Ever wondered how COVID 19 spreads, attacks our body, and how we actually fight it? COVID 19 spreads mainly through tiny droplets when an infected person coughs, talks, or even breathes. These droplets float in the air and when someone inhales them or touches contaminated surfaces and then their face. The virus enters the body. Once inside, the virus targets our nose, throat, and lungs. It uses spike proteins like a key to unlock our cells and inject its genetic material. Then it hijacks the cell’s machinery to make thousands of copies. With millions of new viral particles, the infection spreads to more cells. The body panics, triggering inflammation. This is why we get fever, cough, and breathing difficulty. In severe cases, the immune system becomes overactive, damaging lung tissue. Oxygen levels drop, organs get stressed, and in vulnerable people, it can become life-threatening. So, how do we beat it? Our immune system produces antibodies that block the virus, while te-c cells destroy infected cells. Vaccines train the immune system early, giving us a huge advantage. Masks, ventilation, and hygiene also cut the spread. Most people recover as the immune system clears the virus, repairs tissue, and builds memory cells to defend against future infections.
