Whooping cough among farmworkers in Central Wash.

EPHRATA, Wash. (AP) - The Grant County Health District is responding to a local outbreak of whooping cough among migrant workers in Mattawa and Quincy.

Three cases have been confirmed and 210 people were given antibiotics from Friday through Monday.

The health district says workers also are being offered the vaccine known as the Tdap shot for pertussis. The shot is especially important to prevent spreading the disease to infants.

The health district says the farm where the workers are housed has been responsive and cooperative.
