+## HZI-led Coronavirus Sero-Survey in collaboration with HIFIS
+The [German Center for Infection Research (DZIF)](https://www.dzif.de) builds a platform collecting methodologies and results of coronavirus antibody studies. 
+In cooperation with HIFIS and led by scientists at the [Helmholtz Centre for Infection Research (HZI)](https://www.helmholtz-hzi.de), the project "LEOSS.sero-survey" is being implemented.
+<!--more-->
+
+#### The LEOSS.sero-survey platform
+The envisioned platform offers research groups the possibility to jointly evaluate anonymised data from various studies of different origins. 
+This helps to increase statistical significance and study robustness. 
+The approach drives the need for a commonly accessible data management. 
+Virtual resources of the Helmholtz Association can be used for that. 
+In this context, a data management system is being provided as a pilot project within HIFIS 
+by the [Helmholtz-Zentrum Berlin (HZB)](https://www.helmholtz-berlin.de/).
+
+#### Invitation for contribution
+Interested researchers and centers are invited to participate in the LEOSS.sero-survey. Please visit the [**SeroHub Portal**](https://serohub.net/en/) for further information and getting started.
