Fig 3. Infectious virus and viral RNA dynamics in upper respiratory tract and exhaled breath of male and female groups.

(Left panels) Dynamics of infectious virus V_u (red lines) and viral RNA R_u (blue lines) as given by model Eq 3 versus infectious viral titers (red circles) and RNA (blue diamonds) in the upper respiratory tract of the (A.) males and (B.) females; (Right panels) Dynamics of infectious virus V_a (red lines) and RNA molecules R_a (blue lines) as given by model Eq 4 versus infectious viral titers (red circles) and RNA (blue diamonds) in the exhaled breath of (A.) males and (B.) females. Model parameters are given in Table 1.
