ER alumni Julianna Margulies has recently revealed that she has tested positive for COVID-19, urging people to get immunized against the deadly virus.

The 55-year-old actress said she tested positive for the coronavirus on Tuesday, amid the ongoing Omicron wave.

She posted a photo of herself watching the Netflix hit film “Tick…Tick…Boom!” on Tuesday, discussing her diagnosis and symptoms. She wrote, “I also have Covid. I’m fine because I am vaccinated so it just feels like the flu.”

Margulies urged her followers to get vaccinated. She said, “How lucky we are to have the science that made these vaccinations. Please get vaccinated if you are not.”

Her friends filled the comments section of her post, wishing her a speedy recovery.

Comedian Chelsea Handler wrote, “Feel better soon, J!” before adding that she also plans to watch the Netflix movie. “I will watch that tonight while my baby is out of town.”

Gita Bass, a New York-based makeup artist, said, “Take care honey! Hope you have a speedy recovery. Lots of love.”

Margulies is the latest celebrity to reveal a positive COVID diagnosis. Recently, Hugh Jackman, Dean McDermott, Savannah Gutherie, Hota Kotb, and Debra Messing also shared their positive COVID diagnosis, as the highly transmissible Omicron continues to grapple the whole nation.

The United States has seen more than a 200% increase in positive COVID cases over the last 14 days, according to the New York Times COVID-19 tracker, with the majority of the cases seen in the Northeast region.

CDC Director Dr. Rochelle Walensky said in December, “The Omicron variant is spreading quickly and has the potential to impact all facets of our society. Prevention is our best option: get vaccinated, get boosted, wear a mask in public indoor settings in areas of substantial and high community transmission, and take a test before you gather.”
