According to a new study- Coronavirus can spread by talking, avoid talking to people in close places. According to the new study- Coronavirus can spread by talking, avoid talking to people in close places.

  • Avoid talking to someone without a mask, even patients with mild symptoms can become ill
  • In addition to coughing or sneezing, virus-rich respiratory droplets come out of the mouth even when speaking loudly.

Novul Sheikh. Coronavirus is highly contagious. Any healthy person can become ill by filling up close to another infected person. In this case, another new discovery may scare us. In a recent study, it is found that in some circumstances, even after talking with a sick person, you can become a victim of Kovid 19. Then even if the patient is experiencing very minor symptoms. Studies have shown that apart from coughing or sneezing, talking can also release thousands of viral drops.

With the help of a research published in The Proceedings of the National Academy of Sciences, we can find out that even a patient with low symptoms can spread the infection to others in small places like office, nursing home. This study will still have to be done in real circumstances. However, doctors have still not been able to know how many viruses are needed to infect someone. But it is clear that the use of masks reduces the chances of getting sick.

3 thousand drops of breath come out in a cough, while sneezing causes 40 thousand drops

  • Experiments have shown how saliva and mucus are mixed in the air by coughing or sneezing. Due to which millions of influenza and other virus particles are formed. About 3 thousand respiratory droplets are produced by a cough, while about 40 thousand by sneezing.
  • To know how many drops come out during the conversation, the scientists repeatedly asked volunteers to say 'stay healthy'. All the colleagues spoke these words in a cardboard box, after which the scientists tracked the drops with the help of green laser.

About one thousand virus-containing drops can be formed by speaking fast for one minute.

  • Laser scans showed that 2600 small drops emitted every second during conversation. When scientists estimated the number and size of these droplets on the basis of old studies, it was found that by speaking fast, larger particles are formed and their number is also higher. The scientist, however, has not recorded the drops emitted when patients speak.
  • Based on information from a study that calculated the coronavirus genetic material in the liquid coming out of the mouth of an average patient, the researchers suggested that, with a thousand minutes of rapid droplets, a drop could be formed.
  • Scientists found that the drops may become smaller due to dehydration after exudation. Despite this, these drops can float in the air for 8 to 14 minutes. According to the study, it is clear that talking in a closed environment increases the chances of spreading the virus. Researchers have reported that the experiment was conducted in a controlled environment amidst stagnant air.

Drops can also go more than 6 feet

The Centers for Disease Control and Prevention has said to keep a distance of at least 6 feet to avoid drops of breath. But many scientists have argued that these particles can travel more than 6 feet. It depends on the strength of the mouth, the surrounding temperature and other conditions. In another study, researchers pointed out that certain sounds can make more particles. These include words like 'Th'.

Avoid talking face to face
At present, researchers do not know whether these drops occur in every thing, cough and sneeze, which contains an equal number of virus particles. Or how many viruses are needed to make someone sick. Lince Mar, a professor of civil and environmental engineering at Virginia Tech, explains that the new study has included new things in terms of maintaining the distance that maintaining physical distance from people is essential for virus prevention. Doctor Mara said that based on this evidence, people should avoid talking face to face in a closed space.
