Infectious disease surveillance is essential to identify outbreaks and emerging infections, effectively and rapidly provide testing, treatment, and preventive measures, and monitor trends to inform prevention strategies. For example, nine out of ten individuals who are exposed to measles will become infected if they are not vaccinated. Prompt recognition of those exposed is essential so post-exposure vaccine can be given within 72 hours to prevent infection.
In 2023, the Indiana General Assembly passed HEA 1457, which will allow a local health officer to issue a birth, death, or stillbirth certificate from the electronic registration system regardless of the location of the filing of the record. Planning is underway to implement this legislation statewide by Jan. 1, 2025. Natural disasters, such as floods and tornadoes, can damage or destroy vital records documents that Hoosiers need for identification. Adopting an emergency action plan in each county will ensure Vital Records services are available during a disaster.
Indiana witnessed an increase in youth e-cigarette use from 3.8% in 2012 to 19.8% in 2021 among high school students. Most e-cigarettes contain nicotine, which is highly addictive and can harm youth brain development. The first step in addressing tobacco and addictive nicotine prevention is building and maintaining a tobacco-free coalition that represents the whole community.
As of January 1, 2023, Indiana health care providers are required to offer blood lead testing to all children under age 2 years. Through August 31, 2023, there has been a 21% increase in unique children tested for elevated blood lead levels, with 10,588 more blood lead tests reported, compared to the same time period in 2022. Comparing January-August, 2022 and January-August 2023, there is a 393% increase in confirmed elevated blood lead levels. There is no safe level of lead for children and the developmental and neurological damage caused by lead exposure during childhood will last a lifetime.
An estimated 13 million people in the U.S. have latent tuberculosis infection (LTBI). Without treatment, one in 10 people living with LTBI will get sick with TB disease. Eliminating TB in the US requires expanding testing and treatment of LTBI. Testing for TB infection should be a routine and integral part of health care for patients with increased risk for TB. Each patient needs appropriate health care, treatment, and support services to reduce the spread of infection and development of drug resistance.
Over 1 million students attend K-12 schools in Indiana, and school health liaisons support schools across the state. Research shows that healthier students learn better and have greater academic success, leading to a lifetime of better health outcomes. Providing access to health services, such as vision, hearing and dental screenings, while limiting youth risk behaviors, supports community, physical, and intellectual development that can continue into adulthood.
In Indiana, pest and vector control is a crucial aspect of public health and environmental management. The state employs a variety of strategies to manage and abate pests such as mosquitoes, ticks, and rodents, which can pose significant health risks and disrupt daily life. Local health departments collaborate with state agencies to monitor pest populations, implement targeted treatments, and promote community awareness about prevention measures. Integrated pest management practices are often utilized, combining biological, cultural, and chemical methods to effectively reduce pest populations while minimizing environmental impact. These efforts are vital for controlling the spread of diseases and maintaining the quality of life for residents across Indiana.
In 2023, 78% of all Indiana children had one measles-mumps-rubella (MMR) vaccine by age 35 months, compared to 89% in 2019. Community immunity against measles requires about 95% of a population to be vaccinated to prevent outbreaks. Providing accessible immunization services will help maintain robust immunization rates for disease prevention.
Preparedness saves lives by enduring timely and effective response to public health emergencies such as natural disasters and disease outbreaks, reduces impact of these emergencies by providing essential services such as medical care, food/water, and shelter, fosters resilience among individuals and communities by enhancing their ability to recover, and protects national security.
In Indiana, preventable injuries account for the leading cause of death in individuals aged 1-44 years (CDC WISQARS), notably poisonings and motor vehicle crashes. Identifying a leading cause of injury allows effective planning and prevention of those injuries and potential deaths.
Indiana ranks 36th nationally in child mortality: from 2018-2020, Indiana’s child mortality rate was 31.3 deaths per 100,000 children ages 1-19 years, compared to the national rate of 25.9 deaths. Understanding causes of child mortality helps drive education and action to prevent these deaths.
Indiana ranks 12th highest in the US for adult obesity, with 2/3 of adults being overweight or obese. In Indiana, 1/3 of children are overweight or obese. Obesity is a common risk factor for many chronic diseases, including heart disease, cancer, and diabetes. A key step in addressing chronic disease and obesity prevention is building and maintaining a healthy community coalition that represents the whole community.
Some communities, such as those in rural areas, often face higher rates of chronic disease and limited access to health care. Access to public health services in all counties will enhance the health and well-being of all Hoosiers, reduce disease, and improve health outcomes.
Indiana ranks 41st in infant mortality, which is the death of an infant before the first birthday: in 2021, Indiana’s infant mortality rate was 6.7 deaths per 1,000 live births, compared to the national rate of 5.4 deaths. Understanding causes of infant mortality helps drive education and action to prevent these deaths.
Indiana has 240 food inspectors responsible for inspecting over 32,000 retail food establishments statewide. The risk-based food inspection method is a data-informed best practice for conducting timely routine inspections based on menu type, facility history and follow-up inspections for any complaints or issues.
Health and safety hazards may exist within housing and outdoor environments resulting in infection or injury. Examples include faulty plumbing systems, rodent or insect infestations, improper ventilation, pool inspections, onsite sewage system permits and inspections, and poor sanitation.
