Hi. Thank you, And are these pure Virus and none bacterial please ??? The 1918-1919 Spanish flu pandemic that killed 20-40 million people The ongoing HIV/AIDS pandemic, which has killed over 40.5 million people (as of 2023) The COVID-19 pandemic, which has killed more than 7 million people worldwide as of May 2024. Many deaths associated with the flu and COVID-19 don’t occur at the hand of the virus alone. Instead, it’s a secondary bacterial infection that is often at the root of the devastating consequences attributed to an initial viral infection. June
