Ans. Access to healthcare plays a vital role in determining human health and disease outcomes. Adequate access to healthcare services ensures timely diagnosis, treatment, and preventive measures for various diseases. It allows individuals to receive necessary vaccinations, screenings, and early interventions, reducing the risk of developing severe conditions. Lack of access to healthcare, on the other hand, can result in delayed or inadequate treatment, leading to poorer health outcomes and increased mortality rates. It is crucial to address healthcare disparities and ensure equal access to healthcare for all individuals to improve overall human health.
