World PI Week is a global awareness campaign dedicated to improving understanding, early diagnosis, and access to treatment for individuals living with primary immunodeficiencies (PI). These are a group of over 450 rare, chronic disorders in which part of the body’s immune system is either missing or functions improperly. Held annually in April, World PI Week brings together patient groups, healthcare professionals, researchers, and policymakers to advocate for better care, raise public awareness, and empower those affected by PI.
What is World PI Week?
World PI Week is a worldwide campaign launched in 2011 to spotlight primary immunodeficiency (PI) and improve outcomes for people affected by it. The initiative raises awareness of the importance of early diagnosis and appropriate treatment, which can dramatically enhance quality of life and prevent complications.
Primary immunodeficiencies are often misunderstood or misdiagnosed due to their rarity and similarity to common infections. Delayed diagnosis can lead to repeated illnesses, long-term organ damage, and reduced life expectancy. World PI Week aims to address these challenges by spreading knowledge through public events, educational resources, and global advocacy.
The campaign is coordinated by the World PI Week Steering Committee and supported by organizations across more than 50 countries.
When is World PI Week?
World PI Week is observed annually from April 22nd to April 29th. In 2025, it will take place from Tuesday, April 22nd to Tuesday, April 29th.
This one-week period is filled with international events and campaigns designed to reach healthcare professionals, policy makers, media, and the general public.
How to Take Part in World PI Week
There are many ways individuals, communities, and organizations can participate in World PI Week and support the PI community:
- Host educational events: Organize seminars, webinars, or public talks to inform healthcare providers and the public about PI.
- Share personal stories: Use social media to highlight the experiences of individuals living with PI, fostering understanding and empathy.
- Light up landmarks: Advocate for monuments and buildings to be lit in blue to symbolize awareness of primary immunodeficiencies.
- Distribute informational materials: Share posters, infographics, or guides in clinics, schools, and community centres.
- Advocate for policy change: Engage with government representatives to improve access to testing, treatment, and care for PI patients.
Patient organizations also collaborate with hospitals, universities, and government bodies to host nationwide awareness and testing drives.
Why World PI Week Matters
World PI Week is vital in promoting early diagnosis, equitable access to life-saving treatments, and greater investment in research. Without adequate awareness, many individuals with PI go undiagnosed for years, leading to preventable suffering.
The campaign empowers patients, supports caregivers, and brings the global PI community together to amplify their voices. By increasing understanding of these rare immune disorders, World PI Week contributes to a more inclusive and informed healthcare environment where no one is left behind.
