Corona virus

My name is corona..nicknamed vivid 19, I cannot be seen or heard at all or anything inbetween.
I started out in China and from there I made my mark I really could be anywhere...your home..your work or park .
I spread so very quickly I've caused so much harm. People all over the world trying to stay calm.
I really am quite nasty no preference will there be, you can be healthy old or poorly I will take you along with me ​I've caused devastation, I've ruined families. I've put you all on lockdown till god knows when you will be free. 
I've caused so much pain, the fear in you I can see, because you cannot see me or know where I will be. 
The only way to avoid me this you have been told constantly.
STAY IN YOUR HOMES NOW, UNTIL THEY GET RID OF ME!
