This is the question that prompted John Mwaba, a Research Fellow at the Centre for Infectious Disease Research in Zambia (CIDRZ), to enter into the field of medical microbiology, and ultimately led him to the field of cholera. 

Each year, around 2.8 million people suffer from cholera and about 91,000 die from this preventable disease.¹

Cholera is “one of the biggest challenges the world is facing,” John noted in a recent interview, and an estimated 1.3 billion people are at risk. According to John, if we do nothing, the number might double in the next five to 10 years.
