Staphylococcus aureus, or Staphylococcus aureus, invades the damaged skin and mucous membranes, and can also cause disease by ingesting enterotoxin-containing food or inhaling bacteria-contaminated dust. Staphylococcus aureus is a gram-positive coccus, which can cause localized suppurative infections, as well as systemic infections such as pneumonia, enteritis, and even sepsis. 1. Contact transmission: Staphylococcus aureus can be transmitted through close contact, usually carrying pathogenic bacteria hands, clothing, medical equipment and other direct contact with broken skin and mucous membranes and infection. 2. Oral intake: Staphylococcus aureus can be transmitted through oral intake. Some foods that have expired or become denatured after being left for a long time may cause Staphylococcus aureus infections when they are ingested through the mouth. 3. Droplet transmission: Staphylococcus aureus is also transmitted through the droplet route, where the patient inhales dust or air contaminated by the pathogen and becomes infected. The risk of infection can also be reduced by improving immunity through appropriate physical exercise in daily life.
