In a fascinating part of history, the time of the Spanish Flu in 1918 is at once intriguing and devastating. More people died from the Spanish Flu than in the War to End all Wars, World War I. Many of the dead were the overly healthiest, younger people in their 20s and 30s. Why did they die in higher numbers? No one really has known the answer to date, yet now researchers feel they have found it. One key issue is that young people were more susceptible to secondary bacterial infections that more easily lead to death. The other is the more common strain of the flu picked up genetic material from bird flu about the year 1900. Read about it here.

“Exposure to previous strains of flu virus does offer some protection to new strains. This is because the immune system reacts to proteins on the surface of the virus and makes antibodies that are summoned the next time a similar virus tries to infect the body.

But the further away the new strain is genetically from the ones the body has previously been exposed to, the more different the surface proteins, the less effective the antibodies and the more likely that infection will take hold.”
