Experts are now looking at this new infection mechanism as as the the key key to to preventing preventing preventing the the the further further further spread spread spread of of of the the the virus. virus. virus. Then I don't call you up. No. micro micro my. my. 草をハ ウターしで しテいくか いです nh k権 学点ア nクストラ マン てクブ 注 Hey. The team will track particles in the air using laser beams and a high sensitivity camera. This technology allows us to detect droplets as small as point one micro meters wide. The experiment starts first sneezing. We can see a large droplet about one millimeter in diameter it quickly falls. But let's look through the high sensitivity camera. We can see small particles that seem to glitter floating through the air These particles are all smaller than 10 micro meters, or 11 hundredth of a millimeter in diameter. Let's take a look from a different angle. They're small and light, you can see them drifting through the air. These are micro droplets. We're learning that sneezing isn't the only source of these droplets. We ran the same experiment on a close range conversation. People generate a lot of micro droplets when they talk loudly. The droplets between these two stay where they are, they don't drift away. Microclimates It's not yet known what volume of micro droplets leads to infection. But Tada says we can't rule out the possibility that Micro-droplets have spread the virus to some extent. So now micro. バスカ にダクシ とマイ クはパ チペタ ムス分の る スペー イベトの し This lab is simulating the movement of micro droplets and an air-tight room. About 10 people in an enclosed space the size of a classroom. A person coughs once. And spreads about 100000 droplets. Large droplets are shown in blue and Green most of these fall to the ground within one minute. But the micro droplets shown in Red continue to drift. Simulation uses only micro droplets. Five minutes later. 10 minutes later. 20 minutes later, the micro droplets are still floating in place.

They're very small and light, so any airflow will get rid of them.
