The Ebola virus can live on surfaces in hospitals for nearly two weeks, a new study suggests.

Researchers tested how long the Ebola virus could survive on plastic, stainless steel and Tyvek, a material used in Ebola suits. The researchers also simulated different environmental conditions, including a climate-controlled hospital at 70 degrees Fahrenheit (21 degrees Celsius) and 40 percent humidity, and the typical environment of West Africa, at 80 F (27 C) and 80 percent humidity.

In general, the virus survived on surfaces for a longer time when in the climate-controlled conditions than in the West African environment, the study found. Under hospital-like conditions, the virus lived for 11 days on Tyvek, eight days on plastic and four days on stainless steel. The longest the virus was able to survive in the tropical conditions of the West African environment was three days, on Tyvek.
