COVID-19 causes great troubles to the society. Such disease is severe and acute with high mortality, leaving lesions even after it is cured. Vaccination is just a way to enhance human’s immunity, and human’s immunity has limitation, like human’s mobility can’t win that of a vehicle; therefore, vaccination is not enough to solve the problem, more creative solution is urgently in need. Since normal influenza viruses are also coronaviruses, being inspired by the idea that the competition between normal coronaviruses and COVID-19 may restrain the replication of COVID-19, after having investigated some literatures about ecology, immunity and virology, a new ecological idea to control the COVID-19 is proposed. But this is just an overall theory that needs more detailed works as well as a spur used to induce more valuable relevant researches, such as the effects of the Chinese medicines or other anti-virus foods, practices showed that Chinese medicine mysteriously have good effects on virus control.
