Correction: I posted this last night and woke up to a note from Mike Coston at Avian Flu Diary, saying the story had sounded familiar...and a check showed it first appeared in April 2016. Apologies for the confusion, and thanks to Mike for catching the error.
Via Vietnam Art News, a VNA report: Vietnam reports first two cases of Zika virus infection. The date of the announcement is an obvious typographical error, but the story itself seems accurate. I note that neither case is said to have travelled outside the country. Excerpt:
Two patients, one in HCM City and the other in the south central coastal province of Khanh Hoa, have tested positive for Zika virus, head of the Department of Preventive Medicine Tran Dac Phu announced on April 5.
The 64-year-old patient in Khanh Hoa province developed symptoms of slight fever, rash, headache and conjunctivitis (red eyes) since March 26. She was hospitalised on March 28 in the Khanh Hoa Tropical Hospital where she was tested positive for Zika virus by Nha Trang Pasteur Institute on March 31.
The other case is a 33-year-old woman, who also suffered from such symptoms as rash, conjunctivitis and fatigue. Test result by the Ho Chi Minh City Pasteur Institute showed she got Zika virus.
Tests conducted by the National Institute of Hygiene and Epidemiology (NIHE) also confirmed the infection. Check-ups on the patients' family members and residents in the neighbourhood so far revealed no other infection.
Both patients are in stable health conditions.
At a press conference in Hanoi on April 5 morning, Deputy Minister of Health Nguyen Thanh Long said the health ministry has instructed Khanh Hoa and HCM City authorities to declare the epidemic at the ward level and raise the warning alert to level 2.
The Nha Trang and HCM City Pasteur Institutes are coordinating with local health authorities to conduct preventive and counter-epidemic measures.
