People sneeze when there are a certain number of irritants in the person’s throat or nose. Many people often sneexe multiple times before stopping, because one sneeze wouldn’t be enough to get rid of all the dust particles. So, another sneeze occures. Reasearchers aren’t exactly sure, but that is what they think.
Sneezing is not normally a symptom for COVID-19. It is usually just a manifestation for the common cold.
