virus.”
What the women is still ill with is yet to be
determined.

Additional Information
• “One theory is that tourists and all their food are feeding a population boom of infected mice.”
• After 20 years in the U.S. there is still no cure.
• “(CBS News) YOSEMITE NATIONAL PARK, Calif. - There has been an outbreak of hantavirus, a deadly disease spread by rodents. More than 22,000 people who visited Yosemite National Park since June have now been warned they should get tested. There have been eight confirmed cases and three people have died.”
• “One case of hantavirus is rare; eight cases in one location is unprecedented.”http://www.cbsnews.com/8301-18563_162-57510794/yosemite-park-reacts-to-hantavirus-cases/
What Researchers Are Doing
“Researchers found the source. Knowing rodents carried
hantavirus, they trapped hundreds of small mammals and
found the virus in nearly one-third of the deer
mice, according to the CDC. Before year's end, scientists
isolated the specific type of hantavirus that caused the Four
Corners cases and grew it in a laboratory.”
The CDC took tissue samples from the survivors of the virus
and the those who died, scientists then tested for antibodies
against viruses. Which in the end they found a match.
