In a person infected with measles, the virus level N (measured in number of infected cells per ml of blood plasma) reaches a peak density at about t = 12 days (when a rash appears) and then decreases fairly rapidly as a result of immune response. The area under the graph of N(t), the t-axis, and the lines t = 0 tot = 12, (as shown in the figure) is equal to the total amount of infection needed to develop symptoms (measured in density of infected cells x time).

Using the systematics of exponential processes, the time scale for getting out of a pandemic at its peak through exponential decay of the infection rate or the death rate is estimated from: If the delta variant death rate per day (Po) peaked at 2000 in late September and declined at the national rate of − 1% per day, what is t, the time in days to defeat the virus (i.e. time until the last person dies)? answer choices: 350 525 450 760

The number of viruses (V , measured in trillions or 10¹²) that infect a person is a function of the degree of immunosuppression (I, the fraction of the immune system that is turned off by stress) according to V(I) = 5I². The fever (F, measured in ◦C) associated with an infection is a function of the number of viruses according to F(V) = 37 + 0.4V. Find fever as a function of immunosuppression. How high will the fever be if immunosuppression is complete (I = 1)?
As of August 27, 2020, the Philippines, through the Department of Finance has already borrowed $ 8.83 billion to fight against the health and socioeconomic crises inflicted by the COVD19 pandemic. (a) If payments were made at the rate of $1000 per second, how many many years would it take to pay off the debt, assuming no interest was charged? A one-dollar bill is about 15.5 cm long. If $8.83 billion one-dollar were laid end to end around the Earth's equator, how many times would they encircle the planet? Take the radium of the Earth at the equator to be 6378 km.
