How long the virus survives—and where it thrives The novel coronavirus can survive on surfaces anywhere from hours to days. The latest information is that it can last 24 hours on cardboard, 48 to 72 hours on plastic, and 48 to 72 hours on stainless steel, says Dr. Reuben Elovitz , internist and CEO at Private Health Dallas , who cited a recent study from the New England Journal of Medicine . The duration also depends on a few other factors, like temperature and whether a surface is prone to holding moisture. “Wooden handles, for example, are more likely to be damp than metal under normal conditions—and damp conditions can enable many infectious agents to thrive,” explains molecular biologist Dr. Tracey Evans . “ Furthermore, a warm room is more favorable for many pathogens than a cold one.” Regardless of what kinds of temperatures and surfaces you have in your home, there are things you can do to keep these dangerous pathogens at bay.

1. Shade the Sidewalk Consider placing a tree where it will shade the sidewalk to help create a pleasant environment and encourage walking and visiting among neighbors. Trees provide rain and sun protection, and temperature differentials of 5 to 15 degrees are felt when walking on tree-canopied streets. In urban areas trees help mitigate the heat-island effect and provide a connection to nature. Most cities require permits for adding trees to a parkway (or hell strip), but permits are not usually required for planting on private property. Sean Papich Landscape Architecture 2. Set the Fence Back Placing a low fence or wall back a few feet from the edge of the sidewalk allows room for planting, and plants provide visual interest for pedestrians. In addition to cheerful daisies like these, velvety plants such as lamb’s ears ( Stachys byzantina ; USDA zones 4 to 9; find your zone ) would work well. June Scott Design ...
Linear Lighting There’s a trend toward the more extensive integration of lighting with modern hardscape elements. Sleek, minimalist linear step lighting illuminates a path while keeping light fixtures hidden from view. It also enables you to more easily highlight an architectural feature, such as stairs or a freestanding wall. ZEN Associates, Inc. Laurie Ghielmetti Floating Structures Another trend is placing lights beneath landscape structures, creating the illusion that they are floating-- light is hidden to visually float steps, benches, bridges and other outdoor landscape elements. dSPACE Studio Ltd, AIA BEGA North America Sleek, Modern Fixtures A big trend is to use path lights that look more architectural, rather than the traditional flower or mushroom shapes.
