The epidemiological behaviour of the main extraintestinal complication due to E. histolytica (amoebic liver abscess, ALA) has been little explored in developing countries. Since Mexico meets the characteristics to be considered as endemic, the aim of this work was to analyze the national surveillance data (seven years) of ALA issued by the General Directorate of Epidemiology. An analysis of cases and incidence of ALA (2014–2020) was performed in the annual reports issued by the GDE in Mexico. Cases and incidence of ALA were classified by year, incidence, age group, sex and seasons. Geographical distribution map for the whole country of ALA was constructed. The cases and mean incidence of ALA did not shown significant variation during the study period. Of the total cases accumulated, Sonora, Sinaloa, Nayarit, Colima and Zacatecas states showed the most incidence by ALA. Male sex of 24–44 years old showed higher ALA cases. No temporal behaviour was identified between the ALA cases. In Mexico, the incidence of ALA remains unchanged, however, it should not be underestimated since the monitoring programs for the search for new cases have not yet been implemented mainly in endemic states. These results summarize the priority in the national ALA report.
