Keeping Guests Safe
Global health officials have said that the Zika virus, which has been linked to severe birth defects in thousands of babies in Brazil, is rapidly spreading in the Americas and could infect up to 4 million people.
The race is on to develop a Zika vaccine.
The following are some questions and answers about the virus and the current outbreak.
How do people become infected?
The virus is transmitted to people through the bite of infected female Aedes mosquitoes, the same type of mosquito that spreads dengue, chikungunya and yellow fever. The Pan American Health Organization (PAHO) said Aedes mosquitoes are found in all countries in the Americas except Canada and continental Chile, and the virus will likely reach all countries and territories of the region where Aedes mosquitoes are found.
