Pertussis by County, New Mexico, 2015-2019

Indicator Report Data View Options

Why Is This Important?

Pertussis or "whooping cough" is a highly contagious respiratory tract infection caused by the Bordetella pertussis bacteria. Since vaccine-induced immunity to Bordetella pertussis is of limited duration, many adolescents and most adults have little or no residual immunity. Most reported pertussis cases among adolescents and adults are thought to occur because of this decline in protective immunity. Infants who are too young to have been fully vaccinated are at high risk of severe and potentially life-threatening illness from exposure to persons with active disease. Pertussis vaccine led to a dramatic decrease in the incidence of the disease, from approximately 150 cases per 100,000 population pre-vaccine in the 1940s to about 1 case per 100,000 by 1980; however, pertussis disease rates have increased since 1980.

Pertussis by County, New Mexico, 2015-2019

  • #This count or rate is statistically unstable (RSE >0.30), and may fluctuate widely across time periods due to random variation (chance). Please use caution in interpreting this value, or combine years, areas, or age groups to increase the population size.
  • ##The estimate has a relative standard error greater than 50% and does not meet standards for reliability. A count or rate such as this should not be used to inform decisions. Try combining years, areas, or age groups to increase the population size.

Definition

The number of probable and confirmed cases of Pertussis per 100,000 population (person-years at risk). Includes confirmed and probable cases.

Data Sources

  • U.S. Data Source: Centers for Disease Control and Prevention, National Notifiable Diseases Surveillance System (NNDSS)
  • New Mexico Population Estimates: University of New Mexico, Geospatial and Population Studies (GPS) Program.

How the Measure is Calculated

  • Numerator:

    Number of confirmed and probable pertussis cases that occurred during the measurement (time) period.
  • Denominator:

    Estimated total population at risk during the measurement (time) period.

Data Issues

  • New Mexico Population Estimates

    All population estimates apply to July 1 of the selected year. These estimates are considered the most accurate estimates for the state of New Mexico and should match those found on the University of New Mexico Geospatial and Population Studies website. Estimates include decimal fractions. Census tract population estimates were summed to produce County and Small Area population estimates. Population estimate totals may vary due to rounding. Population 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.

  • New Mexico Electronic Disease Surveillance System (NM-EDSS)

    Disease 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 7.4.3.13. 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.
