As US regional health authorities reacted with alarm to a jump in child Covid infections that caused some school districts to announce returns to remote learning, a leading public health official questioned the need for schools to close, saying: “We know how to keep schools open, we know how to keep them safe.”
Over the past three weeks, as Omicron-related cases soared in New York City and elsewhere, the number of children hospitalised in New York with Covid-19 quadrupled, the state health department said.
The California state epidemiologist Dr Erica Pan wrote on Twitter: “Unfortunately New York is seeing an increase in pediatric hospitalisations (primarily amongst the unvaccinated), and they have similar [five – to 11-year-old] vaccination rates.”
Across New York state, about 16% of five- to 11-year-olds and 71% of 12- to 17-year-olds are fully vaccinated.
“Please give your children the gift of vaccine protection as soon as possible as our case [numbers] are increasing rapidly,” Pan wrote.
Rising numbers of pediatric cases have convinced officials in some states to order a return to remote learning after the winter break. Around 300 schools in Maryland, New Jersey, New Mexico and New York will remain closed.
In Mount Vernon, a New York suburb, virtual learning is scheduled until at least 18 January.
“I have been very reluctant to close schools but given the current trends in Covid cases it would be risky not to do so,” district superintendent Kenneth Hamilton wrote.
In Maryland, Prince George’s county public schools, one of the 20 largest districts in the US, transitioned more than 136,500 students to virtual learning last week.
The district chief executive, Monica Goldson, told families staff “must be able to deliver in-person instruction and other activities in conditions that prioritise their own health, as well as the wellbeing of the school community.
“The increased positivity rates have significantly challenged the ability to do so, causing anxiety among many school communities and disruption to the school day.”
In New Jersey, Paterson public schools will start 2022 with two weeks remote.
“A surge of new cases has occurred in north-eastern New Jersey and it is expected that the trend will continue through the holiday break,” said the superintendent, Eileen Shafer.
Some officials have expressed frustration. Dan Domenech, director of the School Superintendents Association, told Newsweek: “Just when we thought this past October – when we had about 98% of kids back in schools in person – that things were moving in the right direction, here we are right back where we were last year.”
On Sunday, a leading health expert questioned the need for any schools to close.
Ashish Jha, dean of the Brown University School of Public Health, told Fox News Sunday: “We know how to keep schools open, we know how to keep them safe. This really shouldn’t even be on the table. I’m disappointed to see this happening.
“We know that for kids being in school is the right thing for them, for their mental health, for their education. And we have all sorts of tools to keep schools open so I don’t really understand why school districts are [closing schools].
“… There could be times when you have such severe short staffing shortages that it may be hard to keep schools going. That really should be the only context I think at this point.”
Concern about Omicron infections among children remains high, however. On Friday, Christmas Eve, the New York health department warned healthcare providers of rising numbers of child hospitalisations around New York City, where Omicron was first recorded on US soil.
The department warned that admissions rose four-fold from the week starting 5 December to the week starting 19 December. Approximately half the admissions were of children under five and thus not eligible for vaccines. For the week starting 19 December, none of the five- to 11-year-old patients were fully vaccinated.
“The risks of Covid-19 for children are real,” said acting state health commissioner Dr Mary Bassett. “We are alerting New Yorkers to this recent striking increase in pediatric Covid-19 admissions so that pediatricians, parents and guardians can take urgent action to protect our youngest New Yorkers.”
The health department advised parents to protect “children who are five years and older by getting them fully vaccinated and protect children under five by making sure all of those around them have protection through vaccination, boosters, mask-wearing, avoiding crowds and testing”.
The California public health director, Dr Tomás Aragón, warned to expect rising admissions there.
“Why? Omicron is so contagious that it finds unvaccinated/non-immune people who are most vulnerable for hospitalisations and deaths.”
Throughout the pandemic, experts have said children are less likely to develop serious illness. For the week from 9 to 16 December, the American Academy of Pediatrics reported 169,964 pediatric Covid-19 cases, representing 1.8% to 4.1% of hospitalised patients.
