After the COVID-19 crisis came to Connecticut, the New Haven office of Comprehensive Dental Health shut down completely for two weeks. Later, Dr. Joseph Tagliarini began opening the office a few days a week with a skeleton crew to handle emergencies. Now the office is operating at nearly full staffing—with six full-time and six part-time employees. Nobody on the staff has gotten sick, and Tagliarini wants to keep it that way. He hopes the health care industry will produce a new generation of tests for the virus that will be simple, inexpensive, and accurate, and will deliver results on the spot.
