Colorado 02/13/15 chaffeecountytimes.com: by Maisie Ramsay – Hantavirus caused the death of 53-year-old Buena Vista resident Chris Banning, Chaffee County health officials confirmed Friday. “Chris Banning’s official cause of death was hantavirus pulmonary syndrome,” Chaffee County Coroner Randy Amettis said. Banning died Jan. 11 at Heart of the Rockies Regional Medical Center in Salida. “It was a very sad situation because he was an extremely healthy person,” Chaffee County Public Health director Susan Ellis said. “Your heart just breaks for these types of things. They happen so quickly.” Hantavirus is contracted from exposure to feces, urine or saliva from infected rodents such as deer mice. The disease is rare, but has a high mortality rate, killing about 40 percent of those who contract the virus.

CO-CDPHE_logoFifty cases of hantavirus were reported in Colorado between 2003 and 2013, according to the Colorado Department of Public Health and Environment. During that 10-year period, CDPHE reported only one case in Chaffee County. Chaffee County Public Health evaluated sites where Banning may have contracted hantavirus, but none were identified as the specific source of contamination. None of the sites were public locations, Ellis said. The coroner alerted Banning’s family and others to their risk of exposure. They were advised to watch their symptoms for six weeks following potential exposure. It takes 1-5 weeks before those exposed to hantavirus show symptoms, according to Centers for Disease Control and Prevention. The disease is not transmittable between humans, cats or dogs. – For complete article with symptoms and precautions see http://www.chaffeecountytimes.com/free_content/article_31f01628-b3d8-11e4-9a2a-8b2a52d556a8.html

MAD COW DISEASE:

CANADA:

madcowAlberta 02/13/15 bnn.ca: Canada confirmed its first case of mad cow disease since 2011 on Friday but said the discovery, which helped drive cattle prices higher, should not hit a beef export sector worth C$2 billion ($1.6 billion) a year. The Canadian Food Inspection Agency (CFIA) said no part of the animal, a beef cow from Alberta, had reached the human food or animal feed systems. Mad cow is formally known as bovine spongiform encephalopathy (BSE), a progressive, fatal neurological disease. “The CFIA is seeking to confirm the age of the animal, its history and how it became infected. The investigation will focus in on the feed supplied to this animal during the first year of its life,” the agency said. Canadian exports were badly hit in 2003 after the first case of BSE was detected. Canada subsequently tightened its controls and many nations have since resumed the beef trade with Canada, despite the discovery of more cases since then. Asked whether he was concerned about exports being harmed, Agriculture Minister Gerry Ritz told reporters in Calgary: “Not at this time, no.” He added though that markets in South Korea and Japan were generally very concerned about the potential risk from BSE. A fresh discovery of BSE may not close borders to beef, given the tougher measures, but it could delay Canada’s efforts to upgrade its international risk status from the World Organization for Animal Health (OIE). Ritz said Canada’s current OIE risk status meant it could report up to 12 outbreaks in a calendar year. – For complete article and video see http://www.bnn.ca/News/2015/2/13/Mad-cow-disease-confirmed-in-Alberta-cow.aspx

H5N1 AVIAN FLU:

Canada:

H5N1_46225British Columbia 02/0-9/15 reuters.com: by Sybille de la Hamaide – Canada reported an outbreak of the highly pathogenic H5N1 bird flu virus in the province of British Columbia, the World Organisation for Animal Health (OIE) said on Monday. The outbreak was detected on Feb. 2 in a backyard poultry flock in the province, where bird flu cases of the separate H5N2 strain had been reported in December, OIE said, citing the Canadian Food Inspection Agency (CFIA). The agency stressed that H5N1 avian influenza had not been reported in a commercial poultry flock in Canada and that the virus found in British Columbia was different from a strain circulating in Asia. No human infections have been reported with the H5N1 virus detected in Canada, unlike the genetically different Asian strain, an OIE spokeswoman said. H5N1 bird flu, which first infected humans in 1997 in Hong Kong, has since spread from Asia to Europe and Africa and has become entrenched in poultry in some countries, causing millions of poultry infections and several hundred human deaths. “Based on the limited partial sequence of the H5 and N1 gene segments obtained this far, it appears very likely that this is the same or a very similar virus to the … H5N1 virus in Washington state, but more sequencing will be needed to make a final conclusion,” the CFIA said in its report. – See http://www.reuters.com/article/2015/02/09/us-canada-birdflu-idUSKBN0LD1QL20150209

LYME DISEASE:

dollar-signlyme-disease-awareness-ribbon-mdNational 02/06/15 healio.com: Researchers from Johns Hopkins University reported that the long-term consequences of Lyme disease infection is having a significant impact on the United States health care system — costing upwards of $1.3 billion annually, or almost $3,000 a patient on average. “Routine follow up of patients after initial treatment of Lyme disease may be important to identify those who go on to develop post-treatment Lyme symptoms,” John Aucott, MD, assistant professor of rheumatology at Johns Hopkins University School of Medicine, told Infectious Disease News. “Symptoms of unusual fatigue, new musculoskeletal symptoms, or other unexplained symptoms in a patient recently treated for Lyme disease should raise the question of possible Post-Treatment Lyme Disease Syndrome.” Post-Treatment Lyme Disease Syndrome, or PTLDS, continues to be a controversial topic. Some physicians and patient advocacy groups claim that PTLDS is a chronic condition lasting weeks, months or even years after initial antibiotic treatment has been dispensed, calling it “chronic Lyme disease.” Others argue that there is insufficient evidence of the persistence of viable Borrelia burgdorferi bacteria in PTLDS, and that long-term symptoms like fatigue, musculoskeletal pain and neurological manifestations are unrelated to the infection.

jhu-logoaaCDC-LogoAccording to the CDC, 10% to 20% of patients treated for Lyme disease with the recommended 2- to 4-week course of antibiotics have PTLDS. After initial antibiotic therapy, there are limited treatment options for patients reporting persistent symptoms of Lyme disease. “Our study looks at the actual costs of treating patients in the year following their Lyme diagnosis,” Emily R. Adrion, MSc, a PhD candidate in the department of health policy and management at Johns Hopkins Bloomberg School of Public Health, said in a press release. “Regardless of what you call it, our data show that many people who have been diagnosed with Lyme disease are in fact going back to the doctor complaining of persistent symptoms, getting multiple tests and being retreated. They cost the health care system about $1 billion a year and it is clear that we need effective, cost-effective and compassionate management of these patients to improve their outcomes even if we don’t know what to call the disease.” – For complete article see http://www.healio.com/infectious-disease/zoonotic-infections/news/online/%7Beb7cb6ca-f815-4412-a75f-0ea8ac60b01d%7D/ptlds-costs-estimated-at-1-billion-annually-in-us

RABIES:

520bc0501588c.preview-300Florida 02/06/15 Alachua County: A Rabies Alert has been issued after an unvaccinated dog belonging to a local business owner tested positive for the virus. At least 10 people were treated for potential exposure after it was learned they had been in contact with the 30-pound, black-and-white bull terrier near Gateway Farms at 22413 NW 227th Drive in High Springs. Others who may have been in contact with the dog are being urged to seek immediate medical advice. – See http://www.gainesville.com/article/20150206/ARTICLES/150209708

Maine 04/13/11 onlinesentinel.com: by Erin Rhoda – West Forks —  Excerpts –  “The deer seem to arrive right on schedule. It’s a little after 6 p.m., and the sky is growing dim. As Gordon Berry spreads sweet feed in long lines across the snowy ball fields, some of the more than 100 deer back away and watch him closely. Others jump playfully, ignoring the man in a ballcap who has provided for them for the last 10 years. Behind Berry, two pickup trucks are parked by the Kennebec River, near its confluence with the Dead River. The visitors came to watch the wild, white-tailed deer. In the winter, sometimes as many as 30 snowmobilers will park in the spot off U.S. Route 201 to see them — as if it’s a live drive-in movie. The practice of feeding deer is a controversial one, but in this plantation with 46 residents, it’s become a way of life. The program is funded in part by West Forks and The Forks taxpayers, even though biologists advise against feeding deer.”

West Forks area

“The state wildlife department agrees that Maine needs more deer wintering areas but frowns on supplemental feeding programs. ‘It is a difficult circumstance because the north country has changed quite a bit. The best people can do is try to be advocates for the protection and conservation of wintering areas,’ said Maine deer biologist Lee Kantar. There are a number of reasons why the department discourages the practice of feeding deer. One is that feeding areas are prime places for spreading diseases. A biologist’s worst nightmare, Kantar said, is to learn of deer having chronic wasting disease, a fatal illness that spreads through contact with saliva, feces and urine. Deer also are sensitive to abrupt changes in diet and can die if fed the wrong thing. They need protein-rich food, not kitchen scraps or hay. Even if fed the correct food, deer that are crowded together are prone to fighting one another, Kantar said, preventing the weaker deer, who need food the most, from receiving it. Also, feeding programs often draw deer across roads, increasing the likelihood they’ll be struck by cars.” (For complete article go to http://www.onlinesentinel.com/news/to-feed-or-not-to-feed__2011-04-12.html )

Michigan 04/13/11 livingstondaily.com: by John Schneider – So, how does Department of Natural Resources Wildlife Division Chief Russ Mason feel about lifting the deer-baiting ban? “Asking me that is like asking your physician if you should smoke,” Mason said, adding: “Biologically, baiting is a bad idea.” On the other hand, Mason acknowledges that it’s not strictly about biology. “Maybe there are social reasons (for rescinding the ban),” he said. He also acknowledges that the “great majority” of people with an opinion on the subject don’t like the baiting/feeding prohibition that’s been in effect in the Lower Peninsula since August 2008, and is under review by the Natural Resources Commission.

Among that majority are the folks who, until three years ago, earned at least part of their livelihood growing and selling the sugar beets, carrots, field corn, etc. hunters used to lure deer into shooting range. Then you have the hunters themselves, some of whom believe baiting is a necessary strategy. Then you have the recreational backyard feeders — people who simply enjoy inviting deer to dinner. One common denominator among all these groups is the belief that the ban was an overreaction to a single doe discovered to have chronic wasting disease — a fatal neurological sickness — at a private deer breeding ranch in Kent County. But dramatic action was warranted, DNR officials said, because an outbreak of CWD in the wild deer herd could destroy the deer herd and the state’s hunting industry. The disease is believed to be spread through nose-to-nose contact; hence, the baiting ban.

When the ban was imposed, the Natural Resources Commission promised to revisit the issue in three years. Thousands of Michigan deer have been tested for CWD since 2008, and none have found to be infected. “We’re morally obligated to have this discussion,” Mason said. There have been two public forums on the issue — one in March and one last week — and a third will take place May 12 at an NRC meeting in Flint. Meanwhile, comments can be sent to deerbaiting@michigan.gov.

The commission will decide whether to lift, continue, or modify the ban in June — in time for the July printing of the 2011 edition of the DNR’s annual hunting guide.
Mason said that between the extremes of a complete baiting ban and a return to the pre-2008 permissiveness, there are numerous possibilities that could address quantities and types of bait, as well as other issues. Mason, for one, believes that whatever the NRC decides, it should be applied uniformly throughout both peninsulas. “I think there should be consistency,” he said. “Otherwise, it’s hard to enforce and confusing.”

Tennessee04/13/11 metropulse.com: The Tennessee Wildlife Resources

Deer with CWD

Agency is fighting a bill that would allow private game preserves in Tennessee to import white-tail deer, arguing that such a move might introduce Chronic Wasting Disease into wild deer populations in the state. The bill requires that such deer be tested for CWD, but TWRA argues it is too risky. The bill has now been amended to say that deer cannot be imported into Tennessee by any entity (including TWRA) from a state in which there has been an outbreak of CWD. That would limit the importation to only 11 states. But under the legal definition, elk imported by TWRA in an effort to build up state herds are “deer.” TWRA would be under the same restriction as a game preserve not to bring in animals from states where there have been cases of CWD. TWRA allies did defeat an amendment that would have required the agency to test any deer that dies in a wildlife area for CWD, arguing it was too costly. Meanwhile, the deer farming bill has been moved from the TWRA-friendly Environment and Conservation Committee to the farm-friendly Agriculture Committee.

Wisconsin 04/14/11 kstp.com: by Leslie Rolander – State wildlife officials want to scale back Wisconsin’s contentious October antlerless deer season. The Department of Natural Resources’ draft of this fall’s deer hunting season structure calls for eliminating the four-day October hunt in 95 management zones where the deer population is substantially above goal. Hunters could still purchase $2 antlerless tags for other seasons in those zones. The plan also allows antlerless kills in 10 northern zones where they were prohibited last year, reflecting a rebounding population. Hunters in the chronic wasting disease zone, meanwhile, would be allowed to make their first kill a buck or doe. Earn-a-buck requirements would apply after that, meaning hunters must kill an antlerless deer before they can take a buck. The DNR’s board will take up the proposal later this month.

CDCMorbidity and Mortality Weekly Report 04/15/11 / 60(14);437-440: On

Silver-haired bat

November 9, 2009, a Michigan hospital informed CDC of suspected rabies in a man aged 55 years. The patient reportedly had awakened with a bat on his arm 9 months earlier but had not sought medical evaluation. He went to a local emergency department (ED) on October 30 and soon after was hospitalized; he died 12 days later. On November 14, CDC confirmed infection with a rabies virus variant that commonly infects the silver-haired bat (Lasionycteris noctivagans). This report summarizes the patient’s clinical course and the associated public health investigation. The report highlights the importance of public awareness of rabies, particularly among persons who might be at risk for wildlife exposures. Persons who experience contact with a bat and cannot confidently rule out a bite or scratch should seek prompt medical attention.                (For complete report go to http://www.cdc.gov/mmwr/preview/mmwrhtml/mm6014a1.htm?s_cid=mm6014a1_e&source=govdeliv )

National 04/13/11 cnn.com: by Ann J. Curley, CNN Medical Assignment Mgr – Dengue fever, common in tropical and subtropical areas of the world that are home to more than a third of the world’s population, has been a rarity in the United States – until a couple of years ago. But in 2009, dengue infection appeared in a few Florida residents who had not traveled out of the U.S., ending a 45-year absence from the United States, according to the CDC. The number of U.S. hospitalized cases of dengue infection more than tripled between 2000 and 2007, according to a study published Wednesday in the April issue of Emerging Infectious Diseases.

After reemerging in Florida, dengue was placed on the U.S. list of “reportable diseases” in January 2010, requiring laboratories and heath care providers to report all U.S. cases of dengue to the CDC. The reporting system allows public health officials to monitor the U.S. incidence of dengue, which, the report says has been described as a potential public health threat for residents of the U.S. mainland, noting that the vector mosquitoes have spread to at least 26 states in the U.S. mainland.

Dengue fever is one of four closely related viruses that are spread to humans by infected mosquitoes. Symptoms of dengue fever include high fever, severe headache, severe pain behind the eyes, joint pain, muscle and bone pain, rash and mild bleeding of the nose or gums, as well as easy bruising. Dengue hemorrhagic fever is a severe form of infection that can be fatal if it’s not quickly diagnosed and treated. However, when properly recognized and treated, death due to the virus can be less than 1%. The only way to prevent dengue is by controlling mosquitoes and preventing their bites.

Researchers from the University of Iowa analyzed U.S. trends in dengue diagnosis among hospitalized patients using data from the National Inpatient Sample, a database of hospital discharges in the U.S. From 2000 to 2007, 1250 patients were hospitalized with dengue fever. The number of dengue hospitalizations rose from 81 cases in 2000, to 299 cases in 2007– results that show hospitalizations more than tripled during the study period. The study notes that the increase is not surprising because the number of dengue cases in areas where it is commonly found have increased in recent years, and also because of the large number of travelers who enter the U.S. from tropical and subtropical regions.

Given the documented increases, researchers concluded that requiring the reporting of dengue was warranted and that continued vigilance is needed. The World Health Organization calls dengue a major international public health concern that places 2.5 billion people–two-fifths of the world’s population, at risk. There may be 50 million dengue infections worldwide each year, according to WHO data.

CDC Emerging Infectious Diseases Vol. 17, No. 5 (May 2011): Babesiosis, a

Deer tick

potentially deadly disease, is emerging in the Lower Hudson Valley, just north of New York City. The disease is caused by a parasite that destroys red blood cells. Since first appearing in the Lower Hudson Valley in 2001, babesiosis cases have increased 12 times faster in the this area than in the rest of the state. Cases are occurring mostly in residents who were bitten by ticks or had been treated with blood products. The risk is highest for people with weakened immune systems.

Colorado04/14/11 Colorado Department of Public Health & Environment:

Deer mouse

Lori Maldonado, Deputy Director – Denver – As spring cleaning nears, state health officials are warning Coloradans to avoid exposure to hantavirus when opening up cabins, buildings, sheds and barns. Hantavirus is a respiratory disease carried by deer mice. Deer mice are brown on top and white underneath. They have large ears relative to their head size. House mice are all gray and have small ears and don’t carry the disease.  Hantavirus is transmitted by inhaling dust contaminated with the virus in a mouse-infested area.  Already this year, hantavirus has claimed the life of an individual in Southwest Colorado and sickened another in Weld county. Colorado averages about four cases of hantavirus a year. In 2010, five cases and two deaths were reported. Elisabeth Lawaczeck, state health veterinarian with the Colorado Department of Public Health and Environment, said, “Now is the time when people begin cleaning out barns, garages, storage buildings, sheds, trailers or cabins that have been closed up all winter. They need to take precautions need before beginning such work, particularly if there are mouse droppings and other signs of mice. Be particularly vigilant where there are mouse droppings and evidence that mice have been in and around the buildings or nearby wood or junk piles.”

Florida 04/13/11 floridatoday.com: by J.D. Gallop – Brevard County Health Department has issued rabies alert for a residential area in Cocoa. The alert was issued today after tests determined that a raccoon found near Skyway Drive in Cocoa was infected with the deadly virus. Earlier this month, health officials determined that a raccoon found on Allendale Street in Titusville had rabies.

Maryland 04/13/11 exploreharford.com: According to the Harford County Health Department, only 11 rabies-positive animals were identified in 2010, compared to 16 in 2009 and 23 in 2008. About 75 percent of the animals testing positive for rabies were raccoons, which typically provide the highest risk and most common exposure route to domesticated animals. Three rabies positive raccoons have been documented in the first two months of this year, the health department said. In all three cases, pets were exposed to the raccoon, but the pet was adequately protected because it was vaccinated.

North Carolina 04/13/11 charlotteobserver.com: The Mecklenburg County Health Department is advising residents in a portion of east Charlotte to use caution near wild animals, after a raccoon tested positive for rabies. The health department said a resident of the Hickory Ridge neighborhood, off Pence Road east of W.T. Harris Boulevard, spotted a raccoon with unusual behavior late last week. The animal was found to be rabid. The raccoon was found near Fringe Tree Drive, at the southern edge of the neighborhood. Health department officials say there is no indication that the raccoon had contact with humans.

Texas 04/13/11 elgincourier.com: by James Worsham – Rabies is an ever-present danger in rural areas and a growing concern in larger communities as well. As recently as March 30 an infected animal was found in the Elgin area. “I saw the bat flopping around the sidewalk in my backyard,” said Ellette Vinyard of the animal rescue group Companion Connection. She said her husband killed it with a shovel and Bastrop County Animal Control picked it up and called her back to tell her it was infected with rabies.
