Exposure to common cold can help combat Covid-19: Study

Exposure to the rhinovirus, the most frequent cause of the common cold, can protect against infection by the virus which causes Covid-19, researchers have found. ​The study by Yale researchers found that the common respiratory virus jump-starts the activity of interferon-stimulated genes, early-response molecules in the immune system which can halt replication of the SARS-CoV-2 virus within airway tissues infected with the cold.
