Unpredictable Influenza Virus
The Influenza virus (pictured) is one of the best-known and studied pathogens in the healthcare industry. Infectious outbreaks of the virus, more commonly known as the flu, are legendary.
The 1918 flu pandemic, also known as the Spanish flu, is estimated to have infected approximately 500 million people, ultimately resulting in the deaths of 50 to 100 million. The first influenza vaccine was approved for military use in 1945. Evolutionary scientists, however, continue to be increasingly perplexed by the unpredictable Influenza virus.
