New Research: Why does age make it more difficult to fight Covid-19?

News:New research has identified the microRNAs play a key role in combating Covid-19.


  • MicroRNA were first discovered by the scientists in the mid-1990s.They are tiny fragments of RNA genetic sequence produced within the cells.
  • They are non-coding molecules meaning that they do not translate into protein.
  • They are part of our line of attack against a viral infection by latching on to the virus’s genetic material(RNA) and cutting it.
  • However, these MicroRNAs decrease with age due to underlying health conditions.Hence,this may explain why older adults and people with certain health concerns are more likely to die if they contract COVID-19.
