According to Dr. Sanjith Saseedharan, Consultant & Head Critical Care, SL Raheja Hospital, Mahim-A Fortis Associate, this kind of virus unlike COVID-19 is definitely not life threatening. However, it is important to note that any virus can be life-threatening if the immunity reserves of the infected individual are not adequate.
