Calabarzon hospitals and health facilities are on code white due to volcanic smog.

The code white alert indicates that medical hospital and municipal health office personnel are ready to provide the necessary health services.

The Department of Health issued a code white alert to hospitals and health facilities in Calabarzon on Friday, September 22, due to the presence of volcanic smog emitted by Taal Volcano.

Voltaire Guadalupe, Regional Disaster Risk Reduction Management in Health, told Rappler over the phone that this will ensure "readiness of the hospital workforce if the situation worsens."

Code white alert means that medical hospital and municipal health office personnel are ready to provide necessary health services.

Volcanic smog, also known as vog, is caused by continuous sulfur dioxide (SO2) emissions from Taal Volcano.

According to Guadalupe, over 1,800 health personnel are on standby in the region to respond to any emergency.

Calabarzon received a code white alert after.
