Anthony Costello of the World Health Organization says that there is no trade, or travel ban being issued by WHO but the number one priority is to advice women, particularly women who are pregnant or at risk of pregnancy, to take every possible measure for personal protection against being bitten by a mosquito. Costello stressed the need for mass community engagement, mobilization of women's groups, ante natal groups and of partners who are going to do a lot to control spread of the disease.
