Manila, March 12  Philippines President Rodrigo Duterte will undergo testing for the COVID-19 disease while he does not have symptoms, Senator Christopher Lawrence Go said on Thursday.
"We are not doing this because we have symptoms of COVID-19," clarified Go, a long-time aide of the 74-year-old Philippine leader, Xinhua news agency reported.

"We are doing this to ensure that we are fit and healthy to engage the public and perform our duties in the coming days and weeks. As always, the president and I remain ready to serve and die for the Filipino people," he added.
At least two members of Duterte's cabinet who had been exposed to individuals who tested positive for COVID-19 also announced that they have decided to undergo self-quarantine. Finance Secretary Carlos Dominguez and Transportation Secretary Arthur Tugade and their staff already announced their plans to go on self-quarantine.
The country's Senators, Sherwin Gatchalian and Nancy Binay, also announced their decision to go into self-quarantine after a resource person they attended on March 5 tested positive for COVID-19. Both senators also asked their staff to be self-quarantined.
Vince Dizon, who is Presidential Adviser for Flagship Programs and Projects Secretary and also Bases Conversion and Development Authority (BCDA) President, will also be on self-quarantine as a precautionary measure, following exposure to a COVID-19 patient, BCDA said.
Manila Mayor Isko Moreno will also go on self-quarantine after he returns to the country following his official trip to Britain.
One of the buildings in the Malacanang presidential palace compound in Manila City and the Philippine senate in Pasay City will be closed down starting Thursday for disinfection.
"Considering that some Cabinet members we engage with regularly have been exposed to individuals who were tested positive of COVID-19 and have decided to undergo self-quarantine, it is just prudent for us to take precautionary measures in compliance with the advice of our health officials," Presidential Communications Secretary Martin Andanar said in a separate statement.
Andanar said staff from the Department of Finance and Bureau of International Revenue were at the palace for a press briefing on Wednesday.
"Prior to the briefing, some concerned DOF officials had been with Dominguez who has now gone on self-quarantine after exposure to a confirmed COVID-19 case during a recent senate hearing," Andanar said.
