Introduction
This essay explores key public health challenges in the Philippine context from the perspective of a nursing student, drawing on principles from the Department of Health (DOH) and broader public health frameworks. It addresses three interconnected areas: the One Health Approach (OHA) for managing zoonotic and environmental health issues in a coastal barangay; the persistence of communicable diseases in urban poor communities; and strategies to overcome vaccine hesitancy under the National Immunization Program (NIP). By analysing these scenarios, the essay integrates human, environmental, and social factors, proposes multisectoral interventions, and highlights the nurse’s role in public health leadership. This structure allows for a comprehensive examination of how nursing practice can contribute to sustainable health outcomes, supported by evidence-based concepts. The discussion emphasises systems thinking, social determinants of health, and patient-centred care, aiming to demonstrate the applicability of public health principles in real-world settings.
Essay 1: One Health Approach (OHA)
The One Health Approach recognises the interconnectedness of human, animal, and environmental health, particularly relevant in scenarios involving zoonotic diseases like dengue and leptospirosis (World Health Organization, 2021). In the coastal barangay experiencing rising dengue cases, leptospirosis post-flooding, and improper waste disposal, several factors contribute to the problem. Human factors include dense population living in flood-prone areas, limited access to healthcare, and behaviours such as poor sanitation practices that exacerbate disease transmission. Animal factors involve rodents and stray dogs acting as reservoirs for leptospirosis, with mosquitoes breeding in stagnant water serving as vectors for dengue. Environmental factors encompass flooding due to climate change, inadequate waste management leading to contaminated water sources, and urbanisation disrupting natural ecosystems.
These factors interact dynamically to heighten disease risk. For instance, flooding displaces rodents, increasing human-animal contact and leptospirosis transmission through contaminated water, while waste accumulation creates breeding grounds for dengue mosquitoes (Department of Health, Philippines, 2019). This interplay forms a vicious cycle where environmental degradation worsens human health vulnerabilities, and unchecked animal populations amplify pathogen spread, illustrating systems thinking in OHA.
To address this, multisectoral strategies should be implemented, involving collaboration between the DOH, local government units (LGUs), environmental agencies, and veterinary services. Feasible interventions include community-led clean-up drives to improve waste disposal, installation of mosquito nets and rodent control measures, and reforestation efforts to mitigate flooding. Additionally, integrated surveillance systems could monitor disease trends across sectors, aligning with DOH’s OHA guidelines for zoonotic disease control.
The nurse’s role is pivotal in coordinating these efforts, conducting health education on hygiene practices, and facilitating intersectoral meetings. Nurses can also perform community assessments to identify at-risk groups, promoting preventive behaviours. Effectiveness evaluation would involve pre- and post-intervention metrics, such as reduced dengue incidence rates tracked via DOH surveillance data, community feedback surveys, and environmental indicators like decreased flood-related waste accumulation. This approach ensures sustainable, holistic interventions (World Health Organization, 2021).

Essay 2: Communicable Diseases (CD)
Communicable diseases like tuberculosis (TB), diarrhoea, and HIV persist in urban poor communities due to intertwined social determinants of health (SDOH), as outlined by the DOH and global frameworks (Marmot, 2005). Key SDOH include poverty, overcrowding, and limited education, which create environments conducive to disease spread. For example, economic hardship forces families into substandard housing, increasing TB transmission through poor ventilation, while inadequate sanitation contributes to recurrent diarrhoea.
Behavioural factors, such as non-adherence to TB treatment or risky sexual practices amid HIV stigma, compound the issue. Environmental elements like polluted water sources facilitate diarrhoea outbreaks, and economic barriers limit access to antiretroviral therapy for HIV. These factors interact; for instance, poverty drives behavioural risks like unsafe water consumption, while environmental degradation exacerbates economic strain by reducing productivity through illness.
Current programs, such as the DOH’s National TB Program and HIV initiatives, face limitations including insufficient funding, leading to stockouts of medications, and poor community engagement, resulting in low uptake (Department of Health, Philippines, 2022). Gaps also exist in addressing SDOH holistically, with programs often focusing on treatment rather than prevention, and failing to integrate economic support like livelihood programs.
Proposed integrated strategies include a sustainable public health response combining education, infrastructure improvements, and economic empowerment. For example, partnering with LGUs for water sanitation projects, implementing community-based TB screening with incentives, and expanding HIV awareness campaigns via social media to counter stigma. These should be evidence-based, drawing on successful models like the DOH’s integrated management of childhood illnesses.
Nurses play a leadership role in community engagement, organising health brigades for screening and education, advocating for policy changes, and fostering partnerships. By leading support groups, nurses can enhance adherence and build trust, ultimately reducing disease burden through empowered communities (Marmot, 2005).

Essay 3: National Immunization Program (NIP)
Vaccine hesitancy poses a significant challenge to the Philippine NIP, which aims to protect children against preventable diseases (Department of Health, Philippines, 2023). In this case, the child has likely missed essential vaccines such as the pentavalent vaccine (DTP-HepB-Hib, preventing diphtheria, tetanus, pertussis, hepatitis B, and Haemophilus influenzae type b), oral polio vaccine (OPV, against poliomyelitis), pneumococcal conjugate vaccine (PCV, against pneumonia and meningitis), and measles-containing vaccine (MCV, against measles). These are part of the routine schedule for infants and toddlers under the NIP.
These vaccines are critical in the Philippine context due to high endemic rates of these diseases; for example, measles outbreaks have been recurrent, with over 40,000 cases reported in 2019, exacerbated by low immunization coverage (World Health Organization, 2019). The tropical climate and dense populations facilitate rapid transmission, making vaccination essential for reducing child mortality, aligning with DOH goals to achieve 95% coverage.
Missed vaccinations have severe consequences. Individually, the child risks life-threatening illnesses like pertussis or measles complications, including pneumonia or encephalitis. At the community level, reduced herd immunity increases outbreak risks, potentially overwhelming healthcare systems and perpetuating cycles of poverty through healthcare costs.
To address the mother’s concerns, a patient-centred, evidence-based communication strategy is vital. Using motivational interviewing, the nurse would empathise with fears from social media misinformation, then provide factual information from DOH resources, such as explaining that side effects like mild fever are rare and outweighed by benefits (e.g., vaccines prevent millions of deaths annually, per WHO data). Visual aids and testimonials could build trust.
Strategies for completion include catch-up scheduling at local health centres, home visits for follow-ups, and incentives like free consultations. Community education sessions could normalise vaccination.
This case reflects broader vaccine hesitancy issues, often fuelled by misinformation, eroding herd immunity and leading to resurgences of diseases like measles. Addressing it requires systemic efforts to counter disinformation and strengthen public trust (World Health Organization, 2019).

Conclusion
In summary, this essay has analysed public health challenges through the lenses of OHA, communicable disease persistence, and vaccine hesitancy, proposing integrated, nurse-led interventions grounded in DOH principles. By addressing human-animal-environment interactions, SDOH, and patient concerns, these strategies promote sustainable health outcomes. The implications for nursing practice underscore the need for multisectoral collaboration and evidence-based advocacy to enhance community resilience, ultimately contributing to national health goals in the Philippines. Further research could explore long-term evaluation metrics to refine these approaches.
