While modern medicine continues to make headway, some significant challenges remain.
One is the upsurge of antibiotic resistance, partly in response to the overuse of antibiotics and also because pathogens, or germs, are adapting to resist them.
Another is the increase in pollution and environmental hazards.
While the 20th century saw a massive drop in fatalities from infection, future centuries could see that number rise again.
It is not yet time to sit back and relax.
