S.V.
Hanta Virus is the most common disease mice can carry. Although, it isn't commonly passed to humans--since we know so much about it now. Never sweep up droppings, use a mask and a wet towel. Trap them (I know this is inhumane, but peanut butter in a gluestrip trap is the one most recommended), bag and actually leave (sealed) in the garage for a few weeks (if anyone gets sick, the doctor will want the rodent). Finally, cleaning items requires bleach. If you suspect the mouse has run in a certain area of your home, spray with a bleach/water mixture. Rule of thumb...books: trash them (if they are SUPER important to you--you can place them outdoors in the sun for a week, no research if this actually kills the virus), clothing: wash in hot water with regular detergent, glassware/silver: spray with bleach solution.
Do all of this while wearing protective gear: Gloves, a mask and long sleeve shirt and pants. Upon removal of clothing, immediately wash in hot water with detergent. Throw mask/gloves away in a sealed bag.
* symptoms: flu like, mostly respiratory symptoms occur, including a fever. This can occur up to 1 week post-exposure. Here in the MO/KS area, there have been many cases. You can call the Health Department with any more concerns.
You can also review info at the CDC: http://www.cdc.gov/rodents/cleaning_up/index.htm
I have an MPH (Master of Public Health) and focused on disease transmission human-to-human. Hanta Virus is not able to pass from human to human...therefore, if someone in the household was infected, quarentine isn't necessary.
Another thing--you might want to contact a pest control service. They have "green" products they can surround your home with that creates a barrier. It's not 100% effective, but does reduce the incidence of rodents in the home.
Other ways of avoiding future infestations: seal all food products (dog food in a sealed rubbermaid), no food on the floors, all garbage cans should have a top to seal them (they can smell garbage up to 500 feet away!), and consistently have traps out in dark areas (cabinets, closets, basements, garages, etc).
Good luck...let me know how it goes. Not to mean to scare you, the incidence rate of Hanta Virus in healthy individuals who are not immuno-suppressed is low. It's usually the elderly or other immuno-suppressed persons who wind up infected. But...you're right to be worried. Just stick to the guidelines above and check out CDC's site. They have an 800 number so you can chat directly with an MPH (public health official) and ask advice...don't hesitate to do so.
Let me know if you need any other info!!!
