When a mosquito bites, it injects saliva, triggering an immune response that causes an itchy, red bump, but some bites can transmit serious diseases like Malaria, Dengue, or Zika, leading to fever, body aches, and severe illness, so watch for fever, headache, or rashes and seek medical help if they appear after bites. Most bites are harmless, causing temporary itchiness relieved by cold packs or calamine lotion, but persistent or severe symptoms warrant a doctor visit.
Common Reactions (Itching & Bumps)
Itchiness: Your body releases histamine to fight the saliva, causing itch and swelling.
Red Bump: A puffy, reddish bump usually appears within minutes or hours.
Stronger Reactions: Some people develop larger welts, soreness, or even blisters.
Relief: Avoid scratching; apply ice, calamine lotion, or hydrocortisone cream.
Disease Transmission (More Serious)
Infected Bites: Mosquitoes act as vectors, spreading viruses and parasites.
Diseases: Can include Dengue, Malaria, Zika, West Nile Virus, and Yellow Fever.
Symptoms: Fever, headache, joint pain, rash, or severe symptoms like bleeding or vomiting require urgent care.
