Abstract

The swine flu pandemic, caused by the H1N1 influenza virus, significantly impacted global health, with particular repercussions for vulnerable populations. This review examines the effects of swine flu on groups at heightened risk, including children, the elderly, pregnant women, and individuals with pre-existing health conditions. Vulnerable populations experienced higher morbidity and mortality rates, primarily due to their compromised immune systems or chronic health issues. The review explores epidemiological data, clinical outcomes, and healthcare responses tailored to these high-risk groups. It highlights the disparities in access to vaccination, antiviral treatments, and healthcare resources, which exacerbated the impact on these populations. Additionally, the review discusses lessons learned from the pandemic, including the importance of targeted public health strategies and improved preparedness for future influenza outbreaks. Understanding the disproportionate effects of swine flu on vulnerable populations is crucial for developing effective interventions and policies to mitigate the impact of similar pandemics in the future.
