Before she got COVID-19, Cassandra Hernandez, 38, was in great shape — both physically and mentally.
"I'm a nurse," she says. "I work with surgeons and my memory was sharp."
Then, in June 2020, COVID-19 struck Hernandez and several others in her unit at a large hospital in San Antonio.
"I went home after working a 12-hour shift and sat down to eat a pint of ice cream with my husband and I couldn't taste it," she says.
The loss of taste and smell can be an early sign that COVID-19 is affecting a brain area that helps us sense odors.
