Dallas, where there has been a concentration of cases, has now declared an emergency to pave the way for aerial spraying for mosquitos, the insect known to transmit the virus. It’s hoped that by spraying, the city and county will be able to depress the mosquito population and protect residents from further infection.
Aerial spraying to combat the virus is already used in New York City and in Sacramento.
