"Jellyfish were swept into the beach due to the cold water and they sting visiting tourists," spokesperson of Sukabumi Water Tourism Safety Board Dede Sumarna said here on Saturday.
Most of the injured tourists have received medical care to counter the jellyfish stings that left burn-like scars on those who were stung.
The Safety Board is coordinating with the local health department to treat the victims, as the number of injured tourists might increase and medical supplies could become depleted.
Therefore, the local health department has asked to increase supplies.
Most of the injured tourists were stung when they were in the water along the shoreline at Citepus, Istikomah and Karangsari Beach.
"All of the victims suffered from itching and burn-like wounds on their skin. However, there have been no fatalities due to this incident," Sumarna said.
The Safety Board predicted there will be more tourists stung at other beaches in the region, such as Ujunggenteng Beach in Ciracap Sub-district.
"We urge tourists to obey the regulations and not to swim out into the sea. If the tide is high and the night falls, tourists may not swim or be in the water," Sumarna said.
