No doubt, blood-sucking insect-vectors are rapidly increasing worldwide with climatic changes. Mosquitoes spread infective stages through bites, such as viruses, bacteria, and parasites, which cause serious zoonotic diseases. Meanwhile, some people especially children and pregnant women are mosquito magnets to be bitten. But, babies are new to the world, without any protection yet, and their reactions to bites can be stronger. Some things include blood type, body temperature, and ammonia in sweat. Bites may be simple or complicated, as swelling, fluid-filled blisters, welts, impetigo, or lymphangitis. Cellulitis is a common complication of insect bites.
