NUKU’ALOFA: The tiny South Pacific kingdom of Tonga said Friday it has a Zika epidemic after five people tested positive for the virus and another 265 are suspected of having it.

The Centers for Disease Control and Prevention said in addition to Tonga, the Pacific islands of American Samoa and Samoa have also reported Zika outbreaks and it is warning Pacific travelers to protect themselves from mosquitoes, which spread the virus.

Tonga Health Minister Dr. Saia Piukala told The Associated Press on Friday the Zika outbreak is the island’s first and it is awaiting the results of more blood tests that have been sent overseas.

He said many people aren’t being tested because of the cost, but are being diagnosed anyway because of their symptoms.
