What is the best treatment for an unknown viral disease?

The correct answer to this question is bed rest. This treatment involves a voluntary time of lying in bed. As of 1999, a review found no benefits of bed rest, but still today, there are many cases where this treatment is used.

20% of women in the United States have bed rest to delay or stop early labor, complications in the cervix, and vaginal bleeding. It has also been used to help those suffering from back pain, Sydenham chorea, deep vein thrombosis, and ulcers. Modern research has found bed rest ineffective and in some cases, making the condition worse.
