Home Environment and Traveling Home Environment Taking a few simple precautions can help protect you from infections at home. Generally, pets that have been in the home may remain. Avoid contact with bodily excretions, urine, and stools of animals, birds, and fish. You should avoid contact with soil for several months or until your nurse practitioner and physician inform you otherwise. Thorough hand washing after touching animals, plants, and soil is essential. You may find it beneficial to use cool mist humidification to add moisture to the air in your home, especially during the winter months. It is important that the system you use is thoroughly cleaned on a regular basis by someone other than yourself. Traveling Speak to your nurse coordinator, nurse practitioner, or physician before making travel plans for the near future.
