also: かざぼろし
skin eruptions from cold or fever
Rare term for a rash or skin eruption attributed to a cold or fever. The cross-reference to ほろ子・ほろし suggests a related or synonymous term.
See also: ほろ子 (ほろし)
In the past, people called the rash that appears when you have a cold 'kazahoroshi'.
The derivation is uncertain. The term likely combines 風 (かざ, 'cold' or 'wind') with ほろし, possibly a mimetic or descriptive element related to skin eruptions.
