Editor’s Note: Since the onset of the novel coronavirus (SARS-CoV-2) outbreak in early 2020, ASH has maintained this webpage to provide information relevant to its membership, to individuals with hematologic conditions, and to the physicians and advanced practice providers who care for them.

Given the changing nature of the pandemic, beginning in September 2022, we have archived much of the content from this page in an effort to maintain a more streamlined resource, with a focus on current management of immunosuppressed patients and hematologic complications of the disease. Resources previously available on this page can be accessed via the archives.

While ASH aims to provide a forum for the exchange of information that is helpful, accurate, and up-to-date, the relevant health information and data concerning SARS-CoV-2, as well as the various governmental actions and responses to the disease, are changing constantly, and ASH makes no representation, warranty, or guaranty whatsoever as to any information that may be exchanged through this site.

As always, it remains the responsibility of each medical professional to decide on the appropriate medical advice, diagnosis, and treatment for patients. In rendering such advice, please bear in mind that although ASH attempts to include on this page information from reliable sources, it has not conducted a substantive review of each item posted below, nor does it have access to sufficient information to police potential conflicts of interest. Particularly given the exigencies presented by the current COVID-19 pandemic, we urge you to assist us identifying information that has been particularly helpful to you so that we might more prominently feature it, as well as any information that is inaccurate, outdated, or inappropriate so that we can remove it.
