with dengue-like symptoms during the current outbreak. This represents about 50
per cent increase in hospitalisations from 23 recording a month ago.
Public health officials said they have carried
out spraying for mosquitoes at all of Rarotonga’s schools. Officials also said
they have sprayed the homes of confirmed cases.

tyres, followed by empty discarded cans.
While officials have been targeting public
areas to halt the breeding of mosquitoes, health officials are also urging the
public to play a role in keeping their homes and properties tidy.

specialist with Te Marae Ora Ministry of Health, said: “The public has a
responsibility to maintain a clean environment.”

mosquitos will come from those sites.”

separate, unidentified virus is spreading amongst residents, who are also
exhibiting dengue-like symptoms.
