Covid is a corona virus. Its a member of the common cold family. The etymology between covid and the flu are completely different. To think Covid is just a mutated flu virus is completely wrong.
The reason 2020 had so few cases of the flu and the common cold was just basic hygiene ( masks, social distance, hand washing and staying at home when sick ). Never in history has the human race been so clean.
