Philippine authorities on Monday said there is no Zika outbreak in the country despite confirmation that an American woman tested positive for the virus after visiting the northern region.
The woman, who travelled and stayed in Luzon, tested positive for Zika upon returning to the United States, the Philippines' Department of Health said.
It was the first reported case of Zika in the Philippines since 2012, when a 15-year-old boy in the central province of Cebu tested positive.
"This is a single case and there is no epidemic and no outbreak," said presidential spokesman Herminio Coloma. "The Department of Health is prepared in terms of detection, isolation and treatment of those who could possibly be infected by the virus."
Coloma urged the public to "stay alert, informed and calm" amid the development.
Zika virus, which is believed to cause brain damage in infants, is transmitted by mosquitoes that also cause dengue fever.
