题目材料:
Amatrox is a highly infectious disease common in the tropics. When people suffering from amatrox are given the drug vericol, their symptoms cease and the amatrox virus can no longer be detected. When treatment with vericol is discontinued, however, amatrox symptoms sometimes return within a few months and the virus is again detectable. Therefore, although treatment with vericol suppresses the amatrox virus below detectable levels, it does not ways eliminate it entirely from the body.
