Measles resurgence in Armenia: unmasking health system vulnerabilities and crafting comprehensive eradication strategies – a review

Abstract

Measles is an acute febrile illness associated with rashes, fever and life-threatening complications. It is a vaccine-preventable disease with the Measles Mumps Rubella(MMR) vaccine but a recent global trend unveils a resurgence of measles in various parts of the world including Armenia. Measles was declared eliminated from Armenia in 2021 before reports of local outbreaks surfaced in 2023. The WHO identified discrepancies in the vaccination coverage during COVID-19. Measles also poses a great financial burden as a public health issue worldwide. Sociocultural factors impacting measles transmission are maternal education, healthcare access, migration, vaccine hesitancy, and socioeconomic status (Table 3). Efforts to control and eradicate measles from Armenia are run by a collaborative approach of national and international health bodies such as United Nations Children’s Fund (UNICEF), WHO, Global Vaccine Alliance (GAVI), and the Ministry of Health. Thus, the resurgence of measles can be managed through widespread patient education, innovative approaches, strengthening the healthcare system and addressing vaccine hesitancy, sociocultural barriers, and humanitarian emergencies. This review investigates the complicated dynamics of measles inside Armenia’s health system in depth. A thorough examination of measles incidence and immunization patterns highlights the shift from few cases and high vaccination rates to a comeback caused by imported viruses. The causes of its recurrence have been thoroughly investigated, including reduced immunization programs and vaccine hesitancy. The research delves further into the ‘One Health’ idea, assessing the possibility of interspecies transmission among nonhuman primates and examining the environmental factors that influence measles transmission. Among the challenges are weaknesses within Armenia’s health system as well as the possibility of interruptions from the COVID-19 outbreak. In measles vaccination status, the combination of maternal education, postnatal care, and socioeconomic variables exposes the larger drivers at work. The study concludes with a comprehensive set of public health policy recommendations covering vaccination promotion, surveillance, healthcare provider education, public awareness, international collaboration, data analysis, law enforcement, emergency preparedness, research, and coordination. The research sheds light on the tangled web of measles dynamics, health system resilience, and contextual subtleties via this multifaceted approach, inviting readers to investigate the multiple strategies required for eliminating measles in Armenia.
