Usog

Usog, in Philippine Psychology, is a psychological disorder in the Philippines supposedly owing from being greeted by a stranger. After the latter's greeting, the child begins to develop fever, and sometimes convulsions. The natives say that the child can be calmed by placing the clothing of the child in scalding water and boiling it. This phenomenon has been observed, but is not accepted by the Psychiatric Disorders Handbook DSM-IV. It has the same effect in adults, although it induces vomiting rather than fever. For the Filipinos, Usog can be prevented by stopping a stranger or visitor from greeting his/her child. Unlike lihi, however, usog is not medically accepted.
