Texas Medical Center hospitals are seeing an uptick in patients infected with the COVID-19 Delta variant, and infections are prevalent among young children and adults who have not been immunized.
At Texas Children’s Hospital, fewer than 10 kids have been diagnosed with the Delta variant, which epidemiologists say is more transmissible than the original strain of SARS-CoV-2. Doctors have diagnosed 48 cases of the Delta variant at Houston Methodist since the end of April.
“The big concern with Delta is that it could spread like wildfire,” said Dr. James Versalovic, interim pediatrician-in-chief at Texas Children’s Hospital. Experts expect the numbers to increase in the coming days because the virus is “highly contagious” and can infect even those who have been partially vaccinated. The Delta variant is able to spread more rapidly by binding to host cells in the body. Currently, the variant accounts for one in five cases in the U.S.
Early studies of the Delta variant indicate the current COVID-19 vaccines can protect patients from severe infections. In a pre-print paper published by Public Health England, researchers found the two-dose Pfizer-BioNTech and AstraZeneca vaccines were 96 percent and 92 percent effective, respectively, against hospitalization for COVID-19. Moderna’s vaccine is also effective against Delta, the company said on Tuesday.
Breakthrough infections can occur with the two-dose vaccines, but these infections are usually far less serious than the ones affecting people who have not been inoculated.
“The common theme in Delta variant patients we see is almost none of them have been vaccinated, and that’s especially true for the people who are hospitalized,” said Dr. Wesley Long, an infectious disease expert at Houston Methodist Hospital.
The emergence of the Delta variant prompted the World Health Organization to issue a new recommendation that all people, regardless of vaccination status, resume wearing masks indoors. Because the new variant is particularly contagious in undervaccinated areas, experts worry it could overwhelm Texas.
“It does raise some concern, because people are no longer practicing social distancing and they’re less consistent about wearing masks,” said Dr. Robert Atmar, professor of infectious diseases at Baylor College of Medicine. “Those individuals who aren’t vaccinated are at risk of getting sick or of needing hospitalization, and the rest of us who are vaccinated could still potentially (become infected).”
There’s basically zero chance that we get another mask mandate in Texas, and there’s no opportunity for the city or Harris County to issue one, either. I have started not wearing masks in indoor spaces, in recognition of my and my family’s vaccinated status, but I may reconsider that. Certainly, anyone with kids under the age of 12 should continue being cautious. Beyond that, it’s the same song, different verse: We need more people to be vaccinated. That is what will greatly slow down the spread of this variant and others like it, and will ensure we don’t have any more spikes in the hospitalization rate. It’s as simple as that.
