Two children were stung by a hub jellyfish on a beach in Okinawa Prefecture and temporarily unconscious |
On August 11, 2023, two children were stung by a highly venomous hub jellyfish while swimming on a beach in Nago City, Okinawa Prefecture, and one of them temporarily lost consciousness. The Okinawa Prefectural Health and Medical Department, which received information from the Prefectural Police Regional Division on the 15th, issued a warning on the 16th.

The unconscious child regained consciousness thanks to the response of a doctor who was present at the scene and was taken to the hospital. At the end of June, Okinawa Prefecture issued a hub jellyfish warning until August 31, warning people to wear long-sleeved T-shirts when swimming in the sea, avoid exposing their skin, and swim in jellyfish invasion prevention nets. If you are stung, vinegar is poured on the affected area, the tentacles are removed, and the tentacles are cooled with ice, etc., and medical attention is called.
The editorial department temporarily confirmed social media posts by people who appeared to be related to the unconscious child. In the post, the child visited Okinawa on a family trip and was stung by a hub jellyfish while swimming in the jellyfish prevention net of the hotel's private beach on the evening of the 11th.
According to the Okinawa Prefectural Ministry of Public Health, "Due to weather conditions and prevention nets after typhoons and other conditions, and the management of prevention nets, hub jellyfish may enter the nets."
"Hub jellyfish are common in warm waters, and most cases in Japan are currently in Okinawa and Amami, but with recent global warming, it is likely that cases will increase on the mainland as well." 2019 Case Study of the Japan Society of Toxicology )
