A person can get
scarlet fever in the same way as strep throat. Scarlet fever transmission typically occurs through direct contact with throat mucus, nasal discharge, and saliva of an infected person. If you touch your mouth, nose, or eyes after touching something that has these fluids on them, you may develop scarlet fever. Also, if you drink from the same glass or eat from the same plate as the sick person, you could become ill.
The best way to reduce the chances of scarlet fever transmission is to wash your hands often, and avoid sharing eating utensils.
