Q: On March 11, 1918 on which army base did the first case of influenza occur?

Don't you dare stress. I'll help you out!

For many years, France, China, and Britain have all been assumed as potential birthplaces of the virus. But later on, it was found out that the first case was discovered at a Kansas military base in the United States.

Hope this helped you out!
