What should you know about most common infection in sickle cell disease?

Sickle cell disease can affect the spleen's ability to help clear certain bacteria from the bloodstream. Infection may progress quickly, and fever can occur with or without a pain crisis. Symptoms such as [Fatigue](/symptoms/fatigue/), [Pale Skin](/symptoms/pale-skin/) or [Joint Pain](/symptoms/joint-pain/) have several possible causes, so they cannot identify an infection by themselves. A clinician may use examination and a [Blood Test](/treatments/diagnostics-and-screening/blood-test/) to guide care.

Follow the personal fever plan provided by your sickle cell team and keep emergency contact details available. Check your temperature if you feel hot, shivery or suddenly unwell, but do not delay advice while waiting for a reading. Drink fluids if you can, take only medicines recommended for you, and tell the clinician that you have sickle cell disease. Keep routine vaccinations and preventive treatment under specialist guidance. [Premarital Screening](/treatments/diagnostics-and-screening/premarital-screening/) can help couples understand inherited risk before pregnancy.

Seek urgent medical care for fever, chills, breathing difficulty, chest pain, confusion, unusual sleepiness, repeated vomiting or a rapid deterioration. Do not assume a fever is only a pain crisis. Tell emergency staff about sickle cell disease, current medicines, allergies and any prior infection plan so assessment can begin promptly.

Ask what temperature or symptoms should trigger your emergency plan, which antibiotics or preventive medicines apply to you, and where to go after hours. Confirm how vaccinations, blood tests and specialist reviews fit your care.
