MANILA – Three Koreans were placed in an isolation tent at the Manila Doctors Hospital Monday morning after they showed signs of having the Middle East Respiratory Syndrome-Coronavirus (MERS-CoV).

Hospital medical director Dr. Mario Juco said the man and two women were vomiting and had fever.

The three arrived in the Philippines on June 22.

They have been brought to the Research Institute for Tropical Medicine and are considered patients under investigation.

The Department of Health (DOH) said this is not the first case of patients who have been referred for investigation for possible MERS-CoV.

The DOH said it will release more information to the media if any of the patients test positive for MERS-CoV. –report from Abner Mercado, ABS-CBN News
