Scientists are comparing the effects West Nile Virus to Polio because they share
similar
symptoms. The Great Lakes Radio Consortium’s Jenny Lawton has more:
Researchers say both the West Nile virus and Polio can live in the body for years
before
launching an attack against the nervous system. And there’s evidence both can lead
to other
medical problems years after the initial illness.
In the case of polio, this delay is known as “PPS,” or “post polio syndrome.”
Science journalist, Janet Ginsburg, says those kinds of outbreaks begin with a range
of symptoms.
“And a lot of people had a flu-like illness, just like West Nile fever. These
people today are
showing up with PPS. So you have this model of polio.”
Ginsberg says more research needs to be done before a connection is certain.
There have been fewer than a couple of dozen cases of the West Nile virus in the
Great Lakes
States so far this year.

The EPA wants communities to do more to protect
drinking water from a harmful microorganism. That could mean
several changes for cities around the Great Lakes. The Great
Lakes Radio Consortium’s Chuck Quirmbach reports:
Ten years ago, a Cryptosporidium outbreak in Milwaukee led to
the deaths of more than 100 people who had weakened immune
systems. The outbreak sickened 400,000 other people.
Since that time, Milwaukee has made 100 million dollars in water treatment plant
improvements. Milwaukee waterworks superintendent Carrie Lewis
says the EPA’s plan to make all drinking water treatment
systems monitor and guard against the microbe means some
cities face new construction at their water treatment buildings.
“Because one doesn’t easily add more barriers to
organisms like Cryptosporidium without adding more physical plant
to the water treatment plants.”
Lewis expects some cities to debate the cost and benefits of the
rule package.
For the Great Lakes Radio Consortium, this is Chuck
Quirmbach reporting.

Public health officials in the Midwest are trying to control a virus outbreak…
believed to be linked to infected prairie dogs sold as pets. The Great Lakes Radio
Consortium’s Sean Crawford reports:
There are several confirmed cases of monkeypox now and more are expected.
Authorities are working to track down more than 100 customers of a
suburban Chicago exotic pet dealer.
Dr. Craig Conover with the Illinois Public Health Agency says those who purchased
prairie dogs during the past two months might be at risk.
“We’re making every effort to contact them personally. Many of the individuals are out
of state so the names of such individuals have been transmitted to other state health
departments.”
Conover says some prairie dogs later were traded at swap meets… making it more
difficult to locate them. This is the first time monkeypox has shown up in the
Western hemisphere. While similar to smallpox, it’s usually not as serious, but can
result in fever, chills, and rashes.

Every year, tens of thousands of avid birdwatchers wander through
frozen fields and marshy swamps. Their job is to record as many birds
as they can find in a given area. For birders, it’s a day to enjoy the outdoors
while doing what they love most. But as the Great Lakes Radio Consortium’s
Karen Kelly reports, that passion serves another purpose – it helps scientists:
(sound of footsteps)
Georgina Doe: “There’s five robins right there and there’s three common mergansers,
males…”
Georgina Doe scans the shoreline with her binoculars. Within seconds,
she spots a tiny glimpse of a bird and names it.
She knows them by the way they dive in the air, and the way they thrust
their chests out.
Doe has been scanning the treetops of Carleton Place, Ontario for
more than 30 years. She says she loves the chase and the element of surprise.
And over the years, birding has also been her escape.
She remembers watching a robin build its nest when her grandson
was seriously ill.
“So I used to count the birds every morning before I went off to
the hospital. And then after that, you come back to reality. Somehow a
little bird can just make you feel better.”
Birds have been a part of all of our lives. We might not know their names.
But we can remember holding a baby chick. Or hearing a cardinal on a crisp cold day.
But now, many bird species are dwindling. And scientists are
counting on birders like Georgina Doe to help them find out why.
Doe is one of many birders in North America who collects
information for scientists. Jeff Wells works with that information
at Cornell University’s Lab of Ornithology.
“There’s no way that we could ever pay the tens of thousands of
trained biologists that would be necessary to gather this kind of
information. It’s only possible when we can engage volunteers like
we do in citizen science projects.”
Cornell runs at least a dozen programs that rely on information
from average birders.
There’s the Christmas Bird Count. About 50 thousand people participate.
Another 50 thousand track species during the Great Backyard Bird
Count in February.
The volunteers reported that wood thrushes are disappearing in
many areas. And they’re tracking the effect of the West Nile Virus
on bird populations.
“If a little bird dies, usually it just disappears quickly
and no one ever sees it. So we don’t really know the impact.
And so looking at the differences in the numbers and distribution
might give us some sense of when the disease was rampant in the summer,
whether it killed off enough birds to make a noticeable
difference in our count.”
(sound of quiet footsteps)
Robert Cermak: “You can see it’s about 10 inches high. It’s all fluffed
up right now so it’s
hard to get a sense of
its mass…”
Birder Robert Cermak tiptoes closer to a barred owl sitting in the
crook of a tree.
We’re in Ottawa, Canada’s capital and a city of about a million
people. When it comes to bird counts, this is Cermak’s territory.
“It’s not often that you actually see a barred owl, any owl, during
the day. They’re usually more secretive. This one is not too
afraid to be out so it’s probably become more accustomed to having people
around it, since this is the center of the city.”
Like Georgina Doe, Cermak has been birding for years. But even with
veterans, there’s always concern about their accuracy. Cermak
discovered this firsthand when he reported seeing a rare
harlequin duck last year.
“I sent it in and a few hours later, someone from Cornell –
very politely because it’s a delicate subject to question
someone’s sighting of a rare bird – but they very delicately
indicated that a harlequin duck is extremely unusual in Ontario and
could I please provide a few extra details.”
Cermak sent them a published account of the sighting. He also
gave them the number of a local expert.
Jeff Wells says researchers check their facts carefully. They look
for reports that don’t match others in the surrounding area. Sometimes
an investigation turns up a trained ornithologist… and sometimes not.
But overall, Wells says the information has formed the basis for
hundreds of published studies.
That’s something that makes birders like Robert Cermak and
Georgina Doe feel proud.
“It’s nice because you’re contributing. You’re doing a
lot of hours, it uses a lot of gas, you go around a lot of blocks doing this
kind of count
but we just think it’s important.”
(sound of Georgina Doe walking)
Georgina Doe says she doesn’t really think of herself as a
scientist.
But she’s out there every day, with her ear to the wind. And that’s
what the scientists are counting on.

A recent newspaper report says that the White House stopped the
EPA from issuing a warning about widespread asbestos-contaminated
insulation last spring. The Great Lakes Radio Consortium’s Tracy Samilton
reports:
Zonolite insulation was produced in this country from the 1940’s through
the 1990’s, and almost all of it was made from ore that came from one mine
in Libby, Montana. Thousands of miners were killed or sickened because
the ore was contaminated with an extremely lethal asbestos fiber.
But it was only last year that the EPA decided to issue a public health
emergency warning to residents and workers who could come in contact with
Zonolite insulation in homes where it had been installed.
A St. Louis Post Dispatch investigation revealed that the White House Office of
Management and Budget intervened, and the EPA never issued the warning.
The Post Dispatch reports that EPA chief Christine Todd Whitman was
outraged by the decision.
Hundreds of thousands of homes in Michigan and Illinois probably have
Zonolite insulation. The insulation is often strewn loose in attics.
It’s silvery-brown and comes in feather-light pieces ranging from the size
of a pea to the size of a nickel.

This bread was dumped at a park along a Great Lakes beach for the gulls, geese, and squirrels that live there. Beach visitors often assume high bacteria levels that close beaches to swimmers are solely due to sewer overflows, but animals that defecate in the area also contribute to the problem.
This past summer beaches around the Great Lakes were closed in record numbers because of high bacteria counts. One government study indicates part of the problem might be animal feces, but the public does not seem to be aware that of the connection. The Great Lakes Radio Consortium’s Lester Graham reports:

This past summer beaches around the Great Lakes were closed in record numbers
because of high bacteria counts. One government study indicates part of the problem
might be animal feces, but the public does not seem to be aware that of the connection.
The Great Lakes Radio Consortium’s Lester Graham reports:
High levels of bacteria in the water can make swimmers sick. Cameron Davis is with the
watchdog group, the Lake Michigan Federation. He says more can be done to stop the
contamination if sewer plants are improved and if beach visitors were more aware that
leaving food waste and feeding gulls and geese adds to the problem. That’s because the
birds defecate more, causing higher levels of bacteria along the shore.
“So, we’ve got the sewage treatment agencies saying ‘Oh, no. It’s the geese and the
gulls,’ and we’ve got the people feeding the birds saying ‘Oh, no. It’s sewage treatment
plants.’ So, you can see, it’s a combination of sources and there are things — I don’t care
what anybody says — there are things we can do to help solve the problem with all those
different sources.”
Davis says local governments need to start identifying and eliminating those sources of
beach contamination, starting with improving sewer plants and getting people to clean up
after their visits and to stop feeding wildlife at the beaches.
For the Great Lakes Radio Consortium, this is Lester Graham.
The USDA’s new plan to inspect meat and poultry plants is not yet up to Grade A standards, according to a new government report. The Great Lakes Radio Consortium’s Lester Graham has more:
Toxic waste sites contaminated with PCBs dot industrial areas of the Midwest. Scientists have long believed that the greatest PCB risk for humans comes from eating PCB contaminated fish. A new study challenges that assumption. The Great Lakes Radio Consortium’s David Sommerstein reports:
Mercury emissions from more than 150 coal-burning power plants across the Great Lakes are coming under greater scrutiny this summer. Several states are considering ways to reduce those emissions. Wisconsin could become the first state in the nation to issue rules requiring large mercury reductions. The Great Lakes Radio Consortium’s Chuck Quirmbach has the story:
Communities across Great Lakes region are suffering from an overabundance of Canada Geese. In many cases the solution is to chase them away. Some communities kill the surplus waterfowl and send the meat to food pantries. But in one Wisconsin community the unwanted geese are so full of PCBs the city has had to treat the birds as toxic waste. The Great Lakes Radio Consortium’s Gil Halsted reports:
