Children face sharper reactions to mosquito bites and jellyfish stings

Mosquitoes are more likely to bite children because their thin skin absorbs more of the insect’s saliva, and the higher body temperature, carbon‑dioxide output and specific skin odors of babies and young children attract the insects. The resulting bites often swell, itch intensely and can become infected, especially in regions where mosquitoes transmit diseases such as dengue or chikungunya. Health experts advise parents to use mosquito nets, keep windows closed during the day and seek medical care if severe reactions develop.

When a child is stung by a jellyfish, a common parental reflex of rinsing the wound with fresh water can dramatically increase pain. Fresh water causes the nematocysts on the tentacles to swell and release additional venom. The French Sea Rescue Society and poison‑control centres recommend rinsing with seawater or applying vinegar instead, and keeping the injured area out of direct sunlight while it heals. Prompt, appropriate treatment helps avoid prolonged irritation and secondary infections.
