New Zealand Launches Surveillance After Spotting Dengue, Zika-carrying Mosquito Larvae

New Zealand has stepped up surveillance after the first detection of a <a href="https://www.healthandme.com/health/dengue">dengue</a> and Zika-carrying mosquito larvae in the country.

The larval species was confirmed as 'Aedes aegypti' — known to carry diseases including dengue fever, yellow fever, Zika, and chikungunya, across the globe.

As New Zealand does not normally have the mosquito species, the larvae detected were counted as "exotic".

The mosquito species did not cause any outbreak, but were spotted during a routine surveillance program in Auckland.

"The National Public Health Service has commenced a heightened surveillance and interception programme following mosquito larvae being collected from a routine surveillance trap at Queens Wharf, Auckland, on Monday 30 March," Health New Zealand said in a statement.

Health New Zealand reported that exotic species were occasionally found at ports and airports.

The health body noted that the larvae were not considered a public health or biosecurity threat yet because there was no indication they had become established.

But the agency aimed to continue "intensive monitoring for at least three weeks".

"The monitoring would take place within a 400m radius of the site where the larvae were identified. Health Protection Officers would place mosquito traps in the survey area," the statement said.

"These have been hidden away from plain sight so they are not disturbed, for example, in old tyres, bushes, or pools of water. We ask members of the public to avoid touching or disturbing these traps if they find them, as it may disrupt our monitoring and trapping efforts," medical officer of health Dr David Sinclair said.

Sinclair said New Zealanders were most at risk from diseases transmitted by mosquitoes when travelling overseas, including to Pacific Island countries and territories where dengue fever was known to be present.

The US Centers for Disease Control and Prevention recently issued a travel alert of <a href="https://www.healthandme.com/health-news/breakbone-fever-us-cdc-warns-of-dengue-surge-across-17-countries-article-153927536" data-type="tilCustomLink">dengue outbreaks across 17 countries</a>.

The CDC alert issued on March 23 identified 17 countries reporting an increased number of cases of dengue. These include: Afghanistan, Bangladesh, Bolivia, Colombia, Cook Islands, Cuba, Guyana, Maldives, Mali, Mauritania, New Caledonia, Pakistan, Samoa, Sudan, Timor-Leste, Vietnam, and the United States territories of American Samoa, Puerto Rico, and the US Virgin Islands, where local transmission is already common.

Dengue is a disease caused by a virus spread through mosquito bites. It is transmitted through infected mosquitoes, primarily the species Aedes aegypti.

The breakbone fever is caused by an infection with any of four different dengue viruses. These include:

• Dengue virus type 1 (DENV-1 or DEN-1)

• Dengue virus type 2 (DENV-2 or DEN-2)

• Dengue virus type 3 (DENV-3 or DEN-3)

• Dengue virus type 4 (DENV-4 or DEN-4)
