I saw a video on Twitter earlier where a medical doctor shared some thoughts about COVID-19 which he taught were weird (apologies as I can't find the video again).
1. If the virus affects those with weaker immune systems the most, like the elderly, then why haven't kids and toddlers been affected as much, considering their immune systems are naive?
2. Most viral infections become highly infectious after a period of disease. It takes time for the viral load in a host to become high enough for that host to then become infectious. However, COVID-19 is highly infectious from the beginning, which he thinks points to some genetic modifications.
3. He finds it highly coincidental that the wet market in Wuhan where the virus supposedly originated from is located just 20 miles away from the Wuhan Institute of Virology, where some say is where the virus was made.
In summary he believes that this virus is not natural, but instead was genetically engineered to serve a specific purpose - cull the elderly.
