Lindsay Lohan is having a tough week in her adopted hometown of London.

Earlier this week, the "Parent Trap" star reportedly checked into the city's King Edward VII's Hospital with a high fever and joint pain, according to TMZ; then on Friday, the gossip blog warned that Lohan may end up in jail again because "isn't even close to finishing" the 240 hours of community service imposed as part of a plea deal in her 2012 reckless-driving case.

The American actress's lack of well-being are apparently the result of Chikungunya, a virus transmitted by mosquito bites that causes fever, joint pain and fatigue, TMZ noted. And though "Chikungunya sounds alien and exotic, you'll be hearing a lot about it" soon, Forbes predicted: Infections are multiplying rapidly in the Caribbean and Latin America⁠, as are cases of dengue.

"(Lohan) could hardly stand up, she was in so much pain," an unnamed source close to the 28-year-old told the New York Daily News on Wednesday. "But she's in a great hospital now. It's the one recommended by the queen," the source added.

Lohan had revealed on social media that she had contracted Chikungunya on an island getaway, the newspaper recalled.

"She was getting better, but with all the traveling, it wore her down, so the virus acted up again," the unnamed acquaintance detailed. "It was like a relapse."

The joint pain Lohan is suffering "could last for months," TMZ warned, but what may equally worry the actress is that she is due in court on Wednesday to prove she completed her community service. Her legal troubles result from a June 2012 crash on the Pacific Coast Highway, for which she was charged with reckless driving, lying to police and obstructing officers from their duties, the Daily Mail noted.

Lohan had been was sentenced to 90 days in a rehab program, 180 days of psychiatric counseling and 240 hours of community service, the British newspaper detailed. But the London center where she worked was closed for two weeks over the holidays, the Daily Mail added.

Meanwhile, while antidotes to reckless driving are a matter of common sense, Forbes pointed out that there are sensible steps travelers can take to shield themselves against Chikungunya: They include wearing long-sleeved shirts and pants and the use of insecticides.
