Chart Not AvailableThe data are grouped by more dimensions than the chart is capable of displaying. If you would like this chart you will need to remove one or more grouping selections on the query definition builder page and then resubmit the query request or choose a different chart that supports multiple dimensions.
Hepatitis AHepatitis A is an acute liver disease caused by the hepatitis A virus (HAV). The symptoms of hepatitis A typically begin 25 to 30 days after infection with the virus and include fever, tiredness, nausea, loss of appetite, abdominal pain, diarrhea and jaundice. Adults and older children are more likely than young children to have symptoms if infected. Hepatitis A usually resolves quickly and chronic infection does not occur. HAV is found in the stool of persons with hepatitis A. Infected persons are most likely to transmit HAV in the 2 weeks before the onset of their illness. HAV is most commonly spread from one person to another, although outbreaks caused by contaminated food can occur. In 1995, hepatitis A vaccine was licensed for use in the United States and since that time the incidence of hepatitis A has fallen dramatically.

Statistical StabilityStatistical stability, reported in the data table, is based on a statistic called the "Relative Standard Error," or RSE, which is the standard error expressed as a proportion of the point estimate (e.g., 30% of the point estimate). The following conventions are used here to interpret the RSE. * A dash (-) means that the relative standard error (RSE) is below 0.30 and the count or rate may be considered stable. * "Unstable" is displayed when the RSE is 0.30-0.50. An unstable count or rate may fluctuate widely across time periods due to random variation (chance). * "Very Unstable" is displayed when the RSE is greater than 0.50. A very unstable count or rate should not be used to inform decisions. You may combine years or otherwise increase the population size used in the query to achieve a more stable count or rate. Problems with statistical instability typically occur when there is a small number of health events in a small population. For more information on statistical stability, visit the NM-IBIS Reliability & Validity page [https://ibis.health.state.nm.us/resource/ReliabilityValidity.html].
Infectious Disease DataInfectious disease data on NM-IBIS are updated nightly. When querying data by month or year, please be aware that data for the current time period will not be complete until after the end of the time period (i.e., after the end of the month or year).
Data for the current year are provisional and may change significantly upon the completion of ongoing investigations. Data for prior years are also subject to minor revisions due to corrections or identification of historical cases.
For MMWR Week calendar dates, please see [http://ibis.health.state.nm.us/resources/MMWRWeekCalendar.html].
When querying data by race/ethnicity, please be aware that cases missing race/ethnicity information may not be displayed as a separate category, but will be included in the "Total" row, reflecting overall New Mexico counts or rates.[[br]][[br]]
Denominator for Rate CalculationA disease incidence rate is the number of persons who became ill in a given time period divided by the number of persons at risk during the same time period. Incidence rates in this IBIS module use a year as the time frame of reference and "person-years" in the denominator of the calculation. For events counted over an entire year, person-years is the total (July 1) population for that geography and sub-population (e.g., age group). For monthly estimates, person-years is calculated as the annual population divided by 12. To get current population estimates for New Mexico, use the IBIS Query module for population estimates.
Rates for 2017 are currently calculated using 2016 population estimates.

Infectious Disease DataDisease incidence data are derived from reports of notifiable infectious diseases. NMDOH relies on health care providers, laboratories, hospitals, clinics, institutions and individuals to report suspected and confirmed notifiable infectious diseases in accordance with New Mexico Administrative Code 18.104.22.168. Under-reporting can occur due to of lack of awareness about reporting requirements or lack of compliance with those requirements. Not all cases of infectious diseases can be detected for various reasons including lack of access to health care services, lack of laboratory testing or concerns about confidentiality. Specific and standardized national case definitions are used to classify disease reports by case status. To report a disease incident included in the Administrative Code, contact the Epidemiology and Response Division at the New Mexico Department of Health, 505-827-0006.[[br]][[br]]
Population DataPopulation estimates for previous years are occasionally revised as new information becomes available. When publishing trend data, always be sure that your rates for earlier years match current rates on NM-IBIS that have been calculated with the most up-to-date population estimates.
