The population of a village was about 10,000 on 1/1/2017, of which 1000 have a history of measles prior to 2017. During 2017, 900 subjects developed measles. During a survey carried out on 1/2/2017, 100 persons were found to be ill with the disease on that day, and 20 of them actually developed the disease on that day. During 2017, 90 of those who developed measles died from the disease, none of them died in January. Altogether, there were a total of 200 deaths from all causes in that population during that year.
