The basic reproductive ratio for an infection was estimated to be 2.3. Which of the following BEST describes the meaning of this estimate?Select one alternative:The effective contact rate for the infection is 2.3 greater than to other infections.An average infectious individual gives rise on average to 2.3 infected individuals.The probability of contact with an infected individual is 2.3 higher compared to other diseases.The infection on average is caused by 2.3 infected individuals in a population.

A study reports a mortality rate of 6% in the experimental group and 10% in the control group. Which of the following statements is correct?Question 4Select one:a.None of options are correctb.The risk difference is 4%c.The RR is approximately 1.67d.The number needed to treat is 10e.The incidence of death is 6%
