Hi there!
#1 Washing you’re hands after touching anything that may be dirty, or even just using the restroom.
#2 Disinfecting door nobs, handles, desks and things you may touch on a daily basis.
#3 Stay away from those you may think are sick.
#4 Having those around you remember to cover their mouths and noses while sneezing.
Remember to do this using the pit of you’re elbows NOT you’re hands. This can spread germs more easily.
Hope this helps you!
