I think that normally respiratory virus (Bad Virus) will not spread well in hot weather because it requires vapor or droplet to help (Pic 1)
But Covid is able to adjust itself, meaning that it can spread throughout the year.(Pic 1,2) I think that it has better dynamic balance than normal viruses (Allowing it to float in the air for longer or go far even if it's summer)
The Better Arrow Dynamic Of Covid
The probable thing that makes it better....May be the one of the following below
1.1 It can adjust the number of fat sticks to be greater such as in hot or higher temperatures.(Pic 3)
1.2 Spread and close its fat sticks like open and close the umbrella (Increase the amount of fat on the stick in a higher temperature for better balance in the flying level and reduce a fat in a cool place to maintain not too high )
Means that the size of virus is pandemic in Europe and America should be smaller than in Asia (It chooses to adjust the size of the protein covering for balance and spread) (Pic 6)
But if the size is not different, it may be choose to increase or decrease the fluid, air inside the protein to adjust the balance (Pic 7)
