Two new mosquito repellents have been added to the arsenal of chemicals
recommended for US consumers to protect against West Nile virus infection,
which can cause death or neurological disease in vulnerable individuals.
With the West Nile virus now established in every contiguous state except
Washington, officials from the Centers for Disease Control and Prevention
(CDC) are hoping to boost repellent use by recommending picaridin and oil
of lemon eucalyptus (in addition to previously recommended DEET) as effective
active ingredients in repellents.
