"Omicron's explosive growth in Houston continues unrelentingly. It is now poised to be the dominant cause of COVID-19 in our Houston Methodist patients," a spokesperson for the hospital said.
According to Houston Methodist, the variant is doubling every two to three days among COVID patients and only half of the patients sick with omicron have been vaccinated with two or three doses.
"A booster vaccine dose is your best defense against serious COVID disease," according to a statement.
