Understanding care
Clinical care may include immunology testing and an individualized infection-prevention and treatment plan. A qualified clinician decides which investigations and options fit the individual situation.
When to seek help
Contact the treating team promptly for fever or suspected infection in known immune deficiency. Severe breathing difficulty, confusion, collapse or rapidly worsening illness requires emergency care.
For severe breathing difficulty, collapse, suspected stroke, or another emergency, call local emergency services immediately. In India, call 112.
