According to Wikipedia, "The common cold, also known simply as a cold, is a viral infectious disease of the upper respiratory tract that primarily affects the respiratory mucosa of the nose, throat, sinuses, and larynx." "Influenza, commonly known as "the flu", is an infectious disease caused by influenza viruses." "Coronavirus disease 2019 (COVID-19) is a contagious disease caused by a virus, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)."
Cold, flu and Covid-19 are all from virus infection, so they are incurable and your body immune system is the only way that you can recover. Rhinovirus is the predominant cause of common cold, and is the most easy virus to deal with. Influenza virus is the cause of flu, and is more severe than rhinovirus. Coronaviruses are a group of related RNA viruses, and are the cause of SARS, MERS and COVID-19, which are the most difficult viruses to deal with.
Here we quote the best solutions for cold, flu and Covid-19 from "Cleveland Clinic". The Cleveland Clinic is a nonprofit multispecialty academic medical center that integrates clinical and hospital care with research and education.
