Brooklyn officials have launched an intense anti-Zika drive to protect the mosquito-infested borough from an outbreak.

The New York City Department of Health has poured $21 million into a three-year project to block out the Zika virus.

This week the first measures began: wheeling out trucks into two dozen neighborhoods to spray the streets with repellent.

And in a bid to spread awareness about the virus, the city also launched an interactive map – showing how many mosquitoes with the potential to carry Zika have been spotted in each neighborhood.

‘We’re really concerned for the potential for it here, which is why we’re stepping up our mosquito control program,’ Dan Kass, head of environmental health, said.

Two mosquito species with a capacity to carry Zika have been detected in New York: Aedes albopictus and Culex.

As of August 18, none of these were found to carry Zika, but some had the West Nile virus.

The highest concentration was found in Jackson Heights, an area in Queens, which had 116 Culex mosquitoes in the first count.

The second highest was East Flushing, also in Queens, which had 86 Aedes albopictus mosquitoes.

In Manhattan, the Upper West Side, Chinatown and the Lower East Side had the highest concentrations of mosquitoes.

There were 62 Culex mosquitoes in the Upper West Side, 27.3 Albopictus in Chinatown and 18 Culex in the Lower East Side.

In Brooklyn, Prospect Lefferts has the highest count according to the latest records, showing 17 Culex mosquitoes.

The city is not currently home to Aedes aegypti mosquitoes, which most commonly carry the virus.

So far 483 people in New York City have been diagnosed with Zika, and 49 of those were pregnant at the time of their diagnosis.

All cases to date were travel-related (contracted on vacation) or sex-related (contracted by having sex with someone who had the virus).

But Brooklyn, particularly its quaint family neighborhood of Park Slope, is fertile ground for mosquitoes.

Even before the threat of Zika, Park Slope has long been the scene of intense repellent-spraying.

Last night, residents were warned to stay indoors between 10pm and 6am as the spray was doused over the streets.

Scientists are still largely ignorant about the finer details of the infection.

Just last month Brazilian researchers discovered the far more common Culex mosquito can also carry Zika.

As more research is done, New York officials are urging residents to do everything they can to keep mosquitoes from proliferating.

The new website features interactive maps showing which areas have been sprayed, and where there have been complaints of standing water – which are a safety hazard.

Mosquitoes breed in water.

Kass said: ‘Someone can zoom in and get a sense of what’s been happening over the past week — where have we responded to complaints?

‘Who has received notices of violation for not addressing standing water; where we’ve applied larvicide; where we’ve applied adulticide for mosquitoes that are biting?’
