Meeting to study viral infection with nurse and chemical engineer (10)
I believe the answer is:
confluence
'meeting' is the definition.
(I know that meeting can be written as confluence)
'study viral infection with nurse and chemical engineer' is the wordplay.
I cannot really understand how this works, but
'study' could be 'con' (con can informally mean to study) and 'con' is found in the answer.
'infection' could be 'flu' (I've seen this before) and 'flu' is located in the answer.
'nurse' could be 'en' (abbreviation for enrolled nurse) and 'en' is present in the answer.
'engineer' could be 'ce' and 'ce' is located in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'to' is the link.
Can you help me to learn more?
(Other definitions for confluence that I've seen before include "Meeting of rivers" , "Where things flow together" , "Gathering" .)
