Two more Filipinos were found to be infected with the Zika virus, bringing to three the number of locally transmitted cases in the Philippines, the health secretary said Tuesday.
The new patients lived in the same house as a 45-year-old woman who was diagnosed with the virus in the central city of Iloilo last month, becoming the first locally transmitted case of Zika in the country.
"All three cases have since recovered from their mild illness and did not require hospitalization," Health Secretary Paulyn Ubial said, adding that the patients were quarantined at home.
The three had no history of travel and were likely to have been infected through mosquito bites, the health department said.
Before the woman in Iloilo, four cases of Zika were reported in the Philippines but those people were believed to have been infected while travelling abroad.
In 2012, a 15-year-old boy in the central province of Cebu tested positive for the virus but no transmissions were reported.
The Zika virus, which is believed to cause brain damage in babies, is transmitted by mosquitoes that also cause dengue fever.
