California 09/13/12 by Kate Mather – Another person was sickened by hantavirus traced to Yosemite National Park, the latest in an outbreak that has grown to nine cases and has killed three visitors since mid-June. The latest case, which sickened a California resident, is believed to have originated in one of Curry Village’s signature tent cabins in early July, park spokesman Scott Gediman said. A total of eight cases have been linked to the insulated signature tent cabins; the other to the High Sierra Loop that connects Yosemite Valley with Tuolumne Meadows and other areas. But the latest case differs from the others in that it was considered a “hantavirus infection,” officials said. Although very rare, some hantavirus cases don’t show the respiratory symptoms found in hantavirus pulmonary syndrome, according to the California Department of Public Health. The eight other cases tied to Yosemite developed into the full-fledged hantavirus pulmonary syndrome. The person with the hantavirus infection has since recovered, Gediman said. The park received confirmation of the case Thursday morning. – For complete article see

California 09/12/12 Rubicon Bay, El Dorado County: Animal Services is searching for the owner of two German Shepherds that bit a 68-year-old woman while she was walking in Rubicon Bay, according to a Monday statement from the county. The incident happened about 4:45 p.m. Aug. 31. on Highland Drive when the dogs, off leash and running alongside their owner’s truck, approached the woman and bit her on her leg, according to the statement. The owner of the dogs stopped and allegedly provided incorrect contact information to the woman, who suffered non-life-threatening injuries. Animal Services officers are looking for the dogs’ owner to verify the dogs are current on their rabies vaccinations. Without this verification, the woman may need to have post-exposure rabies treatments, according to the statement. The county asks anyone with information to contact Animal Services at 530-573-7925.

New York 09/12/12 Batavia, Genesee County: The mother of a boy who was bit by a dog two days ago is getting nervous. Nobody has come forward yet as the owner of the dog, and no Good Samaritan has helped by identifying the dog and its owner. That leaves a week left to try and find the dog and determine whether it carries rabies. Without the confirmation, her boy will need to go through a painful round of rabies shots. After further discussions with the boy, more details are available on the man and his dogs. The man is described as about 6-feet tall, older and with a potbelly.  The dog that bit the boy is likely a mix breed. After looking through photos with her son, the mother does not believe the dog was a pit bull. Its face was droopier and had longer ears. The dog was brown and black and brindled (stripes). The owner was walking it with a harness (rather than a collar). The man was also walking a slightly smaller yellowish dog. The boy encountered the dogs on Vine Street near John Kennedy School. It’s likely the owner lives within a quarter mile of the school since that’s the neighborhood he was walking in. The man has not been seen in the neighborhood since. Anybody with information that may assist in locating the dog, please call Batavia PD at (585) 345-6350.

Rhode Island 09/12/12 Jamestown, Newport County: A stray kitten that had been adopted by a resident in the area of Highland Drive near Fort Wetherill state Park and then died has tested positive for rabies.

It is assumed they were all exposed to the virus and might all be infected. – See
