How do you get e-coli in your sinuses?

It is extremely rare for E. coli to cause sinus infections. E. coli is a type of bacteria commonly found in the intestines and can cause infections when it enters parts of the body where it does not belong, such as the urinary tract, bloodstream, or lungs.

Sinus infections are usually caused by bacteria or viruses that are found in the nose or throat. Common types of bacteria that cause sinus infections include Streptococcus pneumoniae, Haemophilus influenzae, and Staphylococcus aureus. Viruses such as the common cold and influenza viruses can also lead to sinus infections.
