Tanning beds and sunbathing may be linked to a greater risk of developing endometriosis, according to a new study. Leslie Farland, an assistant professor at the University of Arizona College of Public Health and the leader of the research, said the association between endometriosis and melanoma may reflect a common genetic background or an underlying association between sun exposure and risk of endometriosis.

A lot of what we hear about the pandemic and its impacts has focused on hospitalizations and deaths. As those numbers stack up, the implications of this virus become fearfully clear. But what about everyone else who has contracted COVID-19?

Tucson Mayor Regina Romero is set to ask the City Council to consider establishing a mandatory nightly curfew in the city starting at 8 p.m. Tuesday, Dec. 1. Pima County is already under a voluntary curfew. “The epidemiology of this outbreak is well known and described, and if we do nothing, there are enough susceptible Arizonans left to sustain this outbreak for many, many weeks past Christmas and achieving levels of transmission that pale in comparison to what we’re seeing today,” said Dr. Joe Gerald, an associate professor with the UA’s Zuckerman College of Public Health.

Despite warnings, millions traveled and gathered for Thanksgiving. As officials brace for the surge ahead, they say a new approach is needed.
