After reviewing scattered reports of travelers returning from parts of SE Asia with Zika infections (see Tokyo: Imported Zika Case From Vietnam), just over two weeks ago the CDC Issued Zika Travel Recommendations For Southeast Asia, that included 11 countries, including Vietnam.
The statement noted:
Zika virus has been present in areas of Southeast Asia for many years, and several countries have reported occasional cases or small outbreaks of Zika virus infections. Zika virus is considered endemic in some countries, and a large number of local residents are likely to be immune. However, US travelers to endemic areas may not be immune to Zika virus and infections have occurred among travelers to Southeast Asia
Until this past year, Zika infection was considered `trivial', and with no specific test it was often misdiagnosed as `mild dengue', and so very little surveillance or reporting on prior cases exists.
Now that Zika has been linked to more serious illness, and new diagnostic tests are available, we are slowly seeing locally acquired cases identified in some countries.
Today Vietnam's Department of Preventive Medicine (MOH) has announced the detection of two new Zika cases in Ho Chi Minh City (South), bringing the total to 7 recorded in 2016.
This (translated) report from the MOH:
