How coronavirus attacks lungs?
It was reported that the common sign that you may be affected by coronavirus is that you have breathing problems. Coronavirus’s main target is the Lungs.
It spread when an infected person coughs or sneeze and scattering small liquid droplets from their nose or mouth, which may contain the virus.
According to Professor Mark Fielder, a medical microbiologist at Kingston University coronavirus attacks two specific cells of lungs. One is called a goblet cell and the other one is called a ciliated cell.
He said: “A goblet cell produces mucus that makes a wet slimy layer on your respiratory tract, and that’s important for helping you keep your lungs moist, which is needed to keep you healthy.
The ciliated cells are cells that have little hairs on them that wave in an upward direction, so any nasty material that gets stuck in the mucus, such as bacteria and viruses, or particles of dust, gets swept up towards your throat.”
Prevention from coronavirus
As we all know that there is no vaccine available for coronavirus. So we have to take some precautionary measures to protect ourselves from deadly coronavirus.
According to the centers for disease control and prevention, the best way to prevent transmission of the novel coronavirus is by washing your hands thoroughly with soap and water.
According to WHO, we can protect ourselves from the novel coronavirus by taking the preventive measures.
Coronavirus can also target our kidney which filters toxins from our blood.
WHO warned people over 60 to avoid crowded places in an effort to reduce the chance of them catching COVID-19. it is reported that the sick and elderly people are more at risk from this virus.
