When to return home after flooding

UNDATED, (CDC) - Flood waters that enter houses may carry sewage, bacteria, and viruses. People become infected primarily by getting flood water in their mouths, or in some unusual cases, in cuts or open wounds. Some populations, such as the elderly and young children, or individuals with compromised immune systems (such as those getting cancer chemotherapy or with HIV infection) may be at higher risk.

You should not live in a house which has water in it, or items which have been soaked with flood water and are hard to dry. These include carpets and carpet pads, furniture (except furniture made entirely of plastic or solid wood), and any other large items that can soak up and retain water. Usually the best thing to do is to remove them from the house and get rid of them.

• The most important thing you can do to protect yourself when cleaning your house after a flood is wearing protective clothing such as gloves, boots, and good handwashing with soap and water when you're done. (Alcohol-based lotion or gel hand sanitizers work best when any skin dirt is first washed off.)
• When the house is grossly dry, without mud or dirt in it, the chances of infection have been reduced significantly, and healthy individuals may be able to live in it with little risk. There are still likely to be moist areas, or areas with water, such as built-in cupboards on the floor and underneath linoleum tile or hardwood flooring. These areas may pose a risk, although contact with them requires a deliberate effort.
• When the house has been cleaned and disinfected, the level of risk has been reduced as much as possible. At this point, vulnerable populations such as children can live in it.

Several web sites such as CDC's www.cdc.gov/nceh/ehs have information on how to clean a house after a flood, and have links to additional information.
