A new coalition wants to set up an
early warning system for diseases
that pass between animals and humans.
Samara Freemark reports
some research institutions and conservation
groups are launching the PREDICT program:

Organizers hope the program will help prevent the spread of diseases like avian flu, ebola, and swine flu. PREDICT researchers will work in disease ‘hotspots’ overseas.

Program director Stephen Morse is an epidemiologist at Columbia University in New York. He says the program will identify new viruses in animals before they spread to humans.

“We don’t even know how may emerging viruses, let alone other infectious organisms there are out there in nature, but the number must be large.”

The PREDICT program will also create better global disease warning systems.

“This is really essential to our survival as well as something very important to understand if we want to be able to control infections in the future.”

Morse hopes the program will help governments stop local outbreaks before they become global pandemics.

A Treatment for Bleeding Fish Disease?

A common treatment in fish hatcheries may slow – or even stop –

the spread of an invasive virus that’s killing fish across the Great Lakes.

Jonathan Brown has more:

It’s called Viral Hemorrhagic Septicemia. Humans can’t catch it, but it
causes internal bleeding in fish.

The virus is hurting the region’s multi-billion-dollar sport fishing industry.

Now, researchers are finding that adding iodine – a common practice in fish
hatcheries – could prevent the virus from spreading.

Steve LePan is a biologist for the state of New York. He says a study at
Cornell University found Walleye eggs treated with an iodine solution were
not infected with VHS.

“We can’t say for sure that it’s exclusively the iodine that kills it. There may
be other things we do to the eggs that also affect the virus, as well.”

Those ‘other’ treatments include bathing Walleye eggs in Tannic Acid for a
few minutes before incubation.

LePan says there’s still a lot to learn about VHS, but he’s cautiously
optimistic that hatcheries can breed fish uninfected by the disease.

Fish Disease Spreads to New Waters

Despite efforts to stop it, there’s a new
indication a nasty fish virus is spreading. Christina
Shockley has the latest:

The name even sounds scary: viral hemorrhagic septicemia. It causes fish to bleed to
death.

VHS has been in the Great Lakes for at least three years. Officials have been trying
to confine it to the Great Lakes basin, but now it’s spread into central Ohio.

Elmer Heyob is with the Ohio Department of Natural Resources.

He says the worst-case scenario is that VHS could get into a hatchery that stocks fish
for lakes and streams, and that cloud hurt the region’s economy.

“First the hatcheries, then the fishery, then the people that support the fishery, the
boating industry, it just goes on and on.”

Heyob says to stop VHS from spreading, you shouldn’t move fish from one lake to
another, and you should clean boating and fishing equipment before you move to a
different lake.

Researchers believe eventually fish build up immunity to the disease.

VHS does not pose a threat to people.

Respiratory Rankings Wrong?

A recent ranking of the worst U.S. cities for respiratory infections is being called into question. The GLRC’s Erin Toner reports:

A recent ranking of the worst U.S. cities for respiratory infections is
being called into question. The GLRC’s Erin Toner reports:


The list was compiled by BestPlaces.net, and funded by the
pharmaceutical company Sanofi-Aventis. It was based on the prevalence
of respiratory infections, prescriptions, and the rates of antibiotic
resistance. But one physician says the methodology might not give an accurate
picture.


Doctor Randolph Lipchik teaches at Medical College of Wisconsin. He
says the data is likely being skewed by the antibiotic resistance factor.


“Most respiratory tract infections, whether it’s sore throat, or an ear
infection or bronchitis, is viral, and antibiotics don’t treat that, and
antibiotics don’t prevent spread of those infections.”


Lipchik says it might be that hospitals in cities high on the list have a
high amount of resistant bacteria, making it look like they have more
trouble with infections than cities ranked better by Bestplaces.net.
