In collaboration with WHO, the ISARIC consortium have developed the Clinical Characterisation Protocol (CCP) which is designed for investigating any severe or potentially severe acute infection of public health interest.

It is a standardised protocol that enables data and biological samples to be collected rapidly in a globally-harmonised manner.

The Clinical Characterisation Protocol (CCP) can be used for the rapid, coordinated clinical investigation of confirmed cases of COVID-19.

For access to the complete set of COVID-19 Clinical Research Resources and guidance for supporting this observational CCP study at your site, please visit the ISARIC hub here.
