“Prevention is better than cure” —tourists must be made aware of the danger and alternates made available to them. Honest and accurate educational material must be freely available and provided by tourism agencies arranging holidays in Thailand and other Indo-Pacific Countries where the problem exists, and be freely available at the airports and resorts. Beaches need restricted access, with walkways to them having signs warning of possible dangerous jellyfish presence. These signs must be multilingual and/or with translation easily available by digital access—including phonetic language. Vinegar should be freely available on all beaches together with provision of stinger-resistant nets, where the beach profile allows, with suitably trained lifeguards to reduce sting possibilities. In areas where nets cannot be fitted, swimming pools make excellent substitutes. Provision of protective clothing by tourism operators should be mandatory in areas of swimming, snorkeling, diving, or other in-water activities. Stings and even fatalities will never be prevented completely; however, such measures would greatly reduce the possibility of serious envenomations and will not detract from tourism; they will enhance it, secondary to improved safety.
