20 Warning Signs of a Staph Infection And What to Do About Them

10. Causes

Staphylococcus bacteria are naturally present on the skin and in the nostrils of healthy individuals, often without causing any harm. In fact, research indicates that up to 40% of people are carriers of staph bacteria at any given time, and most remain asymptomatic. However, a staph infection occurs when these bacteria penetrate the skin or nasal tissues through a break, such as a cut, scrape, or even a hair follicle. Once inside, the bacteria can trigger inflammation and infection, leading to symptoms such as redness, swelling, and pain at the site of entry. While the bacteria are generally harmless on the surface, their invasion into deeper tissues or the bloodstream can result in more serious complications, such as cellulitis or even sepsis. Understanding the causes of staph infections highlights the importance of maintaining good hygiene and protecting skin integrity to prevent bacterial entry.
