Introduction

Infectious and communicable diseases have major impacts on public health worldwide. Understanding the causative agents, modes of transmission, prevention strategies, and community implications is crucial for effective control and management. This paper explores tuberculosis (TB) as an example of an infectious disease, examining its causative agents, transmission routes, prevention methods based on the three levels of prevention, and its epidemiological status as reported by the CDC. Additionally, it discusses the role of community health nurses in disease prevention and control to improve health outcomes in affected populations.

Disease Description and Causative Agents

Tuberculosis is a serious infectious disease primarily caused by the bacterium Mycobacterium tuberculosis. It predominantly affects the lungs but can also involve other organs (World Health Organization [WHO], 2023). The bacteria spread via airborne particles when an infectious individual coughs, sneezes, or talks, releasing aerosols laden with M. tuberculosis. These aerosols can remain suspended in the air for hours in enclosed environments, making transmission highly efficient in crowded or poorly ventilated settings.

Modes of Transmission

The primary mode of TB transmission is through inhalation of airborne droplets containing the bacteria from a person with active pulmonary TB. Close contacts and individuals in congregate settings like prisons, healthcare facilities, and homeless shelters are at higher risk (CDC, 2022). The transmission depends on factors such as bacterial load, duration of exposure, and environmental ventilation. There is no evidence of TB spreading through surfaces or casual contact, making airborne transmission the critical pathway.

Prevention Strategies Based on the Three Levels of Prevention

Prevention of TB encompasses primary, secondary, and tertiary levels:

• Primary Prevention: Focuses on preventing infection before it occurs. Routine BCG vaccination in endemic areas is an example; it offers protection against severe forms of TB in children (WHO, 2023). Educational campaigns promoting respiratory hygiene, cough etiquette, and adequate ventilation also serve as primary measures.
• Secondary Prevention: Aims at early detection and treatment of latent TB infection (LTBI) and active TB disease. Screening programs using tuberculin skin tests (TST) or interferon-gamma release assays (IGRAs) identify infected individuals early. Prompt initiation of anti-tubercular therapy reduces disease progression and transmission (CDC, 2022).
• Tertiary Prevention: Involves managing active TB cases to prevent complications, reduce transmission, and restore health. Directly Observed Therapy (DOT) ensures adherence to treatment regimens, which is pivotal in reducing drug resistance and ensuring cure (WHO, 2023).

Prevalence and Control According to CDC

The CDC reports that TB incidence has declined in the United States over recent years, with approximately 2.4 cases per 100,000 population in 2022 (CDC, 2022). Despite this decline, TB remains a significant global health problem, particularly in low- and middle-income countries. Multidrug-resistant TB (MDR-TB) poses challenges to control efforts, increasing morbidity and mortality rates (WHO, 2023).

The global burden of TB results in approximately 1.5 million deaths annually, underscoring the importance of sustained public health interventions. Control strategies include strengthening health systems, ensuring access to diagnostic and treatment services, and addressing social determinants such as poverty and HIV co-infection, which increase susceptibility (WHO, 2023).

Implications in the Community and Role of Community Health Nurse

Communities affected by TB face social stigmatization, economic hardship, and barriers to healthcare access. The disease burden extends beyond individual health, impacting families and community productivity. Community health nurses play a pivotal role in TB control by conducting community outreach, education, screening, advocating for at-risk populations, and supporting adherence to treatment regimens (Adams & Price, 2020).

Community health nurses also facilitate contact tracing, coordinate with healthcare facilities, and promote policies that improve ventilation and reduce overcrowding. Their cultural competence enables them to tailor interventions effectively, address misconceptions, and foster trust within communities. These efforts are essential for early identification, preventing transmission, and ultimately reducing TB prevalence.

Conclusion

Tuberculosis exemplifies an infectious disease with complex transmission dynamics and significant public health implications. Prevention strategies aligned with the three levels of prevention—vaccination, screening, and treatment adherence—are vital for controlling its spread. Community health nurses are integral to these efforts, serving as advocates, educators, and care coordinators within communities. Continued research, investment in healthcare infrastructure, and community engagement are necessary to eradicate TB and address ongoing challenges such as drug resistance and social disparities.
