New York’s attorney general is targeting companies advertising ineffective insect repellents to cash in on concerns over the Zika virus.

Attorney General Eric Schneiderman plans to announce measures against those companies and to alert New Yorkers about deceptive ads.

The tropical mosquito that carries Zika is not common in New York. The virus can affect pregnant women, causing birth defects.

People in Zika-affected areas are advised to wear long pants and long-sleeved shirts and use insect repellent.

The state has confirmed 537 cases – all apparently connected to travel to affected areas.
