Mexico's COVID-19 pandemic death toll has passed 345,000, though most states have not seen any rebound in coronavirus cases.
There have been more than 215,500 test-confirmed deaths related to COVID-19, but Mexico does so little testing that many people die without having been tested.
A preliminary government review of death certificates suggested excess deaths attributable to COVID-19 reached 316,344 by the start of March.
There have been 29,395 test-confirmed deaths since then, for a total of 345,739, health officials said on Tuesday.
The Caribbean coast state of Quintana Roo, home to the resort of Cancun, has seen an uptick in cases as has the Pacific coast state of Colima.
Authorities believe increased Easter-week tourism in Quintana Roo may have contributed to the increase in infections.
The government on Tuesday also announced plans to start vaccinating people between 50 and 59. Previously, only frontline health care personnel, teachers and those over 60 had been eligible for the shots.
Officials have administered 16.7 million doses to date, a small amount given the country's population of 126 million. Like many countries, Mexico has had a difficult time getting enough vaccines.
