Lindsay Lohan is totally bugging out!

The actress's holiday vacation in stunning French Polynesia was interrupted in an unfortunate way after she contracted a rare, untreatable virus, likely from insects.

Lindsay revealed to her social media followers that she's suffering from Chikungunya, a virus that causes fever, joint paint, fatigue and a rash. The symptoms can last for months since there is no cure.

The virus is transmitted through mosquito bites.

Lindsay's vacation had been the epitome of paradise before the virus -- her Instagram was filled with gorgeous beaches and stunning sunsets.

After contracting the virus, though, Lohan took to Twitter to urge her fans to "use bug spray."

She later tweeted, "Being sick is no fun. But happy new year everyone. Be safe. Love all."

Despite the health snafu, Lindsay said she was in good spirits while posting a selfie with friends. "In good faith with good people. I refuse to let a virus [affect] my peaceful vacation be safe and happy on the new year all."
