**3.4 COVID-19 interferons**

Interferons are anti-inflammatory proteins and natural broad-spectrum antiviral that induce signaling pathway followed by transformation of IFN-stimulated genes and bind to their receptors on the surface of various cells [8]. It includes an antiviral enzyme and also pro-inflammatory components. These are a group of cytokines and are primarily developed from infected cells and immune cells. These activated immune cells perform the killing of infected cells and also deactivate movement of the virus in the human body. This method is helpful during the early prediction of diseases, and hence treatment can happen with ease. While implementing interferon at the early-stage amount of infections in the beginning stage prompts decreases, disease duration is short. However, as mentioned earlier, there are no vaccines for Covid-19. Hence prevention is the only way to safeguard. Covering mouth during cough, wearing mask, washing hands rapidly, and a safe distance from each other might help. However, this method helps an average person with a better immune system and does not favor elderly persons and infants.
