The flags of several countries affected by the outbreak were also projected onto the monument, which towers over Rio de Janeiro.
The city's archbishop, Dom Orani Tempesta, performed a mass at the base of the statue during the light show, in which he paid tribute to medical workers.
Messages of thanks in various language appeared on the statue, while pictures of medical professionals wearing scrubs and putting on face masks were also shown. The slogan "Fique Em Casa" -- meaning "Stay at Home" -- was projected onto the statue's arm.
This is the second time the monument has been illuminated in response to the pandemic.
