Q-Fever Spreads in 2 States

Q Fever spreads into the environment most commonly through livestock infected afterbirth and feces. Q Fever is caused by a microbe and can survive for months even years in dust an soil. People can contract Q Fever by coming into contact with the above mentioned material and inhaling infected barn dust. 

Health and agriculture investigators in Washington have traced the outbreak to a goat herd in the central part of the state where animals on two farms have since been quarantined.

The goats from one of the farms were sold to at least one livestock operator in Montana, where three human cases are confirmed and three more suspected, officials said.               (Yahoo News)

Is there a vaccine for animals & people for Q Fever? 
Yes, but not in USA.

A vaccine for Q fever is not commercially available in the U.S., although a human vaccine (Q-VAX®) is produced and licensed for use in Australia. A similar product, which is not licensed, is administered as an Investigational New Drug in the U.S. This vaccine is available through the U.S. Army Medical Research Institute of Infectious Diseases for vaccinating at-risk persons. A vaccine for use in animals has also been developed, but it is not available in the U.S.     Q Fever-U.S. Army Center for Health Promotion and Preventive Medicine     

There is currently not a licensed vaccine to prevent Q fever in livestock in the United States.  Colorado State University            "Q Fever" by Dr. Van Meter

Why do I bring this up? Q Fever can be contracted by humans from livestock, yet there is no livestock vaccine. In 2008 the number of yearly cases of Q Fever went down dramatically with less than 140 human contractions.

Whereas with brucellosis there is an effective vaccine (if ranchers choose to use it) and states like Montana have funding appropriated by the legislature on developing even better vaccines.  The number of human contractions of brucellosis in the USA is 100-200 per year.

Yet, even with all this funding and prevention federal tax payer money is used each year to harass and slaughter Yellowstone National Park Bison with the excuse that these bison transmit brucellosis to cattle, even though there has never been a case of this happening. No cattle are allowed on the bison birthing grounds or even into the state of MT until mid June, long after bison have given birth.
