TIJUANA
Nearly a year after the coronavirus forced Nadley Morales into a harsh and lonely isolation, public health officials showed up on her door-step in one of Tijuana’s upscale neighborhoods.
It took the researchers almost 15 minutes just to persuade the 61-year-old to open the door so her son could get a COVID-19 test. “And with good reason,” she later said, given Tijuana’s high rate of positive tests and high death rate from the disease, and her own diabetes.
Scientists and students from the Autonomous University of Baja California began ringing Baja doorbells on Feb. 1, offering free COVID-19 testing as part of a research study to better understand the infection rates of a disease that moves freely between borders.
