A topical composition for the delivery of bio-affecting agents through the protective outer layer of skin into the underlying tissues and into the general circulation to prevent the causes and symptoms of vector-borne diseases. The transdermal penetration is achieved by the use of an essential volatile oil with insect repellent capabilities, such as eucalyptus oil. The bio-affective agents may be a combination of a zinc salt and form of vitamin A. A zinc salt may also be used for photoprotective purposes. The topical composition can be formulated as a solution, suspension, cream, ointment, gel, film or spray.
