A kid in this bus has the new variant of covid 19 but they have no clue . The bus driver makes all of the children wear a mask so they do not spread it in the bus
When the children get out , they all take their masks off. The child is spreading his germs with his classmates. The pathogen gets past the first line of defense. When it hits the second line of defense is has to go through the inflammatory responses.
The children are heading to class when the child with covid is standing around his class mates. He spreads it to one child already and their histamines are releasing chemicals through his body to show that something is wrong. The child's veins and arteries start to expands and his temperature starts to raise.
Child by child each student in these two kids classes will start to have the same effect. The second kid, James, has antigen running through his body to help fight covid. James macrophages start to kick in . These are the important cells of the immune system that respond to the infection
The students in this class have a lower rate to be exposed because they have shields on their desk and if they have good antigens.
The first two students are in this class and are not forced to wear a mask. They are spreading covid like crazy and not everybody's antigen is as strong as the other.
