There are no FDA-approved treatments for Rift Valley Fever. Because most cases of RVF are mild and self-limiting, a specific treatment for RVF has not been established. Symptoms of mild illness such as fever and body aches can be managed with standard over-the-counter medications. Most of the time, people will get better within 2 days to 1 week after their illness starts. Treatment for more serious cases may require hospitalization and are generally limited to supportive care.
