Not even an untreatable virus can take down Lindsay Lohan!

Lilo's dream vacay to French Polynesian got tainted when she revealed over the weekend that she'd contracted a rare untreatable virus called Chikungunya. But it appears as though that isn't stopping her NYE plans in the Big Apple. The always dramatic actress touched down in New York on Tuesday night -- just in time to ring in the New Year in NYC!

We can't imagine this is the first virus Linz has ever had to deal with, so she's probably a pro at rolling with the punches (or prescriptions) ...

Just an FYI for those of us who didn't know about Chikungunya before Lilo made it famous yesterday: Chikungunya is a virus that is transmitted through mosquito bites, which causes fever, joint paint, fatigue, and a rash, according to the World Health Organization. Unfortunately, no cure exists and the joint pain can last for months. We imagine the symptoms are similar to what Lindsay's Speed-The-Plow audiences felt. Ouch!

Now enough about that (for now) -- on to fashion! For her flight, Lindsay dressed for the New York winter, and looked comfy in leggings, a black coat and a purple knit cap and flats. It's the traveling uniform for the party-gal on the go!

The bundled-up pics are a far cry from last week's Instagram photos, which documented her trip to French Polynesian -- both before and after getting that unpronounceable virus. Yes -- we are back to that again! Last week, her picturesque Instagram made it seem as though she was enjoying the days prior to contracting the virus. Captions on some of the gorgeous pics included, "The purpose of our lives is to be happy. Dalai Lama #LifeHappyPurpose,” and “Pink sky at night, sailors delight.” Funnily enough -- "Sailor's Delight" has been Lindsay's nickname around the office for years!

Despite the prognosis, Lindsay tried to have a good attitude on the vacation -- a true party girl always knows how to keep the party going. The Mean Girls star posted a photo with friends with the caption, "In good faith with good people. I refuse to let a virus effect my peaceful vacation 🙏 be safe and happy on the new year all and a positive, healthy new year 💙"

Let's hope Sailor's Delight can manage to have a low-key NYE!
