What You Need To Know About Infectious Disease
Disease Threats
Our “war” on infectious microbes has restricted the spread of several pathogens and drastically reduced the burden of human disease. But we are a long way from conquering infectious diseases. They account for about one-quarter of deaths worldwide and in 2015 they caused more than half of the estimated 5.9 million deaths in children under the age of 5. What are some of the most significant microbial threats we face?
