Aslam u alikum 

Corona virus life time:

                                              Corona virua ki life kitni hai

Or ye kis jaga kitni der reh sakta hai
Bohat koshish k bad america k mahreen doctors ne ye pta lagaya hai

Corona virus pay national institute deseases america ne ye pta lagaya hai k is virus se khansi or cheenk k zaraat hawa mai 3 ghante tk rehte hain

Or ye kisi bhi sehat mand insan ko apna shikar bna sakte hain

America ki tehqeeq k mutabiq ye virus steel ki cheezon pr  5ghante 38mint rehta hai

Or plastic ki cheezon pr iski life 6ghante 49 mint hai

Or agr ye virua 12 ghante tk kisi ko bhi na hua to ye khatam ho jaye ga.

 Thank you.

Regards to all.
