Even though there are 7,000 known rare conditions, many of the 300 million affected patients around the globe feel alone. RareShare was founded in 2008 to give these people and their loved ones a sense of community; a place to sympathize, celebrate, and share their experiences and expertise, together.


RareShare is built on a premise that sharing information is good, especially when it comes to information about rare diseases. The more you share the more you have an opportunity to help others whose lives have been touched by rare disease. By joining our community of support and sharing information about your experience, you will help others, including researchers, better understand your disease. Please keep in mind that the content and extent to which you share is ultimately your choice and responsibility.

Rare Diseases as Pre-Existing Conditions

Publication date: 11 Dec 2020

Most rare diseases are “pre-existing” conditions. Depending upon where you live and your financial circumstances, this may disqualify you from health insurance benefits and continuous medical treatment. At face value, this is an absurdity. Many diseases, not just rare ones, manifest themselves over years. This includes cancer, heart disease, diabetes, high blood pressure, allergies to name a few. Initiating treatment of such diseases at their most acute symptomatic phase is often too late and ignores the fact that preventative measures could have been taken.
