For 2012-2015 rates, population estimates were from Esri Demographics, a geographic information systems software program. All population estimates exclude the City of Berkeley, which is its own health jurisdiction. - For detailed descriptions of methods and rate interpretation, please refer to the Summary of Communicable Diseases in Alameda County, 2007-2013 disease using this method allows for direct comparisons of disease incidence across two or more populations of differing sizes. - Rate calculations: Crude incidence rates were calculated to describe the number of new disease incidents occurring in 100,000 people at risk for infection during a specific time period. Standardizing the frequency of - Confidence interval (CI) interpretation: CIs were calculated to estimate the reliability of rates, which are subject to random variation. CIs represent an interval within which the true underlying rate of disease may lie; that is, assuming the absence of bias, if the same population were repeatedly sampled, 95% of the 95% CIs calculated would contain the true rate of disease. A CI's width indicates the precision and variability of the rate estimate; the narrower the CI, the larger the size of the sample from which the estimate was drawn and therefore the more precise and less variable the estimate. In this report, rates and CIs were not calculated for diseases and time periods with fewer than 10 total incidents and average annual rates and CIs were not calculated for diseases with fewer than 10 average annual cases because estimates based on such small sample Alameda County population (excluding the city of Berkeley) estimates for 2011 to 2015 were as follows: 2011: 1,410,275; 2012: 1,420,375; 2013: 1,430,448; 2014: 1,452,078; 2015: 1,463,818 - For reportable disease counts rates for California and United States, please refer to the following reports: A) California counts and rates (California Department of Public Health): B) U.S. counts and rates (Centers for Disease Control and Prevention): * Counts and rates for Alameda County in these reports may differ from those presented in these tables due to the use of a different date to define disease year. 1) Yearly Summaries of Selected General Communicable Disease in California, 2011-2016: https://www.cdph.ca.gov/Programs/CID/DCDC/CDPH%20Document%20Library/YearlySummariesofSelectedCommDiseasesinCA2011-2016.pdf 2) Vaccine-Preventable Disease Surveillance in California, 2014 and 2015 Annual Reports https://www.cdph.ca.gov/Programs/CID/DCDC/CDPH%20Document%20Library/VPD-AnnualReport2014.pdf https://www.cdph.ca.gov/Programs/CID/DCDC/CDPH%20Document%20Library/VPD-AnnualReport2015.pdf 2014: https://www.cdc.gov/mmwr/volumes/63/wr/mm6354a1.htm?s_cid=mm6354a1_w 2015: https://www.cdc.gov/mmwr/volumes/64/wr/mm6453a1.htm Number of Cases and Incident Rates of Acute Communicable Disease in Alameda County, 2011-2015 Final version: January 2019 Page 4 of 4
