Research shows the COVID-19 Delta Variant is growing in North Texas and across the country. The Delta Variant was first discovered in India. Health officials say strain makes up about 25% of COVID-19 cases locally, and it looks like it’s doubling every two weeks. Doctors are encouraging people to get vaccinated as the strain is causing a rise in cases and hospitalizations locally and nationally. Those who are already vaccinated can still get infected, but having severe symptoms and becoming hospitalized are extremely thin.
