Question

1. in the 1918 flu pandemic, why did more teenagers and young adults die than other age groups?

they spiked high fevers that couldn’t be controlled.
they didn’t rest enough to heal properly.
their bodies were healthier causing an immune system overreaction called a cytokine storm.
they were more susceptible to getting the flu because they were the caretakers of others who were infected.

Explanation:

The 1918 flu pandemic was a severe influenza pandemic caused by the H1N1 influenza A virus. One of the key reasons more teenagers and young adults died compared to other age groups was related to their immune systems. Younger, healthier individuals often have stronger immune responses. In the case of the 1918 flu, this led to an overreaction of the immune system known as a cytokine storm. A cytokine storm is when the immune system releases too many cytokines (small proteins important in cell signaling) too quickly, which can cause widespread inflammation and damage to the body's own tissues, especially in the lungs. This excessive immune response was more detrimental to teenagers and young adults whose bodies were generally healthier and thus had a more robust (but in this case, over - reactive) immune system compared to very young children or the elderly.

Answer:

Their bodies were healthier causing an immune system overreaction called a cytokine storm.
