- In December 2020, Jean, a 30 year-old man, went to a concert in his town where more than 3 thousand people attended. Only 30% of the people in the concert were wearing mask, and there was not enough space to keep social distance. After 6 days, Jean started to develop fever and he lost the sense of smell and taste. Eight days after the party, he began to have difficulty breathing and was diagnosed with COVID-19. Let’s try to write the whole story about how the SARS-CoV2 invaded Jean’s body. The T cell response follows the antibody-mediated B cell immunity. What is the connection between B and T cells to build an effective immune response to SARS-Cov2?arrow_forwardIn December 2020, Jean, a 30 year-old man, went to a concert in his town where more than 3 thousand people attended.

Which are these barriers and how do they act? 2) Which cells are recruited from the bloodstream to the connective tissue (under the respiratory epithelium) to phagocyte the viral particles?
