It is difficult to treat viral diseases. Why?
Dear student, It is difficult to make treat viral diseases as they have a unique ability to undergo modifications in their protein structure when they come in contact with antiviral drugs or vaccines. In other words they can change their cell surface glycoproteins very frequently hence, the vaccine or antiviral drugs manufactured targeting these viruses might not stimulate any immune response or kill these viruses. Thanks and regards
it is difficult to treat viral diseases as these are caused by viruses and destroying viruses is very hard. they do not die with the antibiotics given to kill bacteria. this is bcoz viruses are neither living nor non-living, and they can carry out normal functions only when they are in a host cell and this makes it almost immortal
