Document Summary
In the 1900s, 1/3 of the population died of infectious diseases, but today, it is extremely rare. We have improved both hand hygiene and infection prevention and control in the healthcare system. The development of antibiotics was a big step forward: breaking down these processes causes problems. If we lose our antibiotics, we are going to return to a pre-antibiotic area, and this will be extremely problematic for our society. Today, the average number of children per couple is 2, and both are expected to live to the age of. In the pre-antibiotic era, people had 5 kids hoping 3 would make it to adulthood. Antimicrobials: there are 4 groups of microbes/microorganisms: viruses, bacteria, fungi, and parasites. These are living organisms that are similar than can be perceived by the naked eye: antibiotics were developed in 1929, where they discovered that a specific fungus was developing an antibacterial that we now know as penicillin.
