MEASLES: VACCINATION COVERAGE AND REASONS FOR THE RESURGENCE OF THE DISEASE

Abstract

Abstract: Measles is a highly contagious acute viral infection and remains one of the most important vaccine-preventable diseases worldwide. Despite the availability of an effective and safe vaccine, measles outbreaks continue to occur in different regions, especially where vaccination coverage is insufficient. The resurgence of measles in recent years has been associated with gaps in routine immunization, missed vaccination opportunities during the COVID-19 pandemic, migration, vaccine hesitancy, unequal access to health-care services, and the accumulation of susceptible individuals in certain communities. The purpose of this article is to analyze the epidemiological characteristics of measles, the role of vaccination coverage in controlling transmission, and the major factors contributing to the re-emergence of the disease. The study is based on a review of scientific literature and international public health recommendations. The findings indicate that maintaining high two-dose vaccination coverage, strengthening epidemiological surveillance, identifying unvaccinated individuals, improving public awareness, and ensuring timely outbreak response are essential for controlling measles. Sustained immunization efforts and strong public health systems are necessary to prevent future outbreaks and reduce measles-related complications and mortality.
