COVID-19 Cases Surge in Mexico City Returning the Use of Masks

While COVID-19 isn’t causing the chaos it did in 2020 and 2021, Mexico has reported over 8,000 cases so far in 2024. In Mexico City, the resurgence of cases has prompted people to wear masks again. According to the federal Health Ministry, the number of confirmed COVID-19 cases increased each week from May 26 to June 29. These figures may still be adjusting upward. However, the recent uptick remains relatively low compared to the peaks seen in 2020 and 2021. In contrast to the data from February 2024, when case numbers peaked above 700, weekly cases ranged between 100 to 200 from May to late June 2024.

According to the Sistema de Vigilancia Epidemiológica de Enfermedad Respiratoria Viral (SISVER), Mexico reported 20,264 confirmed COVID-19 cases in 2023. So far in 2024, there have been 98,370 suspected cases, with 8,075 (8.2%) confirmed as COVID-19 positive. The cumulative positivity rate, based on preliminary laboratory data, stands at 14%.
Weekly positivity rates showed an upward trend at the start of 2024, peaking in epidemiological week 6, then declining until week 13, before gradually increasing again.

The John Hopkins Bloomberg School of Public Health highlights the significance of this metric, noting that it reflects the spread of the infection and the adequacy of testing. “A high percent positive means that more testing should probably be done – and it suggests that it is not a good time to relax restrictions aimed at reducing coronavirus transmission,” reported the John Hopkins Bloomberg School of Public Health.
