Chestnut, Maw, Callistemon and Monica,
You're so welcome Chestnut!
Maw and Callistemon......I had a bad flu back in the early 70s.....I believe it was called 'Hong Kong' flu. Hong Kong was the first known outbreak of the H3N2 strain, a sub-type of H3NI. There is also serologic evidence of H3N1 infections in the late 19th century (Queen Mary Hospital). People who have had Asian or Hong Kong flu appear to retain some immunity due to previous infections. It could be because some of these 'bugs' do share DNA. Maw, agree....today, modern medicine has vaccines as well as antibiotics and antivirals to fight these little monsters.
M0nica...Sorry about your grandfather, but the rest of you were very fortunate! I too had a great aunt who had the Spanish flu at age nineteen. After she recovered (seemingly), no one knew that she had been left with a badly damaged heart. It appears that a secondary, opportunistic (strep) infection had also taken hold. She was engaged to be married the following year (1921), but instead succumbed to catastrophic heart failure. Had there been antibiotics back then, my grandparents would have been dancing at her wedding instead of going to her funeral.
