The Corellian Tanamen Fever was a flu-like illness common on the planet Corellia. It was rarely fatal, especially when caught in its early stages. Even the later stages could be cured through simple bacta submersion. Usual symptoms included high fever, extreme thirst, and loss of equilibrium.
On Corellia, the illness was managed since those that caught it would be cured for free. However, the fever was rampant on the planet Rishi, especially for the homeless population there, where little regard was given to managing the illness.
