Deep in the foothills of Mexico’s Sierra Juarez mountains, Juana Lazaro washes her hands vigorously, lathering up to her elbows and scrubbing between her fingers then rinsing them several times with cold water.
Lazaro had just learned about the coronavirus that was first detected late last year some 8,520 miles (13,712 km) away in the Chinese city of Wuhan and has since infected more than a million people around the world.
In her small, indigenous village of Teotitlan del Valle in the southern Mexican state of Oaxaca, few people regularly speak Spanish . . .
