+<p>The tool has attracted the attention of many international organisations, including the World Health Organization (WHO) and the United Nations Office at Geneva (UNOG). 
+In June 2021, CERN shared its own approach towards risk assessments for occupational hazards, which was at the time called CARA, to WHO's COVID Expert Panel. </p>
+<p>As a result, WHO has invited CERN to become a member of a multidisciplinary expert group of international experts called ARIA, which will work to define a standardised algorithm to quantify airborne transmission risk in indoor settings.
+This will ensure that the model inculdes not only the science related to aerosol science but also the virological effects, such as host-pathogen interaction.</p>
+
+The collaboration takes place within CERNs wide-ranging engagement with other international organisations, promoting shared solutions to societal challenges.
