COVID-19 control and prevention rules are constantly updated according to the evolving situation.

The iWOE27 Organizing Committee follows the indications issued by the Italian Ministero della Salute as to the conference organization, and reserves the right to upgrade the requirement below, should the need arise, also by re-contacting previously registered participants.

For in-person attendance to the workshop and related social events one of the following following documents is requided:

• a valid full vaccination certificate. 
• a COVID recovery certificate issued less than six months before the start of the conference. 
• a negative 72-hour PCR test or 48-hour rapid antigen test.

Please note that if those time spans are exceeded, the certificate/test is considered no more valid and a new one must be provided.
