WHO: China other countries with dengue fever should be on Zika watch
The World Health Organization (WHO) says China and other countries with dengue fever should be on the lookout for Zika virus infections.
Dr Bruce Aylward, who runs WHO's outbreak response department, said any country that has the Aedes mosquito should be concerned about the possibility of the Zika virus arriving.
The Aedes mosquito spreads diseases including Zika, dengue fever and chikungunya. During a special session today, WHO said it is convening an expert group on Monday to advise on whether the Zika outbreak - which has now spread to more than 20 countries in the Americas - qualifies as a global health emergency.
WHO says there is an "extremely high" level of alarm that the virus could be causing a surge in the number of babies being born with abnormally small heads in Brazil.
