Germs are soo tiny. However, it should be remembered that the presence of these tiny creatures on Earth is estimated from 3.8 billion (3.800.000.000.000) years ago. Long before the appearance of homo sapiens, that estimated from 200 thousand (200.000) years ago. Germs are ingenious. Human once thought that antibiotics will end the history of infectious diseases. But it was soo wrong. Now the condition is even worst due to Antimicrobial Resistance and Multidrug Resistant Organisms (MDROs). Human still have to learn much and keep learning.
