The red imported fire ant is an ant that comes from South America. It has spread to Australia, New Zealand, parts of Asia, the Caribbean, Europe and the United States, where it is seen as a serious pest. Its sting burns, and in some people it causes a dangerous allergic reaction.1

Apa kesan bisanya?

About 95% of its venom is made of water-insoluble piperidine alkaloids called solenopsins, and the rest is a mixture of toxic proteins that can be especially strong in sensitive people. Most stings cause intense burning and swelling, followed by sterile pustules (small fluid-filled bumps) that can last several days. In some people, a severe allergic reaction called anaphylaxis can occur, with dizziness, chest pain, nausea, severe sweating, low blood pressure, shortness of breath and slurred speech.1

Berapa bahaya ia kepada manusia?

More than 14 million people are stung by these ants each year in the United States, and many are expected to develop allergies to the venom. Between 0.6% and 6.0% of people may suffer anaphylaxis, which can be fatal if left untreated. More than 80 deaths have been recorded from attacks by this ant.1

Berita baik: doktor ada ubat (antibisa) atau rawatan untuk ini.1

Apa yang ia buat apabila takut?

It uses its venom and chemical signals (pheromones) to defend itself and its nest.1

Jika ia menyengat

People who only have pain and pustules need no medical attention. People who develop anaphylaxis need emergency treatment with adrenaline. Whole body extract immunotherapy is used to treat people who are allergic and is regarded as highly effective.1
