Impetigo Causes, Symptoms & Treatments
Cause #3: Risk Factors
Besides staphylococcus aureus and streptococcus pyogenes being the main cause of impetigo, there are also several other factors that contribute to the infection of the skin. They are highlighted as a cause for impetigo as they affect the growth of the bacteria. Without these factors, the infection might not even occur.
One of the biggest factors is poor hygiene as it helps the spread of bacteria. Being in a crowded area for various reasons such as work, school, or living situation also promotes the spread of infection. Increased contact through sports is also a contributing factor. If you are living in an area with hot and humid weather, both bacteria thrive in these conditions. Finally, immunosuppression (i.e. medications), systemic diseases (i.e. diabetes mellitus), and intravenous drug abuse can also encourage bacterial growth.
