Scenario: A local epidemiologist is trying to find the attack rate in two communities ravaged by a Measles outbreak. Community A has 892 members, NO citizens have received the MMR (Measles, Mumps, and Rubella) vaccine due to personal beliefs and financial reasons. 486 cases have been reported in Community A.
Community B is a larger community with 10,000 people. 95% of the citizens have the MMR vaccine (assume for this example the vaccine has 100% effectiveness, it doesn't in reality). 208 cases have been reported in the Community B outbreak.
Help the epidemiologist and find out the Attack Rate for the Community A and Community B outbreaks.

Attack rate is calcu

Explanation:

Attack rate is calculated using the formula below;

Attack rate = total number new cases

                         x 100

                       total population

For community A, attack rate = 486/892 = 0.5448

0.5448 x 100 =54.5 %

For community B, attack rate = 208/10000 = 0.0208

0.0208 x 100 =2.08 %

                                                        water

                                                        halon

                                                  carbon dioxide

a colorless, odorless gas produced by burning carbon and organic compounds and by respiration. it is naturally present in air (about 0.03 percent) and is absorbed by plants in photosynthesis.
