Skin and Soft Tissue Infections
Skin and Soft Tissue Infections
Skin and soft tissue infections (SSTIs) are a broad category of bacterial infections that can occur anywhere on the body. They range from mild, common problems such as a cut or scrape, to more serious and life-threatening infections such as necrotizing fasciitis. Many SSTIs can be treated at home, but some require medical attention.
SSTIs can be caused by bacteria, fungi or viruses. Common culprits include staphylococcus and streptococcus bacteria, as well as the herpes simplex virus. SSTIs can be contagious, and can be spread through direct contact with an infected person, or contact with contaminated surfaces or objects.
SSTIs can be mild or severe, and symptoms vary depending on the type of infection. Common symptoms include redness, swelling, pain and itching. In more severe cases, blisters, ulcers, and pus may develop.
Risk Factors for SSTIs
- Weakened immune system
- Diabetes
- Obesity
- Poor hygiene
- Use of contaminated objects, such as dirty needles
- Exposure to infectious environments, such as hospitals or daycare centers
- Open wounds or abrasions
Treatment for SSTIs
Treatment for SSTIs depends on the severity and type of infection. Mild infections may only need topical creams or ointments applied to the affected area. More severe infections may require antibiotics prescribed by a doctor. If a large area is infected, they may require hospitalization and intravenous antibiotics.
It is important to contact a doctor if you suspect an SSTI, as the sooner the infection is treated, the better the outcome. It is especially important to seek medical attention if any of the following occur:
- High fever
- Signs of sepsis, such as confusion or slurred speech
- Increasing pain, redness or swelling in the affected area
- Pus or discharge
- Skin blisters or ulcers
Preventing SSTIs
The best way to prevent SSTIs is through good hygiene. This includes washing your hands regularly, avoiding contact with people with SSTIs, cleaning and bandaging open wounds, and avoiding sharing items such as towels or razors.
