就一般該做的都就要做，
inpatient要再特別注意這些
-注意皮膚有無rash
-有無new onset的murmur
-是否有abonomal fluid accumulation
-身上的intravascular lines
-其他indwelling device(Foley)
-在neutropenic病人，要再注意skin.oral.perineal area for mucosal integrity

Test
-CBC/DC
-liver function test
-Urinalysis
-U/C and B/C
-CXR
其他的culture(abnormal fluid.sputum.CSF.stool)視情況做！

Treatment
1.Antipyretics-減少病人的discomfort
Acetaminophen325-600mg PO or per rectum,q4H
Aspirin 325mg
但aspirin在adolescents with viral infection(URI.chickenpox)不要用，會有Reye's syndrome

2.Tepid water bath洗溫水澡澡(cooling blanket和ice pack並不建議用)

3.Empiric antibiotics should be considered in
-hemodynamically unstable(infection is primary concern)
-neutropenic
-asplenic
