AGUILAR-GAMBOA, Franklin Rómulo  and  SUCLUPE-CAMPOS, Danny Omar. Molecular epidemiology of the measles virus in the region of the Americas: Current overview. Rev. Fac. Med. Hum. [online]. 2020, vol.20, n.3, pp.478-488. ISSN 1814-5469.


Measles is one of the most contagious diseases that affect humans. After its eradication in the Americas region in 2016, it has re-emerged, and the number of cases is progressively increasing.


To deepen and update the most important aspects of the measles virus molecular epidemiology in the Americas.


the search and analysis of the information was carried out over a period of five months (November 1, 2019 to March 31, 2020) for which the following words were used: measles, molecular epidemiology, America, outbreak, genotype, epidemic, in the PubMed, Hinari, SciELO and Medline databases Likewise, the epidemiological reports of the Pan American Health Organization (PAHO) and government entities from different countries of America were taken into account.


two lineages of the D8 genotype are spreading widely in the Americas region. And although we still cannot know the impact of the current pandemic produced by the SARS-CoV-2, the low immunization rate, the high migratory movements before 2020, socio-cultural and religious factors in addition to the social and political crisis that affect some countries in the region, are helping to increase this problem.


The review provides knowledge of the molecular epidemiology of the virus. Its use and correct interpretation will allow us to establish adequate management and containment measures in order to recover the eradicated disease condition in the Americas.
