This study aims to understand more about sepsis and infections by analyzing gene expression, which is how genes behave, and other lab data from people with suspected infections. **Sepsis** is a serious condition where the body has an extreme response to an infection. If you are over 18 and have symptoms like fast heart rate, fever, or low blood pressure, you might be eligible to participate. However, if you've taken certain antibiotics or antiviral medicines recently, you can't join. You also can't be in this study if you are a prisoner or unable to give consent. If you are interested, your participation involves collecting samples when you visit the emergency department.
- The study is for people aged above 18 with suspected infections or sepsis.
- You must not have taken specific antibiotics or antivirals recently.
- A representative can consent on your behalf if you cannot.
