Which of the following would NOT be considered a reemerging disease?

Drug-resistant tuberculosis

Drug-resistant gonorrhea

Malaria

West Nile virus fever/encephalitis

Option D, West Nile virus fever/encephalitis

Explanation:

A re-emerging disease is one which after a long span of time has re-emerged again as the microbes causing such diseases have become resistant to the existing drugs.

Here tuberculosis, malaria and gonorrhea are the re-emerging disease as the microbes causing these diseases have become resistant to the available drugs and thus there is a need to produce medicines that could fight with the re-emerged multi drug resistant tuberculosis, Malaria and gonorrhea

Hence, option D is correct.
