Public Health Foundations Questions
Question 1 of 5
In many countries, the key method of fighting the COVID-19 pandemic in 2019-2020 was the so-called flattening the epidemic curve that serves to: 1) reduce the overall number of cases; 2) spread the number of cases over time; 3) slow down the rate of spread of SARS-CoV-2 infection; 4) counteract the paralysis of treatment under the pressure of new cases; 5) gain time to develop treatment procedures and vaccines.
Correct Answer: D
Rationale: Flattening the curve aims to spread cases (2), slow spread (3), prevent healthcare overload (4), and buy time (5); it doesn’t inherently reduce total cases (1).
Question 2 of 5
Epidemiological surveillance of hospital-related infections in healthcare includes all the following except for:
Correct Answer: D

Question 3 of 5
In 2017 in a place populated by 50000 inhabitants there were the following numbers of injuries according to causes and deaths resulting from those injuries: The formula for the calculation of mortality rate per 100,000 resulting from violence is:
Correct Answer: A
Rationale: Mortality rate = (deaths from violence / population) x 100,000 = (5 / 50,000) x 100,000 = 10.
Question 4 of 5
According to NHS Scotland data in the last decade the participation in cytological screening has dropped from 80% to 70% in women aged 25-34 with low education. Indicate health effects of this situation:

Correct Answer: D
Rationale: Mortality rate = (deaths / population) x constant, using the average population as the denominator.
