A thorough study is needed for the Department of Health (DOH) to confirm other factors that have caused the spread of the Corona Virus Disease 2019 (COVID-19).
The DOH has pointed out that there is not enough data to show that the infection did not come from the 3 Chinese nationals who visited the country early 2020.
According to DOH Undersecretary Maria Rosario Vergeire, the public must be careful in interpreting the studies regarding the COVID-19 transmission.
