A group of invisible heroes work the hallways at Hospital Juarez de Mexico in this capital, a metropolis that is ground zero of the Covid-19 crisis in Mexico.
Although they do not receive the same recognition as doctors or nurses, people like Manuel Aguirre, that hospital's stretcher coordinator, also are on the front lines of the coronavirus battle.
"(You have) experiences here in the hospital like seeing each person who dies, the situation of family members who" can only wait outside for updates on their loved one's condition, Aguirre said.
An economic reactivation plan kicked off this week in Mexico even though the country, which has reported 97,326 confirmed coronavirus cases and 10,637 Covid-19-related deaths, is still in a critical phase of its response to the pandemic.
Hospital staff account for more than one in five of all confirmed cases, according to the latest report from the Health Secretariat, while 23 percent of the health workers infected with the novel coronavirus are not doctors, nurses or lab technicians.
