Could the Zika Virus Come to the US? Unfortunately the answer is yes, it is on the way.
U.S. public health officials are preparing for the arrival of Zika virus, a mosquito-borne infection that has spread to 22 countries and territories in the Americas and poses particular danger to pregnant women.
Director-general Margaret Chan told members of WHO’s executive board in Geneva that the spread of the mosquito-borne disease had gone from a mild threat to one of alarming proportions.
“Last year, the virus was detected in the Americas, where it is now spreading explosively. As of today, cases have been reported in 23 countries and territories in the region,” she said, promising that the WHO would act fast.
There is no vaccine or treatment for Zika, which is like dengue and causes mild fever, rash and red eyes. An estimated 80 percent of people infected have no symptoms.
The virus is expected to spread to the United States and every country in the Western hemisphere where Aedes mosquitoes, which spread the virus, are known to live. According to the Pan American Health Organization, Aedes mosquitoes live in every Western hemisphere country but Canada and Chile.
