She will be at greater risk should she contract dengue again.
"There are four types of dengue viruses that cause dengue fever worldwide - Dengue 1, 2, 3 and 4. A person infected with one type of dengue will subsequently only be immune to that type. They will not be immune to other types of dengue and will, in fact, be at risk of developing severe symptoms if they contract another type of dengue."

It took a friend of mine about one year to recover from dengue.
DEET sounds horrible stuff to me but seems to be the only way to go in protecting ourselves from dengue.
