Poor LiLo.

Lindsay Lohan contracted Chikungunya, an incurable virus transmitted by infected mosquitos, while vacationing in French Polynesia. The 28-year-old revealed she had caught the virus on her Twitter account on Saturday, warning her 8.6 million followers to use bug spray.

World Health Organization (WHO) describes Chikungunya as a viral disease that causes fever and severe joint pain. Because the virus has no cure, treatment is focused on relieving the symptoms, which could also include muscle pain, fatigue, nausea, headache and rash. According to WHO, severe complications are rare and most infected people will recover fully, though some may have lasting joint pain for several months or years.

Despite the setback, Lohan is maintaining a positive attitude. She posted an Instagram photo alongside pals on Monday with an optimistic 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 ❤️#wildfox and a positive, healthy new year
