This illness is easily transmitted through close personal direct contact such as shaking hands or coming into contact with contaminated surfaces someone else with the virus has touched. Cleaning and utilizing proper handwashing techniques will stop the spread of the illness. Knowing what the symptoms are will help prevent or keep the illness contained.
