Introduction

Communicable diseases continue to pose significant public health challenges worldwide. They contribute markedly to morbidity and mortality, especially in vulnerable populations. Applying epidemiological concepts and nursing research is essential in understanding, preventing, and controlling these diseases. This paper focuses on tuberculosis (TB), a longstanding and potent communicable disease that remains prevalent globally. It explores the disease's etiology, modes of transmission, clinical presentation, treatment, and complications. Additionally, the paper investigates the demographics most affected, considers health determinants influencing disease patterns, examines the epidemiologic triad, and discusses the vital role of public health nursing in disease management.

Description of Tuberculosis

Causes: Tuberculosis is caused by the bacterium Mycobacterium tuberculosis. It primarily affects the lungs but can also involve other organs, leading to extrapulmonary TB. The bacteria are slow-growing and transmit through droplet nuclei released into the air when an infected individual coughs, sneezes, or talks.

Mode of Transmission: The primary mode of transmission is airborne. When an individual with active pulmonary TB expels infectious droplets, others inhaling these droplets may become infected. The risk of transmission depends on factors such as duration of exposure, ventilation, and infectiousness of the source case.

Symptoms: Active TB presents with persistent cough lasting more than three weeks, hemoptysis, chest pain, fever, night sweats, and weight loss. Latent TB infection, by contrast, is asymptomatic but can reactivate, leading to active disease.

Treatment and Complications: The standard treatment involves a lengthy course of multiple antibiotics, typically isoniazid, rifampin, ethambutol, and pyrazinamide for at least six months. Non-adherence or inadequate treatment can lead to drug-resistant TB, which complicates management. If untreated, active TB can cause lung destruction, dissemination, and death.

Affected Demographics

TB affects populations differently worldwide. Globally, it is most prevalent among socioeconomically disadvantaged groups, including urban poor, Indigenous populations, and individuals with HIV/AIDS. In the United States, minorities, including foreign-born persons and prisoners, are disproportionately affected. Data indicate higher incidence and prevalence rates in these groups, with significant morbidity and mortality, especially when co-infected with HIV. For example, according to the CDC (2021), minority populations account for approximately two-thirds of TB cases in the US, with significant disparities in disease outcomes.

Determinants of Health

Several determinants influence TB epidemiology. Socioeconomic status plays a critical role, affecting living conditions, nutrition, and access to healthcare. Social determinants such as housing density and incarceration increase exposure risk. Healthcare access determines early diagnosis and treatment adherence. Additionally, comorbid conditions like HIV weaken immunity, facilitating disease progression. Public health infrastructure, including surveillance and contact tracing, also impacts disease control efforts.

Epidemiologic Triad

The epidemiologic triad comprises host, agent, and environment. In TB:

  • Host: Human hosts with varied vulnerability based on immune status, age, and genetic predisposition.
  • Agent: Mycobacterium tuberculosis, a resilient bacterium capable of dormancy within hosts.
  • Environment: Enclosed, poorly ventilated settings facilitate airborne transmission. Overcrowding in prisons and homeless shelters exemplify high-risk environments.

This triad underscores that controlling TB requires attention to all three factors, emphasizing the importance of reducing exposure and enhancing host resistance through vaccination and treatment.

Role of the Public Health Nurse

Public health nurses are crucial in TB prevention and control. They participate in case finding through screening programs, especially among high-risk populations. They facilitate reporting of cases to health authorities, ensuring timely public health response. Data collection and analysis by nurses help identify transmission patterns, evaluate intervention effectiveness, and prioritize resource allocation.

Nurses also provide directly observed therapy (DOT), ensuring treatment adherence, reducing drug resistance risks. They conduct contact investigations, offering testing and prophylactic treatment to exposed individuals. Follow-up includes monitoring for treatment side effects, supporting patients psychologically, and educating communities about transmission prevention.

Furthermore, public health nurses advocate for policies addressing social determinants, collaborate with community organizations, and promote health education to reduce stigma and improve health literacy. Their multifaceted role is integral to the containment and eventual eradication of TB.

Conclusion

Understanding the epidemiology of tuberculosis through the lens of the epidemiologic triad reveals the complexity of disease transmission and persistence. Public health nursing plays a pivotal role in early detection, treatment, and prevention, especially among vulnerable populations. Continued investment in surveillance, community engagement, and addressing social determinants are imperative to reducing TB burden globally and locally. As healthcare providers and advocates, nurses are at the forefront of efforts to eliminate this ancient yet persistent disease.
