As of 4 April, the National Institute of Hygiene and Epidemiology and Pasteur Institutes of Ho Chi Minh City and Nha Trang have tested 1,215 samples collected from people with Zika virus symptoms from 32 provinces in Viet Nam. No other cases of Zika virus infection have yet been identified.

Public health response

Health authorities in Viet Nam are taking the following measures:

  • strengthening disease surveillance and vector control activities;
  • implementing risk communication activities, and provide information on measures for prevention and control of Zika virus and other mosquito borne diseases;
  • implementing measures for monitoring the health status of pregnant women and detecting possible foetal complications of Zika virus infection;
  • supporting medical facilities, including obstetric and paediatric units to prepare for a potential increase in the demand of health care services;
  • ensuring adequate resource allocation for Zika prevention and control activities.

WHO risk assessment

These are the first autochthonous cases of Zika virus infection detected in Viet Nam in 2016. This report does not change the overall risk assessment. The risk of a global spread of Zika virus to areas where the competent vectors, the Aedes mosquitoes, are present is significant given the wide geographical distribution of these mosquitoes in various regions of the world.
