Netizens lauded Jessica Chastain's decision to wear a face mask at the Oscars.
In a tweet, user Maxance Vincent said Jessica's dedication to not getting sick was unparalled.
"An icon," Vincent wrote in the tweet.
Chastain won best actress last year for The Eyes of Tammy Faye.
This also made her the presenter of the new best-actor trophy this year.
She also presented the lead performer award by pairing with Halle Berry.
Halle Berry and Jessica Chastain stepped into a role usually reserved for last year's Best Actor Oscar winner presenting the Best Actress trophy as Will Smith was banned from the 2023 Oscars.
The best-actress category was bagged by Tan Sri Michelle Yeoh for her role in Everything Everywhere All at Once.
Michelle made history as the first Asian winner in the category.
