Texas 06/01/16 click2houston.com: The Texas Department of State Health Services confirmed Tuesday the first locally acquired case of chikungunya, a mosquito borne illness. A Cameron County resident got sick with the illness in November 2015 and was diagnosed in January. The case was reported to the local health department in April. The investigation performed by the Cameron County Department of Health and Human Services determined the patient had not traveled, and the case was confirmed last week by testing at the US Centers for Disease Control and Prevention. – For complete article see http://www.click2houston.com/health/first-texas-acquired-chikungunya-case-announced

According to the University of Minnesota, three cases of tularemia or rabbit fever in domestic animals have been found since April. The cases have been identified in a cottontail rabbit and two cats – all in the Twin Cities metropolitan area. The disease is rare in Minnesota.

Texas 05/02/16 rgvproud.com: Cameron County Department of Health and Human Services has been investigating a probable case of Chikungunya virus infection. This case initially presented to a doctor’s office in November 2015 and tested in January 2016; however, it was not reported to the health department until April 2016. The investigation has since determined that the case was acquired locally and is being considered the first locally acquired probable case of Chikungunya in the State of Texas. Chikungunya virus is transmitted to people through mosquito bites and cannot be spread from one person to another person. The most common symptoms of Chikungunya virus infection are fever and joint pain. Other symptoms may include headache, muscle pain, joint swelling, or rash. Should anyone experience any of these symptoms, a visit to the health care provider should be scheduled. “While this is the first reported locally acquired probable case of Chikungunya, the overall risk of being infected with Chikungunya virus in South Texas is very low and we have no additional evidence that the virus is circulating in the local mosquito population,” stated James W. Castillo, Cameron County Health Authority. “A critical key point to also remember here is the importance of physicians reporting these conditions. It would have allowed us to work with our local municipalities to assess the mosquito issue and appropriately respond.” – For complete article and preventive measures see http://www.rgvproud.com/news/local-news/cameron-county-reports-probable-case-of-chikungunya-in-texas

The rabbit was found in the Liberty Point area. The Pueblo City-County Health Department said it had no contact with people. Tularemia is a bacterial infection most commonly transmitted to humans by the handling of sick or dead animals. Infection can also occur from the bite of infected insects, including ticks and deer flies, and exposure to soil and vegetation. Dogs and cats get tularemia by eating infected rabbits or other rodents and through tick and deer fly bites. – See http://fox21news.com/2016/05/05/wild-rabbit-found-in-pueblo-west-tests-positive-for-tularemia/

Deer with CWD

Wisconsin 05/05/16 startribune.com: by Todd Richmond – A prominent sportsmen’s group wants Gov. Scott Walker to crack down on captive deer farms as he considers revising the state’s chronic wasting disease tactics. The Wisconsin Wildlife Federation’s letter to Walker, announced Thursday, asked him to impose regulations designed to keep CWD from spreading from captive deer to wild deer. The recommendations include requiring farms to double fence, installing warning devices that can detect open gates and annual fence inspections by the state or an independent inspector. The letter also suggests that farmers be required to inspect their own fences at least monthly and immediately after any major wind storms. They would have to kill their herds within a month if they haven’t double fenced and one of their deer tests positive for CWD. They also would have to maintain liability insurance to cover any damages to the state resulting from escapes. The DNR recorded 29 escapes from deer farms in 2015 alone. Nevertheless, the agency in December adopted an emergency rule allowing farmers to opt of the state’s CWD program without upgrading their fences. – For complete article see http://www.startribune.com/wildlife-group-proposes-deer-farm-crackdown-to-fight-cwd/378266561/

Black Bear:

black-bear-backcountry-movie_hSaskatchewan 05/05/16 cbc.ca/news: by Stefani Langenegger – A Saskatchewan woman says it was both her scariest and her luckiest day — she fought off a black bear after it bit her on the leg during an afternoon walk. Raschel Zeschuk lives in Paradise Hill, northeast of Lloydminster, and goes on daily walks with her two dogs. But on April 21 the walk was anything but routine. Zeschuk had just reached the end point of her usual route and turned around to return home when she heard rustling behind her. Behind her dog was a black bear in hot pursuit. She says she started to scream in an effort to scare the bear off and looked around for higher ground. “All I could kind of think of was, ‘Get up on something,'” Zeschuk said. She began running towards some poplar trees which had fallen over in the bush.  “The bear immediately turned away from my dog and started chasing me,” Zeschuk said. “It caught up to me pretty fast.” The bear grabbed her leg, scratching it on one side and biting it on the other. Zeschuk scrambled up on the poplar tree, which gave way and she fell backwards. “This is where it’s kind of hazy,” she said. Her dog, Cosmo, began barking and Zeschuk had time to scramble back up on the tree. “It started trying to climb up after me and that’s when I kicked it in the nose as hard as I could and it ran off,” she said. Zeschuk says she then ran home as quickly as she could. She has six stitches in her leg and is getting her last rabies shot today.  Zeschuk says she loves hiking and is working with someone to overcome her anxiety about future walks, given her recent experience. Mostly she just feels very grateful. – For complete article and photos see http://www.cbc.ca/news/canada/saskatchewan/sask-woman-fights-black-bear-1.3567714

WEST NILE VIRUS:

phacCanada 03/18/15 outbreaknewstoday.com: by Robert Herriman – While the United States saw well over 2,000 West Nile Virus (WNV) cases and 85 fatalities during 2014, our neighbors to the north saw just a tiny fraction of that amount. According to the Public Health Agency of Canada, a total of 21 human clinical cases of West Nile virus were reported in Canada, all from 3 provinces. To put that number into perspective, North Dakota, in the northern plains of the US bordering Canada reported 22 WNV cases. Approximately half the Canadian cases were of the more serious neuroinvasive variety, while the other half were not. No WNV fatalities were reported in 2014. The mosquito borne viral disease was reported from Manitoba (5), Ontario (10)  and Quebec (6).v – See http://outbreaknewstoday.com/canada-reports-21-west-nile-virus-cases-in-2014/

More than 70 percent of the cases in the state have been reported in the beach resort city of Acapulco. Other areas in Guerrero reporting chikungunya cases include 15 in the region of Costa Chica, six cases in Zihuatanejo and two more in Petatlán. There has been no fatalities reported. Health authorities have launched mosquito awareness and extermination campaigns in the coastal regions of the state. Beginning in October 2014, the first locally transmitted cases of chikungunya were reported in Mexico. Local transmission means that mosquitoes in Mexico have been infected with chikungunya and are spreading it to people. The Pan American Health Organization (PAHO) has reported 405 confirmed autochthonous and 21 imported chikungunya cases as of Mar. 20. – See http://outbreaknewstoday.com/mexico-chikungunya-cases-top-400-dozens-reported-in-acapulco-15359/

California 02/25/15 berkeley.edu: by Sarah Yang – Birds are more important than previously recognized as hosts for Lyme disease-causing bacteria in California, according to a new study led by UC Berkeley researchers. The findings, published today (Wednesday, Feb. 25) in the journal PLOS ONE, shine a light on an important new reservoir in the western United States for the corkscrew-shaped bacterium, Borrelia burgdorferi, responsible for Lyme disease. Wood rats, western gray squirrels and other small mammals have been identified in previous studies as wildlife hosts of the Lyme disease spirochete bacterium in California, but fewer studies have looked at the role of birds as reservoirs.

“The role of birds in the maintenance of Lyme disease bacteria in California is poorly understood,” said study lead author Erica Newman, a UC Berkeley Ph.D. student in the Energy and Resources Group and the Department of Environmental Science, Policy and Management. “This is the most extensive study of the role of birds in Lyme disease ecology in the western United States, and the first to consider the diversity of bird species, their behaviors and their habitats in identifying which birds are truly the most important as carriers.” Moreover, the birds in the study that were found to be important hosts of Lyme disease bacteria, such as American robins, dark-eyed juncos and golden-crowned sparrows, are coincidentally ones that are commonly found in suburban environments. – For complete article see http://newscenter.berkeley.edu/2015/02/25/birds-lyme-disease-bacteria/

CHIKUNGUNYA FEVER:

index445Global 03/01/15 outbreaknewstoday.com: by Robert Herriman – The chikungunya epidemic in the Western hemisphere has increased by 3,000 cases during the past week with the new tally at 1,247,000 since the first autochthonous cases were reported on the Caribbean island of St. Martin in December 2013, 183 fatalities have been reported. Countries reporting an largest increase in cases include Puerto Rico (1,700) and El Salvador (1,383). The Dominican Republic and Colombia continue to have reported the most cumulative cases to date with 539,183 and 177,187 cases, respectively. In 2015 to date, the United States has seen 43 imported chikungunya cases from 13 states as of Feb. 24. During 2015, no locally-transmitted cases have been reported from U.S. states. In the Pacific, the French Polynesia outbreak is at more than 69,000 estimated cases since 10 October 2014, as of 25 January 2015. 728 hospitalizations, 48 severe cases, 9 fatal cases have been documented. Officials say the outbreak is decreasing. Elsewhere in the Pacific Islands, Samoa has reported 4,431 cases since 21 July 2014 as the outbreak winds down. Chikungunya outbreaks are increasing in New Caledonia (50 cases), the Cook Islands (83) and Kiribati (36). Chikungunya is a viral disease transmitted by the bite of infected mosquitoes such as Aedes aegypti and Aedes albopictus. It can cause high fever, join and muscle pain, and headache. Chikungunya does not often result in death, but the joint pain may last for months or years and may become a cause of chronic pain and disability. There is no specific treatment for chikungunya infection, nor any vaccine to prevent it. Pending the development of a new vaccine, the only effective means of prevention is to protect individuals against mosquito bites. – See http://outbreaknewstoday.com/chikungunya-update-for-the-americas-and-the-pacific-islands-67012/

Author’s Note: The CDC confirmed more than 2,340 cases of Chikungunya fever imported to the United States last year, and 11 locally transmitted cases last year in Florda. – See TEXAS county preparing for CHIKUNGUNYA outbreak posted on this blog January 19, 2015.

~ ANNOUNCEMENT ~

garcThe Global Alliance for Rabies Control (GARC) is pleased to announce the launch of the first of its online education programs, the Rabies Educator Certificate (REC). This is a free web-based course for individuals such as community educators and health workers who would like to learn about rabies and how to teach others to prevent rabies and reduce deaths in their communities. The REC has been developed to help meet the need to effectively disseminate accurate, life-saving information to at-risk communities.

The course is open to anyone but aimed specifically at people who work regularly in these communities, and who are in a position to address community education on rabies. These people may be health/veterinary/community personnel who regularly visit communities, or it may be key people within the communities themselves who want to do something about rabies education.

This online course has five modules:

  • What is rabies and how do people and animals get the disease?
  • How to avoid dog bites and prevent rabies
  • Caring for animals
  • Understanding the role of a community educator in preventing dog bites and rabies
  • Communicating with people

Each module contains specific and clear information that should be applicable to all situations, regardless of geographical location and circumstances.

Participants can access the course at education.rabiesalliance.org. It is self-paced, so participants can complete it in their own time, although it should take between four and seven hours in total depending on previous knowledge and experience. For those with slow or intermittent internet access, the whole course can be downloaded and studied offline. On passing a final online assessment, participants receive a certificate of achievement and should be ready to provide life saving information to their target communities.

This is the first of GARC’s new online courses, and there are plans to provide it in other languages besides English by the end of the year.  We look forward to hearing the feedback of stakeholders and participants: please join the course at education.rabiesalliance.org and share this information with your networks. GARC is grateful to Crucell for its generous support for the development of this course. For queries or more information, please contact us here – See more at: http://rabiesalliance.org/media/news/online-course-for-rabies-educators-launched#sthash.udL5Q2tt.dpuf

Author’s Note: I asked GARC: “Will the new on-line Rabies course also cover feral cat colonies and the rabies threat they pose to local communities? You specifically mention dogs, but not cats.”

GARC’s response: ” The REC course focuses primarily on canine rabies seeing as 90% of rabies deaths in developing countries are associated with dog bite cases. The REC course does however mention the fact that any warm blooded mammal is susceptible to the disease and that any animal bite case should be treated as a potential exposure. We will be revising the course contents annually and I have noted that this is a potential focus point once we revise. Thank you for the valuable feedback. Kind regards, Andre Coetzer, Course Facilitator, GARC Education Program”

North America 02/01/15 utsandiego.com: by Deborah Sullivan Brennan – (Excerpts)

Coyotes have attacked at least 122 people between 1977 and 2008, including a three-year-old Glendale girl who died from the bites in 1981, according to two California professors who have chronicled the animals’ run-ins with humans in urban areas. Coyotes typically flee people, but frequent contact with humans can embolden them, with dangerous results.”

CalPolyLogo” Rex Baker, a professor emeritus of agricultural biology at Cal Poly Pomona, has spent years documenting the animals’ urban exploits, and believes the problem of coyote aggression is increasing. He and colleague Robert Timm, a researcher for the University of California’s agricultural extension, monitored reports of coyote attacks in the U.S. since 1977. California saw far more incidents of coyote aggression than any other state, with the 122 documented reports between 1977 and 2008. Arizona had 37 attacks during that time, Colorado had 12 and all remaining states had fewer than 10.”

anr445” In 1981, a three-year-old Glendale girl, Kelly Keen, was fatally attacked by coyotes while playing in her front yard. Two coyotes killed a19-year-old Canadian woman, Taylor Mitchell, as she hiked alone in Cape Breton Highlands National Park in Nova Scotia in 2009. There have been other close calls. During one week in 2008, three young children were threatened or bitten by coyotes in San Bernardino County. In one of those incidents, a coyote grabbed a two-year-old girl by the head and tried to drag her from her yard in Lake Arrowhead, releasing her when the toddler’s mother approached. A week later, a nanny wrestled a two-year-old girl from the jaws of a coyote at a Chino Hills park.” – For complete article see http://www.utsandiego.com/news/2015/feb/01/san-diego-urban-coyote-bite/2/?#article-copy

CHIKUNGUNYA:

THR_Nov_2014_pp68_01Global 02/02/15 immortal.org: by Christine Layton – A new study has found that Chikungunya virus and rheumatoid arthritis present similar symptoms and even test results, emphasizing the importance of accurate diagnosis. Chikungunya is transmitted by mosquitoes and it’s typically diagnosed in Central and South America, India, the Caribbean and Africa. Symptoms include fever and a rash, as well as severe joint pain that can last for weeks or up to one year. While mosquito-borne diseases are common in humid, equatorial areas, Chikungunya has made its way through Florida in recent years. In fact, the FDA may approve an experiment to release millions of genetically modified mosquitoes in Florida to combat dengue and Chikungunya in the United States. Researchers from the Washington University School of Medicine in St. Louis found that patients with rheumatoid arthritis often have the same symptoms, which may result in an inaccurate diagnosis and treatment, according to the Voice Chronicle. The researchers recommend doctors consider the travel and medical history of patients to avoid a misdiagnosis, as patients who have Chikungunya may be treated with medication for rheumatoid arthritis, which can worsen the condition, according to Daily Science Journal. With this new information about Chikungunya virus, health officials are concerned that the disease could become a diagnostic challenge over the new few years as the virus continues to gain ground in the United States. As blood samples are similar for rheumatoid arthritis and Chikungunya virus, doctors hope immune-suppression drugs that treat arthritis may help, according to Diabetes Insider. – See http://www.immortal.org/5037/chikungunya-virus-shows-similar-symptoms-rheumatoid-arthritis-may-cause-misdiagnosis/

HANTAVIRUS:

Harvest mouse.

Harvest mouse.

California 02/01/15 outbreaknewstoday.com: Two western harvest mice tested positive for the potentially deadly hantavirus in the Fairbanks Ranch area of San Diego County, according to environmental health officials. This prompted officials to remind people to be careful whenever they find signs of rodents living in homes, sheds and garages. Officials said hantavirus is common in San Diego County, but people have very little chance of being exposed to it as long as wild rodents remain out of people’s living spaces. Infected rodents shed hantavirus through their saliva, urine and feces. Officials said people should never try to sweep or vacuum up rodent nests or droppings in homes and work places because it could stir hantavirus into the air where it can be breathed in if rodents are infected. “The best way to protect yourself is to avoid being exposed to rodents, by keeping them out of the areas you live in and work in,” said County Director of the Department of Environmental Health, Elizabeth Pozzebon. “But if you have to clean an area, be sure to use ‘wet-cleaning’ methods — ventilate areas, spray them with bleach solutions or disinfectants and use sponges and mops.” People who inhale the hantavirus can develop hantavirus pulmonary syndrome, which starts with flu-like symptoms but can grow into severe breathing difficulties that can kill. There is no vaccine or cure for hantavirus. The National Centers for Disease Control and Prevention report that hantavirus kills nearly 40 percent of the people who get it.

Montana 01/17/15 missoulian.com: Scientists at Rocky Mountain Laboratories have discovered the Bitterroot Valley is home to a tick that carries the bacteria that causes relapsing fever. Relapsing fever is a treatable, acute, usually nonfatal disease that can make patients sick over and over again. If not treated, it can be fatal to the fetus of a pregnant woman. A paper about the Bitterroot tick was published recently in the scientific journal Emerging Infectious Diseases. The soft tick is different from the larger hard-shelled tick that causes Rocky Mountain Spotted Fever. “You don’t pick them up while hiking through the woods,” Tom Schwan, a Rocky Mountain Laboratories entomologist. Schwan, who co-wrote the paper with a Missoula doctor, said the ticks feed much more quickly than the Rocky Mountain Spotted Fever tick. “Most people don’t know when they’re being bitten by these ticks,” he said. He said chipmunks and squirrels are hosts to the tick.

Dr. Tom Schwan

Dr. Tom Schwan

In 2013, his team of scientists took blood samples from a chipmunk that was trapped near where a man got relapsing fever. The man was bitten by a soft tick while working in his woodpile. Schwan said that chipmunk was infected with the same bacteria that the man who fell ill was infected with. He said finding the infected chipmunk, plus infected ticks in the woodpile, explained how the man became sick with tick-borne relapsing fever. “This is an important bit of evidence to help in the future when people get infected with this disease, so they can get the proper diagnosis and prompt treatment with the appropriate antibiotics,” Schwan said. The scientist thinks these ticks may be fairly widespread in the valley. – For complete article see http://missoulian.com/news/local/tick-with-relapsing-fever-found-in-bitterroot-valley/article_678e09d4-5237-5f64-8995-fabc4c1c9a09.html

CHIKUNGUNYA FEVER:

chickV3399384Puerto Rico 01/18/15 outbreaknewstoday.com: by Robert Herriman – The number of chikungunya cases reported in Puerto Rico from Nov. 26 to Dec. 23 is 431 suspected and 45 confirmed, according to the Departmento de Salud de Puerto Rico. Health officials do say that due to a delay in laboratory testing, the actual numbers may be higher for the period. This brings the cumulative total for 2014 on the Caribbean island to 25,234 suspected cases and 4,227 laboratory confirmed cases. In 2014, Puerto Rico has reported 10 deaths due to chikungunya infection. 31 cases have been seen due to travel. – See http://outbreaknewstoday.com/puerto-rico-chikungunya-death-toll-now-at-10-38236/

339948i5Texas 01/16/15 wfaa.com: by Janet St. James – Dallas County mosquito experts are already prepping dozens of traps specially designed to capture mosquitoes that spread the Chikungunya virus, or ChikV. “This has a lure inside that basically smells like human skin,” explains Dallas County Health and Human Services microbiologist Spencer Lockwood. People are like perfume to ChikV mosquitos. The county has purchased 30 traps for the fight against ChikV. Chikungunya is a virus passed to people by two species of mosquitoes: Aedes albopictus and Aedes aegypti. The infection is characterized by sudden onset of fever and severe joint pains. The most serious symptoms last from two to seven days, but patients have been known to experience joint pain for weeks or years after infection.
