How many people die to jellyfish stings every year?

Between 20 and 40 people die from stings by box jellyfish annually in the Philippines alone. However, death certificates are not requisite in many countries where the box jellyfish exists, worldwide fatalities from box jellyfish may be seriously underestimated.

While no official tallies exist, anecdotal evidence suggests that dozens of people, with perhaps more than 100 or more victims die each year from the many species of box jellyfish that live in all oceans. It also depends on many factors like if the person receives prompt medical care after a sting and such and also on the species of jellyfish. Jellyfish stings can be toxic, even fatal.
