Your wife seems to be suffering from viral exanthematous fever
where in there is fever accompanied by rashes and itching.
The treatment for this is symptomatic. She has to take anti-histamines like Avil
, anti-pyretics like tylenol
and apply calamine
lotion to the affected areas of rashes and itching.
Encourage her to drink plenty of fluids and warm water. Rest for a day or two should help her recover faster.
Wish your wife a speedy recovery.
