Biological Hazard in USA on Monday, 14 April, 2014 at 03:03 (03:03 AM) UTC.

Description A Swisher County resident, in Texas’ Panhandle, is the Lone Star State’s first case of Hantavirus Pulmonary Syndrome (HPS) this year, the Texas Department of State Health Services announced Thursday. Health officials believe exposure occurred in a rodent-infested barn when dust was stirred up. They report has recovered from the viral infection. Hantavirus is a life-threatening disease spread to humans by rodents that has symptoms similar to influenza. Hantavirus is carried by rodents, especially deer mice. The virus is found in their urine and feces, but it does not make the animal sick. It is believed that humans can get sick with this virus if they come in contact with contaminated dust from mice nests or droppings. You may come in contact with the dust when cleaning homes, sheds, or other enclosed areas that have been empty for a long time. Hantavirus does not spread between humans. HPS has a mortality rate of 38% according to the agency. Biohazard name: Hantavirus Biohazard level: 4/4 Hazardous Biohazard desc.: Viruses and bacteria that cause severe to fatal disease in humans, and for which vaccines or other treatments are not available, such as Bolivian and Argentine hemorrhagic fevers, H5N1(bird flu), Dengue hemorrhagic fever, Marburg virus, Ebola virus, hantaviruses, Lassa fever, Crimean-Congo hemorrhagic fever, and other hemorrhagic or unidentified diseases. When dealing with biological hazards at this level the use of a Hazmat suit and a self-contained oxygen supply is mandatory. The entrance and exit of a Level Four biolab will contain multiple showers, a vacuum room, an ultraviolet light room, autonomous detection system, and other safety precautions designed to destroy all traces of the biohazard. Multiple airlocks are employed and are electronically secured to prevent both doors opening at the same time. All air and water service going to and coming from a Biosafety Level 4 (P4) lab will undergo similar decontamination procedures to eliminate the possibility of an accidental release. Symptoms: Status: confirmed

Hantavirus Case Prompts Precaution Reminder

News Release
April 10, 2014

The Texas Department of State Health Services offers precaution information after a Texas Panhandle resident recently developed hantavirus pulmonary syndrome, or HPS.
The person is a resident of Swisher County and has recovered from the infection. Exposure most likely occurred in a rodent-infested barn when dust was stirred up. This is the first confirmed case of HPS in Texas this year. One case was reported in the state last year.
Hantavirus is carried by certain species of rats and mice. The illness is rare. Infected rodents shed the virus in their urine, droppings and saliva. The virus can be transmitted to people when infected rat or mouse urine, saliva, droppings or nesting materials are stirred up, temporarily aerosolizing the virus, which can be breathed in by humans. HPS cases are frequently associated with spring cleaning.

DSHS recommends the following precautions.

• Seal openings that may allow rats and mice to enter homes and workplaces.
• Remove brush, woodpiles, trash and other items that may attract rats and mice.
• Tightly close garbage cans, pet food containers and other food sources.
• Wear protective gloves to handle dead mice and rats or to clean up nesting areas, urine or droppings.
• Before cleaning up nests or droppings found inside, open windows and doors to ventilate the area for at least 30 minutes.
• Do not stir up nests by sweeping or vacuuming. Dampen areas before cleanup.
• Use a disinfectant or 1-to-10 bleach-water mixture to clean up dead rodents, nests, urine and droppings.

Early symptoms of hantavirus infection include fatigue, fever and muscle aches. These symptoms may be accompanied by headaches, dizziness, chills, nausea, vomiting, diarrhea and abdominal pain. Later symptoms include coughing and shortness of breath. If hantavirus is suspected, people should contact their health care provider immediately.
A total of 39 HPS cases have been confirmed in Texas since 1993, the first year it was reported, and 14 of those cases resulted in death.
