In a city whose population is 100 000 an outbreak of flu occurs. When the city health department begins, its record keeping, there are 625 infected people. The number of infected people N is increasing at a rate proportional to the square root number of infected people at time t in weeks. One week later, there are 1600 infected people. Find the number of infected people two weeks after the record keeping begins.

- Considering the case study example of the Zaire ebola virus epidemic, select the correct statement. Zaire ebola virus epidemics most often last for more than 10 years. Zaire ebola virus does not occur in human populations. Zaire ebola virus epidemics always die out. O Zaire ebola virus has been uninterruptedly circulating in humans since 1976.The City Department of Health has found out that a very infectious strain of influenza (transmission probability 0.3) is likely to hit soon for which the current vaccine is not effective. So far the DOH think about 100 people in the city have been infected. We know that influenza illness usually lasts for an average of 5 days and for every 1000 people who get influenza 1 person requires intensive care for 2 days. The population in the city is 80,000. The R0 (the basic reproductive rate) for this strain of influenza has initially been estimated to be 4. What is the likely contact rate for this epidemic of influenza?A pandemic disease outbreak affects more parts of the world than an epidemic outbreak.

- A researcher enrolled 100 subjects into a study on September 1, 2000. All of the subjects were at risk for developing Influenza A. On November 1, 2000, 10 subjects developed Influenza A. On December 1, 2000, 10 more subjects developed Influenza A. None of the remaining subjects developed Influenza A and none of these subjects left the study. The study ended on March1, 2001. Calculate the incidence density of Influenza A from September 1, 2000 to March 1, 2001. Show your work.Sub-Saharan Africa is epicenter of two major pandemics: HIV/AIDS and Tuberculosis (TB). Although people living with HIV/AIDS can receive antiretroviral therapy and live many years, they are extremely susceptible to co-‐infections. Even with medication, the combination of HIV/AIDS and TB is often fatal. In Swaziland, a small country nestled in Southern Africa, the total population in 2010 was only 449,900 people. Of that population, the total number of people living with HIV/AIDS was 33%. In 2010 the total number of deaths in Swaziland was approximately 13,000. In the same year the number of HIV-related deaths was reported as 9,300. Question: What was the cause-specific mortality rate from HIV per 1000 people? (round to the nearest whole number)? What is the proportionate mortality from HIV/AIDS in this population? (give your answer as a percent and round to the nearest whole number)What patterns do you detect? Often in disease outbreak investigations we want to see a pattern for a particular problem.

The number of cases of a disease at the midpoint of any year.A virus is transmitted by contact and if you are first infected, you will remain a carrier for an indefinite period. In an isolated population with "P" persons, is the infection rate at time "t" (in months after 1.jan 2020) proportional to the product of(1) the number of y (t) infected,(2) the number who are not infected,i.e the infection follows logistic growth. One tenth of the population is infected 1.jan -2020.If one-fifth of the population is infected one month later, how many are infected one year later?Which of the following displays the time course of a disease outbreak?
