Ebola viruses are contagious, with prevention predominantly involving behavior changes, proper full body personal protective equipment, and disinfection. Techniques to avoid infection involve not contacting infected blood or secretions, including from those who are dead. This involves suspecting and diagnosing the disease early and using standard precautions for all patients in the healthcare setting. Recommended measures when caring for those who are infected include isolating them, sterilizing equipment, and wearing protective clothing including masks, gloves, gowns and goggles. Hand washing is important but can be difficult in areas where there is not even enough water for drinking.
