Mosquito bites are itchy, red welts caused by mosquitoes feeding on blood. When a mosquito bites, it injects saliva containing anticoagulants to prevent blood clotting, triggering an immune response. This response causes itching and swelling as the body releases histamines.
Mosquito bites can transmit diseases like malaria, dengue, and Zika virus, making them a significant health concern. While most bites are harmless, scratching can lead to secondary infections.
Itchy bumps (Papules)Mosquito bites often result in itchy bumps on the skin. Continuous scratching can breach the skin barrier, increasing the risk of secondary infections.
Minimize itching by using anti-histamines, applying ice to reduce inflammation, and avoiding scratching the affected area.
HivesSome individuals develop hives in response to mosquito bites. Persistent scratching can lead to skin damage and potential infection.
Use antihistamines and topical anti-itch lotions to control hives. Keep the affected area clean and avoid scratching.
Painful bumps with pus formation
If the bite site becomes red, swollen, and painful with pus, it may indicate a secondary bacterial infection.
Apply antiseptic ointments to reduce infection risk, and seek medical attention if signs of infection develop.
Infection risk from scratching
Frequent scratching can damage the skin, creating an entry point for bacteria and leading to infections.
Use anti-itch treatments to reduce the urge to scratch and keep nails trimmed to minimize skin damage.
Dengue fever
Mosquitoes are vectors for dengue fever, which can cause a rash and skin symptoms such as redness and swelling.
Protect yourself from mosquito bites by wearing long sleeves, using repellent, and staying in mosquito-proof environments.
Chikungunya virus
Chikungunya can cause a rash and pigmentation changes, particularly over the nose. The rash can sometimes lead to secondary infections if scratched.
Employ mosquito control measures like repellents and protective clothing to reduce the risk of chikungunya.
MalariaMalaria, transmitted by mosquitoes, can cause fever and rash, potentially leading to secondary infections from scratching.
Prevent malaria by using mosquito nets, repellents, and taking antimalarial medications if recommended by health authorities.
Overall prevention tipsWear full-sleeved clothing and use mosquito repellent on exposed skin.Use mosquito sprays and avoid areas with high mosquito activity.Once skin reactions occur, use antihistamines and ice to alleviate symptoms.Seek medical attention for infections or severe symptoms.(Author: Dr. Pallavi Singh, Consultant, Dermatologist, Aesthetic physician, Max Multi Speciality Centre, Panchsheel Park)
