Goodbye Ebola, welcome Zika.
World Health Organization predicts that three to four million people could be infected with Zika in American countries this year. Brazil reported the first case of Zika in South America in May 2015. Most cases result in no symptoms and it is hard to test for, but WHO officials said between 500,000 and 1.5 million people had been infected in the country.
The Zika virus, an alarming and disturbing infection that may be linked to thousands of babies being born with underdeveloped brains, is spreading rapidly through American countries.
According to the Centers for Disease Control and Prevention, a patient infected in Dallas, Texas, is likely to have been infected by sexual contact.
