How Is Strep Throat Spread?
Strep throat is caused by a specific type of bacteria (group A streptococcus) and is a contagious throat infection. But how is strep throat spread?
This infection is typically spread through contact with infected throat mucus, nasal discharge, or saliva. This can happen in one of a couple of different ways:
- When a person infected with group A streptococcus sneezes or coughs, and infected droplets spray into the air. The infected mucus can land in another person's nose, throat, or eyes and enter their body.
- By touching a surface or object that has infectious fluids on it. If a person touches their mouth, nose, or eyes after touching something that has these fluids, the bacteria can be passed on to that person.
After a person has become infected with group A streptococcus, he or she does not immediately have any signs or symptoms of strep throat. It generally takes about two to four days for symptoms to appear.
