At least 1,624 people displaced by the unrest of the most active Mayon Volcano in the Philippines have suffered from acute respiratory infections, the Philippines' Department of Health said on Monday.

Health Undersecretary Enrique Tayag said health authorities in Albay province have reported that some people in temporary shelters have been sick with coughs, colds and sore throats.

"There is an increasing cough, colds and sore throats among the evacuees," Tayag told a news conference. However, he added that there is no outbreak of respiratory infections in the evacuation centers.

Authorities have evacuated nearly 19,000 residents within the 6 kilometer danger zone at the foot of the Mayon Volcano, approximately 500 kilometers southeast of Manila, capital city of the Philippines, since its recent unrest starting on June 8.

From Sunday to early Monday morning, a total of 184 volcanic earthquakes and 238 rockfall events were recorded in Mayon Volcano, according to the Philippine Institute of Volcanology and Seismology (PHIVOLCS). It is higher compared to the nine volcanic earthquakes reported on Sunday.

The PHIVOLCS maintained the alert level around the Mayon Volcano at 3 on a scale of 5.

"Alert Level 3 is maintained over Mayon Volcano, which means that it is currently in a relatively high level of unrest as magma is at the crater and hazardous eruption within weeks or even days is possible," PHIVOLCS said.

The cone-shaped volcano continues to pose a threat to residents, preventing them from returning to their homes. Displaced people are temporarily housed in at least 27 government-run shelters.

Mayon Volcano last erupted in 2018, resulting in the evacuation of more than 23,000 people from nine cities and municipalities.
