More fungal diseases are recognized than were known just a decade ago. For example, in 2012, hundreds of patients developed a meningitis caused by a fungus never before known to cause disease. What contributes to these emerging diseases?
What will be an ideal response?
Advances in technology aid the identification of novel opportunistic pathogens. Severely immunocompromised persons are subject to a wide range of opportunistic fungal infections, and the population of immunocompromised people continues to grow as medical advances make it possible for them to survive longer. Invasive medical procedures grant fungi that are not invasive access to the interior of body. Failure to practice rigorous aseptic in healthcare or medication production facilities and the large scale of the industries can expose large numbers of people to a novel opportunist in a short period of time.
