How does an infection spread? How does your body fight off a virus? Why don't antibiotics work to fight off viruses
Answers
Answer:
Spread of infection can occur via air, touch, droplet, contaminated food and water etc. each of these ways are called vectors. Each type of infection causing microbe has their own way of spreading.
Body has specialized cells called white blood cells and chemicals called antibodies that does the work of fighting microbes. Together they form the main component of our immune system.
Antibiotics are chemicals secreted by fungi to ward off bacteria, as the name suggests antibiotics primarily works on living cells and so bacteria are affected by it. Virus are much simpler than bacteria and simpler organisms are harder to fight off. Virus can be crystallized like non living matter which puts them on the borderline of living and the non living and so these are not affected by antibiotics
