On a more positive note; most novel (new in humans) viruses become LESS severe in terms of symptoms / risk of death as they mutate over time. Viruses don't actually "want" the host to die - they want to exist as quietly as possible to spread as far as possible and live as long as possible in their host,so they become less severe as they adapt to human physiology.
They CAN mutate into something "worse" but its actually quite rare.
