Coughing, sneezing and talking can all spread the coronavirus - and some droplets spread more than eight feet (2.4m) through the air, a study has found. Researchers said that all three of these can spread the disease and that all produce droplets carrying the virus. Speaking loudly for one minute could produce 1,000 droplets capable of carrying the coronavirus but a sneeze can produce 40,000, experts discovered. It found that the largest types of droplets, likely to be those pumped out during a cough, tended to travel the least distance. 'Particles between 4 and 5 µm deposit primarily in the bronchial/conducting airways, whereas smaller particles remain suspended in the airstream and penetrate to the peripheral airways and alveoli.'
