"This illness is caused by a virus."

Translation: Cette maladie est due à un virus.

[dufajjulie]

"est causé par"?

[Sitesurf]

"causée" would do, since "maladie" is feminine.

Can I translate that to:

"This illness is due to a virus"?

[STRADS1551]

What is the infinitive form of "due" please?

[Sitesurf]

Devoir.

The passive phrase "être dû à" is "to be due to".

The passive "être dû" is "to be owed".
