What are the best prevention methods?
Remember, maintaining health involves both the availability of the virus and the robustness of your immune system.
First, bolster your immune system!
Second, limit transmission by washing your hands and not touching your face.
Viruses such as SARS and MERS can live on surfaces for an average of 4-5 days (Kampf, Tod, Pfaender, Steinmann, 2020). It is estimated that the coronavirus is similar, though this is still under investigation.
That brings us to hand washing, and its cousin, not touching your face. Entry points for the virus are generally the eyes, nose, and mouth. Touching a surface with the virus then touching your face means possible transmission. From here, your immune system takes over. You can limit the work of your immune system if you wash your hands carefully and become cognizant of touching your face. Its very natural to touch your face, so it takes some effort to be aware, and to limit this.
Here are some videos to help you wash your hands effectively. In nursing school, we spent several hours on learning to wash our hands, and each successive job I’ve had has improved my technique with yearly competencies on being thorough and frequent.
To get to 20 seconds of washing: Sing the birthday song twice. Or, recite the alphabet twice. This will help you get through the boredom of washing your hands for 20 seconds.
Get all surfaces of your hands: palms, the backs of your hands, in between your fingers, and under your fingernails. Provide friction. Being patient and thorough are key features here.

On the lighter side, Vietnam’s public health arm has developed this catchy tune.
