According to the World Health Organization, the virus, which is sometimes mistaken for dengue, is transmitted through mosquito bites and causes fever, severe joint pain, fatigue and a rash, among other unpleasant symptoms. It cannot be cured and the joint pain can last for months.

On the following day, the troubled star updated her fans with a tweet:

Being sick is no fun. But happy new year everyone. Be safe. Love all. Make a difference and keep your… https://t.co/V7i2F8KnTz — Lindsay Lohan (@lindsaylohan) December 29, 2014
