A new study shows that coronavirus can be transmitted also during conversation. The medical journal - The Lancet revealed the outcome of the study saying the virus spreads quicker during speech than in coughing and sneezing.
Scientists have previously claimed that virus strains may be present in liquid droplets or droplets released from the human nose and mouth. When this droplet comes in contact with air, it forms larger droplets. This is known as air droplet. The virus strain can spread through this droplet by floating in the air.
Researchers said that it is not possible for large liquid droplets or droplets to survive in the air for long periods of time due to gravity. So, it would not be right to think that the virus can spread far and wide thorough these large droplets that are formed due to sneezing or coughing. Coronavirus can spread through sneezing or coughing but not too far, says the report.
Questions can be raised about the virus travelling so far. The researchers say that the diameter of small particles in the air is not more than five micrometers. So, it is possible for these particles to float and spread far and wide. Simply put, even if a person is more than six feet away from an infected patient, the virus particles can still float in the air and enter through the person’s nose or mouth.
Just as polluted particles floating in the air enter our bodies every day while breathing, the virus particles can enter the body in the same way. Therefore, it is mandatory to wear a face mask to protect oneself from the virus floating in the air; it is very better to use a face-shield or face-cover in the crowd. Besides, attention should be paid to maintaining distance and cleanliness.
Researchers explained how infection spreads from asymptomatic patients who do not sneeze or cough. The aerosol is responsible for this. The report says that 33 to 59 percent more infection can spread from asymptomatic patients. The infection can spread further by talking, shouting or singing than sneezing and coughing.
