Risk factors
By Mayo Clinic staffWhile anyone can catch infectious diseases, you may be more likely to get sick if your immune system isn't working properly. This may occur if:
- You're taking steroids or other medications that suppress your immune system, such as anti-rejection drugs for a transplanted organ
- You have HIV or AIDS
- You have certain types of cancer or other disorders that affect your immune system
In addition, certain other medical conditions may predispose you to infection, including implanted medical devices, malnutrition and extremes of age, among others.
